The ultimate healing peptide
BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a protein found in the stomach. It has remarkable healing properties and is one of the most studied peptides for tissue repair.
TB-500
Systemic healing and recovery
TB-500 (Thymosin Beta-4) is a naturally occurring peptide that plays a crucial role in tissue repair and regeneration. Unlike BPC-157 which works locally, TB-500 acts systemically throughout the body.
Semaglutide
The gold standard for weight loss
Semaglutide is a GLP-1 receptor agonist originally developed for type 2 diabetes that has become the most effective peptide for weight loss. Marketed as Ozempic and Wegovy.
Tirzepatide
Next-gen dual-action weight loss
Tirzepatide is a dual GIP/GLP-1 receptor agonist that outperforms semaglutide in clinical trials. Marketed as Mounjaro and Zepbound, it achieves up to 22% body weight reduction.
Ipamorelin
Clean GH release without side effects
Ipamorelin is a selective growth hormone secretagogue that stimulates GH release from the pituitary gland. It's considered the cleanest GHRP with minimal side effects.
CJC-1295
Sustained GH release for muscle and recovery
CJC-1295 is a GHRH analogue that stimulates prolonged growth hormone release. Often stacked with Ipamorelin for synergistic effects on muscle growth and body composition.
HGH Fragment 176-191
Targeted fat burning without GH side effects
HGH Fragment 176-191 is a modified form of amino acids 176-191 of the GH polypeptide. It mimics the fat-burning effects of HGH without the growth-promoting properties.
PT-141
The libido peptide for men and women
PT-141 (Bremelanotide) is a melanocortin receptor agonist that works centrally in the brain to enhance sexual desire and function. Unlike Viagra, it works on the nervous system, not blood flow.
Semax
Russian cognitive enhancer
Semax is a synthetic peptide derived from ACTH that enhances cognitive function, mood, and neuroprotection. Widely used in Russia for neurological conditions.
Selank
Anti-anxiety and cognitive enhancement
Selank is a synthetic analogue of tuftsin with anxiolytic and nootropic properties. Developed in Russia, it reduces anxiety without sedation while enhancing cognitive performance.
Epitalon
The longevity peptide — telomere extension
Epitalon (Epithalon) is a tetrapeptide that activates telomerase, the enzyme responsible for lengthening telomeres. Developed by the St. Petersburg Institute of Bioregulation.
Retatrutide
Triple-action next-gen weight loss peptide
Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist in Phase 3 trials. Achieves up to 24% weight loss — the highest of any peptide therapy to date.
AOD-9604
Targeted fat loss fragment
AOD-9604 is a modified fragment of HGH (amino acids 176-191) with an additional tyrosine molecule. It specifically targets fat metabolism without affecting blood sugar or growth.
Cagrilintide
Amylin analogue for next-level weight loss
Cagrilintide is a long-acting amylin analogue being developed by Novo Nordisk. When combined with semaglutide (CagriSema), it achieves over 25% weight loss.
Sermorelin
The natural GHRH analogue for GH restoration
Sermorelin is a synthetic peptide consisting of the first 29 amino acids of growth hormone-releasing hormone (GHRH). It stimulates the pituitary gland to produce and release growth hormone in a pulsatile, physiological pattern.
GHRP-2
Potent GH secretagogue with strong clinical backing
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that acts on the ghrelin receptor to stimulate powerful growth hormone release from the pituitary. It is one of the most studied GHRPs and produces a stronger GH response than Ipamorelin, though with slightly more side effects.
GHRP-6
GH release with powerful appetite stimulation
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates growth hormone secretion through the ghrelin receptor. It is known for producing a strong GH response alongside significant appetite stimulation, making it popular in bulking protocols.
Hexarelin
The strongest GH-releasing peptide available
Hexarelin is a synthetic hexapeptide and the most potent growth hormone releasing peptide in its class. It produces the highest GH spike of any GHRP, but comes with a significant caveat: rapid receptor desensitization limits effective use to short cycles.
GHK-Cu
The copper peptide for skin regeneration and wound repair
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It plays a central role in wound healing, collagen synthesis, and tissue remodeling, making it one of the most studied peptides in dermatology and regenerative medicine.
KPV
Anti-inflammatory tripeptide for gut and immune health
KPV is a naturally occurring tripeptide (Lys-Pro-Val) derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). It retains the potent anti-inflammatory activity of alpha-MSH without its pigmentation or hormonal effects.
NAD+
The cellular energy molecule behind DNA repair and aging
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell that plays a central role in energy metabolism and DNA repair. Declining NAD+ levels are closely linked to aging, and supplementation has become one of the most researched anti-aging interventions.
Thymosin Alpha-1
Clinically proven immune modulator used worldwide
Thymosin Alpha-1 (Ta1) is a 28-amino-acid peptide naturally produced by the thymus gland. Marketed as Zadaxin, it is approved in over 30 countries for hepatitis B/C treatment and as an immune adjunct in cancer therapy.
DSIP
The sleep peptide for deep rest and stress adaptation
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide that promotes delta-wave sleep and modulates the stress response. Despite its short half-life, its effects on sleep architecture and recovery last for hours.
MK-677
Oral GH secretagogue for muscle, sleep, and recovery
MK-677 (Ibutamoren) is an orally active, non-peