You are holding an Olympia Pharmacy tirzepatide vial and a U-100 insulin syringe. The label says something like "Tirzepatide 10 mg/mL" and your provider's note says "5 mg weekly." The syringe is in units, not milligrams. At 10 mg/mL, 5 mg of tirzepatide equals 50 units on a U-100 insulin syringe (0.5 mL). At 20 mg/mL, the same 5 mg dose equals 25 units (0.25 mL). At 5 mg/mL, the same 5 mg dose equals 100 units (1.0 mL). The concentration printed on your Olympia vial decides the math, not the brand. Olympia Pharmacy is a US-based 503A and 503B-registered compounding facility that ships compounded tirzepatide through telehealth partners and direct prescriptions, typically at 10 mg/mL or 20 mg/mL concentrations. Read the concentration off your vial first, then use the matching chart below.
| Quick Reference | Detail |
|---|---|
| Pharmacy type | 503A and 503B compounding facility |
| Common concentrations shipped | 5 mg/mL, 10 mg/mL, 20 mg/mL |
| Most common shipped concentration | 10 mg/mL |
| Typical vial size | 2 mL or 5 mL |
| Syringe used | U-100 insulin syringe (1 mL = 100 units) |
| FDA status of product | Compounded, not FDA-approved |
| Active ingredient | Tirzepatide (often + B12 or niacinamide) |
| Standard dose ladder | 2.5, 5, 7.5, 10, 12.5, 15 mg weekly |
Think of tirzepatide concentration like coffee strength. A shot of espresso and a large mug of drip coffee can both deliver the same caffeine; one is concentrated, one is dilute. Your tirzepatide dose in milligrams is fixed by the prescription. The volume you draw changes based on how concentrated the vial is. The literal version: at 10 mg/mL there are 10 mg of drug per 1 mL of liquid, so you need 0.5 mL to deliver 5 mg.
This is educational content. Verify the concentration printed on your vial before drawing any dose. Talk to your provider about any dose change.

What Olympia Pharmacy Actually Is
Olympia Pharmacy is a Florida-based compounding pharmacy that became one of the larger fulfillment players for compounded tirzepatide and semaglutide during the GLP-1 shortage years. It operates with both 503A pharmacy licensure (patient-specific compounding) and 503B outsourcing facility registration with the FDA (batch-level production with stricter oversight). That dual status is meaningful because 503B operations require GMP-level manufacturing controls and FDA inspection, which most 503A-only compounders do not have.
What Olympia does: - Compounds tirzepatide from active pharmaceutical ingredient under state and federal pharmacy regulation - Fills prescriptions routed through telehealth partners and direct physician prescriptions - Dispenses tirzepatide at common concentrations of 5 mg/mL, 10 mg/mL, and 20 mg/mL - Ships cold-chain to states where it holds non-resident pharmacy licensure - Offers formulations as pure tirzepatide or with additives (B12 or niacinamide)
What Olympia does not do: - Dispense brand-name Mounjaro or Zepbound - Operate as a telehealth clinic (you reach Olympia through a prescriber) - Accept insurance for compounded tirzepatide - Guarantee shipping to every US state (licensure varies)
Why the 503B status matters: A 503B outsourcing facility is held to current Good Manufacturing Practice standards and is FDA-inspected. A 503A pharmacy is overseen by the state Board of Pharmacy and follows USP 797 and USP 800 standards but is not FDA-inspected at the manufacturing level. For a peptide injectable that goes into your subcutaneous tissue weekly for months, the 503B oversight tier is the more rigorous one. Not every Olympia product is dispensed under 503B; ask which tier your specific vial was compounded under.

The Olympia Tirzepatide Dosage Chart by Concentration
Read your vial label first. The concentration is printed in mg/mL near the drug name. Pick the chart below that matches your concentration. Do not apply a chart from a different concentration; the math will be wrong by 2x or 4x.
Concentration: 5 mg/mL (low-concentration starter or microdose vials)
| Target Dose (mg) | Volume to Draw (mL) | Units on U-100 Syringe |
|---|---|---|
| 2.5 mg | 0.50 mL | 50 units |
| 5 mg | 1.00 mL | 100 units (full syringe) |
| 7.5 mg | 1.50 mL | requires 2 draws |
| 10 mg | 2.00 mL | requires 2 draws |
| 12.5 mg | 2.50 mL | requires 3 draws |
| 15 mg | 3.00 mL | requires 3 draws |
5 mg/mL is uncommon for maintenance because the volumes get large fast. It is sometimes used for microdose protocols where the 0.5 mL draw is easy to subdivide.
Concentration: 10 mg/mL (the most common Olympia concentration)
| Target Dose (mg) | Volume to Draw (mL) | Units on U-100 Syringe |
|---|---|---|
| 2.5 mg | 0.25 mL | 25 units |
| 5 mg | 0.50 mL | 50 units |
| 7.5 mg | 0.75 mL | 75 units |
| 10 mg | 1.00 mL | 100 units (full syringe) |
| 12.5 mg | 1.25 mL | requires 2 draws |
| 15 mg | 1.50 mL | requires 2 draws |
10 mg/mL is the workhorse concentration. It covers the entire standard dose ladder up to 10 mg in a single syringe draw and uses easy round-number unit values. If you have a choice, this is the concentration most providers default to.
Concentration: 20 mg/mL (high-concentration vials for maintenance and high-dose patients)
| Target Dose (mg) | Volume to Draw (mL) | Units on U-100 Syringe |
|---|---|---|
| 2.5 mg | 0.125 mL | 12.5 units |
| 5 mg | 0.25 mL | 25 units |
| 7.5 mg | 0.375 mL | 37.5 units |
| 10 mg | 0.50 mL | 50 units |
| 12.5 mg | 0.625 mL | 62.5 units |
| 15 mg | 0.75 mL | 75 units |
20 mg/mL keeps the injection volume small even at the highest dose, which is more comfortable subcutaneously and easier to absorb. The trade-off is that small starting doses (2.5 mg = 12.5 units) live in the bottom corner of the syringe, where measurement error is greatest.
How to read these charts safely:
- 1.Read the concentration from the label. Not from a previous shipment, not from the prescription note, from this specific vial.
- 2.Pick the matching chart. Ignore the other two.
- 3.Cross-check with the tirzepatide dosage calculator.
- 4.Use a U-100 insulin syringe. Each unit equals 0.01 mL. The "units" column is just mL multiplied by 100.
- 5.For draws below 25 units, hold the syringe at eye level and confirm the line. Small volumes are where most dosing errors cluster.
For the underlying math and additional dose mappings, see tirzepatide dosage chart in units, tirzepatide units 2.5 mg, how many units is 7.5 mg of tirzepatide, and how many units is 12.5 mg of tirzepatide.
Standard Tirzepatide Titration Schedule (Applies to Olympia Vials)
The clinical titration ladder for tirzepatide is the same regardless of brand or compounding pharmacy. It comes from the SURMOUNT-1 trial protocol that established efficacy at 5, 10, and 15 mg weekly maintenance doses (Jastreboff et al., 2022). Olympia ships any concentration that matches the dose your provider wrote, and you titrate the milligram dose, not the volume.
| Week | Weekly Dose | Volume at 10 mg/mL | Notes |
|---|---|---|---|
| 1-4 | 2.5 mg | 0.25 mL (25 units) | Starter. Side effects peak weeks 1-3. |
| 5-8 | 5 mg | 0.50 mL (50 units) | First effective dose for many. |
| 9-12 | 7.5 mg | 0.75 mL (75 units) | Bridge dose. Hold longer if nausea returns. |
| 13-16 | 10 mg | 1.00 mL (100 units) | Common maintenance dose. |
| 17-20 | 12.5 mg | 1.25 mL (requires 2 draws or 20 mg/mL vial) | Optional; only if 10 mg has plateaued. |
| 21+ | 15 mg | 1.50 mL (requires 2 draws or 20 mg/mL vial) | Maximum approved dose. |
Rules of titration that apply to your Olympia vial: - Hold each dose at least 4 weeks before stepping up. Faster titration triggers more nausea and vomiting. - If side effects at a new dose are intolerable, drop back one step and hold for 4 more weeks before retrying. - Many patients reach maintenance at 5 or 10 mg and never need 15 mg. - Once at maintenance, you stay there indefinitely. Tirzepatide is a chronic medication, not a course of treatment. - The injection schedule is once weekly, same day each week. A 1 to 2 day window is acceptable; do not double up if you miss a dose by more than 4 days, just resume.
For full titration logic and tolerance management, see how to inject tirzepatide, best time to take tirzepatide, best injection sites for tirzepatide, and tirzepatide maintenance dose after weight loss.
For pharmacokinetics that justify the weekly cadence (5-day half-life, steady state at week 4), see (Bastin and Andreelli, 2023).
Quantified Mistakes That Send People to the ER
Tirzepatide dosing errors at the compounding-pharmacy level usually trace to one of these mistakes. Each one has a measurable consequence. The reason this is the most important section of any compounded GLP-1 article is that the FDA Adverse Event Reporting System has logged hundreds of dosing errors specifically tied to compounded GLP-1s (Hoffman et al., 2025).
Mistake 1: Using a 10 mg/mL chart on a 20 mg/mL vial. You aim for 5 mg (drew 50 units expecting 0.5 mL of 10 mg/mL). Your vial is 20 mg/mL. You actually injected 10 mg. That is double the intended dose. Expect 2 to 3 days of severe nausea, possible vomiting, real risk of dehydration, and potentially a hospital visit if you cannot keep fluids down.
Fix: Read the concentration off the vial label every single injection day. Not the previous week, not memory, the label.
Mistake 2: Using a 20 mg/mL chart on a 10 mg/mL vial. You aim for 10 mg (drew 50 units expecting 0.5 mL of 20 mg/mL). Your vial is 10 mg/mL. You actually injected 5 mg. That is half the intended dose. You will not lose weight at the rate you expect, and your provider may unnecessarily escalate to 12.5 or 15 mg looking for a response that the math, not the medication, was suppressing.
Fix: Same. Read the label.
Mistake 3: Misreading "20 units" as "0.20 mL" on the syringe. 20 units on a U-100 insulin syringe equals 0.20 mL because 100 units = 1 mL. These are the same number expressed differently. Confusing them sends people to draw "0.20 units" (essentially nothing) or "20 mL" (impossible in a 1 mL syringe). Both errors mean the dose did not happen, which means a missed week of treatment.
Fix: Use the units scale on the syringe. Ignore mL on insulin syringes; you draw to the units mark.
Mistake 4: Drawing from an Olympia vial that has been frozen accidentally. Tirzepatide is a peptide. Freezing breaks peptide structure. A frozen-then-thawed vial may look fine and inject normally but deliver a fraction of the active dose, or trigger an injection-site reaction from denatured protein. Olympia ships cold-chain. If your shipment arrived frozen (ice crystals visible, vial liquid solid), do not use it; contact Olympia for replacement.
Fix: Visually inspect every vial. Refrigerate at 2 to 8 C. Do not place near the freezer compartment.
Mistake 5: Injecting from a vial past its beyond-use date. Olympia tirzepatide carries a beyond-use date (BUD) printed on the label, typically 28 to 60 days after compounding or first puncture. Past that, sterility cannot be guaranteed and peptide degradation accelerates. Using an expired vial risks injection site infection and underdose.
Fix: Note the BUD when the vial arrives. Mark a calendar reminder for the discard date. See does tirzepatide expire and how long does tirzepatide last in the fridge.
How to Read an Olympia Pharmacy Tirzepatide Vial
Most dosing errors disappear when you can read the label competently. Here is what every Olympia tirzepatide vial should show.
Line by line, what to find on the label:
- 1.Drug name: "Tirzepatide" (or "Tirzepatide / Niacinamide" or "Tirzepatide / B12" if compounded with additives).
- 2.Concentration: Printed as mg/mL. Common values are 5 mg/mL, 10 mg/mL, or 20 mg/mL. This is the single most important number on the vial.
- 3.Total volume: Printed as mL. Common values are 2 mL, 4 mL, or 5 mL. Multiply concentration by volume to get total drug per vial. A 10 mg/mL vial of 4 mL contains 40 mg total.
- 4.Lot number: A traceable batch identifier. If you ever experience an adverse event, you cite the lot number when reporting to FDA MedWatch and to Olympia.
- 5.Beyond-use date (BUD): The date past which the vial should not be used. For compounded sterile preparations dispensed in multi-dose vials, BUD is typically 28 to 60 days from compounding or first puncture, depending on USP 797 classification.
- 6.Compounding pharmacy name and address: Olympia Pharmacy or the specific Olympia branch with address.
- 7.Storage instruction: "Refrigerate at 2 to 8 C. Do not freeze. Protect from light." This is standard for tirzepatide.
- 8.Patient name (for 503A patient-specific compounding): Your name, sometimes also the prescriber name.
What a complete and proper label looks like:
> Tirzepatide / Niacinamide > 10 mg/mL 4 mL > Lot 2026-0405-A > BUD 06/15/2026 > Refrigerate 2 to 8 C > Patient: [Your Name] > Olympia Pharmacy, Orlando FL
What a problem label looks like:
- Hand-written details (lot number written in pen on a printed label)
- No concentration printed
- BUD missing or expired on arrival
- Patient name wrong or missing on a 503A vial
- Cloudy or floating particulates visible inside
If anything on the label is missing or wrong, call Olympia before you inject. Replacement is free; an injection error from a bad vial is not.

How Olympia Compares to Other Compounders
Olympia is one of several large compounding pharmacies that became major tirzepatide suppliers during the GLP-1 shortage. Here is how it compares to peers on the dimensions that matter to a patient.
Olympia vs Empower Pharmacy: - Both are 503A and 503B-registered facilities - Empower is Houston-based and slightly larger by volume - Both ship cold-chain through telehealth partners and direct prescriptions - Empower has a longer publicly-documented track record on inspection findings - See empower tirzepatide dosing
Olympia vs Strive Pharmacy: - Both 503A/503B compounders dispensing similar concentrations - Strive is more frequently routed through high-volume telehealth like Hims and Hers - See strive pharmacy semaglutide dosage chart
Olympia vs Southend Pharmacy: - Southend is more vertical with a smaller telehealth partner network - Olympia ships a wider geographic footprint - See southend pharmacy tirzepatide complete guide
Olympia vs Citizen Meds, Orderly Meds, Priority Meds, Tranont: - These are telehealth platforms that often route to Olympia or competing compounders - The compounding pharmacy is the fulfillment side; the telehealth platform is the patient-facing side - See citizen meds tirzepatide complete guide, orderly meds tirzepatide complete guide, priority meds tirzepatide complete guide, and tranont glp1 complete guide
Olympia vs brand Mounjaro or Zepbound: - Brand product is FDA-approved, fully standardized, stability-tested under FDA review - Compounded product (including Olympia) is not FDA-approved - Brand price is roughly $1,060 per month list, ~$350 to $550 via LillyDirect self-pay - Compounded price through telehealth is roughly $200 to $400 per month - See tirzepatide cost with insurance and where to buy tirzepatide
The decision tree most patients should use: 1. If insurance covers brand Zepbound at a reasonable copay, use brand. Lowest regulatory risk. 2. If insurance does not cover and you can afford LillyDirect ($350 to $550/month), use brand self-pay. 3. If neither of the above is sustainable, use a telehealth-routed compounded product through a vetted compounder like Olympia ($200 to $400/month). Verify the legitimacy checklist below.

The Compounding Pharmacy Legitimacy Checklist
Before trusting Olympia or any compounder, verify these.
1. State pharmacy licensure. Olympia must hold a license in Florida (its origin state) and a non-resident pharmacy license in your state. Verify on your state Board of Pharmacy site.
2. 503A or 503B registration. Olympia is registered under both. 503B status means FDA-inspected and held to GMP standards for batch-level production. Ask which tier your specific vial was compounded under.
3. PCAB accreditation (optional but a positive signal). PCAB accreditation is a voluntary quality program for 503A compounders. Not all 503B operations seek it because they have stricter FDA oversight already.
4. Complete vial label. Drug name, concentration, total volume, lot number, BUD, pharmacy name, storage instructions, patient name (for 503A).
5. Cold-chain shipping. Tirzepatide must arrive cold. Olympia ships in insulated cold packs. Check the cold pack temperature on arrival; refrigerate immediately.
6. Prescriber licensed in your state. The prescriber writing your tirzepatide order must be licensed in the state you live in, not just any US state.
7. Refund policy for unshipped or defective doses. Legitimate operations refund or replace bad shipments. Ask before paying.
8. Transparent regulatory posture. Tirzepatide compounding legality has shifted multiple times in 2024 and 2026 as FDA moves the drug on and off the shortage list. A legitimate provider explains the current legal basis for your prescription.

Frequently Asked Questions
What concentration does Olympia Pharmacy ship tirzepatide at?
Most commonly 10 mg/mL. Olympia also ships at 5 mg/mL for low-dose or microdose protocols and at 20 mg/mL for high-dose patients who want a smaller injection volume. The exact concentration is printed on your vial label. Always read it before drawing a dose. For underlying math, see tirzepatide dosage chart in units.
How many units is 5 mg of Olympia tirzepatide?
It depends on the concentration on your vial. At 10 mg/mL, 5 mg equals 50 units (0.5 mL) on a U-100 insulin syringe. At 20 mg/mL, 5 mg equals 25 units (0.25 mL). At 5 mg/mL, 5 mg equals 100 units (1.0 mL, the full syringe). Read the concentration off the label before drawing. See the tirzepatide dosage calculator to double-check.
How many units is 2.5 mg of Olympia tirzepatide?
At 10 mg/mL (the most common Olympia concentration), 2.5 mg equals 25 units (0.25 mL). At 20 mg/mL, 2.5 mg equals 12.5 units (0.125 mL), which is a very small volume in a U-100 syringe. At 5 mg/mL, 2.5 mg equals 50 units (0.5 mL). For more dose conversions, see tirzepatide units 2.5 mg.
How many units is 7.5 mg of Olympia tirzepatide?
At 10 mg/mL, 7.5 mg equals 75 units (0.75 mL). At 20 mg/mL, 7.5 mg equals 37.5 units (0.375 mL). At 5 mg/mL, 7.5 mg equals 150 units, which exceeds a standard 1 mL U-100 insulin syringe and requires two separate draws or a larger syringe. See how many units is 7.5 mg of tirzepatide for the full breakdown.
Is Olympia Pharmacy tirzepatide the same as Mounjaro or Zepbound?
No. Mounjaro and Zepbound are Eli Lilly's FDA-approved brand-name tirzepatide products. Olympia dispenses compounded tirzepatide, made by Olympia under 503A and 503B compounding rules using the raw tirzepatide active ingredient. The active molecule is the same. The finished product is regulated differently. Compounded tirzepatide is not FDA-approved. See is compound tirzepatide safe.
Is Olympia Pharmacy legitimate?
Olympia operates as both a 503A pharmacy and a 503B FDA-registered outsourcing facility. The 503B status places it under FDA inspection and GMP-level manufacturing standards, which is the higher tier of compounding oversight. As with any compounder, verify the specific vial label is complete, the prescriber is licensed in your state, and the legal basis for compounded tirzepatide is current. See the full legitimacy checklist below and vitastir tirzepatide.
What if my Olympia tirzepatide vial concentration does not match what my provider prescribed?
Stop. Do not inject. Call Olympia and your prescriber. Concentration mismatches between prescription and shipped product are a fixable error if caught before injection and a serious dosing error if not. Olympia will replace a mislabeled vial. Your prescriber will confirm the intended concentration in writing. See is compound tirzepatide safe for handling defective shipments.
How do I store Olympia tirzepatide after it arrives?
Refrigerate at 2 to 8 C immediately. Do not freeze. Keep the vial in the original packaging away from direct light. After first puncture, the vial is generally usable for 28 to 60 days depending on the BUD printed on your label. Discard at the BUD even if liquid remains. See how long does tirzepatide last in the fridge and does tirzepatide need to be refrigerated for full storage protocols.
The Bottom Line
Olympia Pharmacy ships compounded tirzepatide at multiple concentrations, with 10 mg/mL as the most common and 20 mg/mL increasingly common for higher-dose patients. The dosage chart you need depends on which concentration is in your specific vial, not on the brand on the label. The math is fixed: at 10 mg/mL, 5 mg equals 50 units; at 20 mg/mL, 5 mg equals 25 units; at 5 mg/mL, 5 mg equals 100 units. Read the concentration before every draw.
Olympia's combined 503A and 503B status places it among the more rigorously overseen compounders for compounded GLP-1s, with FDA inspection at the 503B tier. That does not make compounded tirzepatide equivalent to brand Mounjaro or Zepbound on the regulatory dimension; only FDA-approved brand product holds that status. It does mean Olympia operates above the average bar for compounding pharmacies. Verify the vial label, the prescriber license, and the current regulatory basis for your prescription before each shipment.
The single most important habit for compounded tirzepatide patients is reading the concentration off the vial every injection day. The five mistakes documented above (using the wrong chart, misreading units vs mL, injecting frozen product, ignoring BUD, accepting an incomplete label) cause nearly all serious dosing errors at the patient level. Each one is preventable in 30 seconds of label inspection.
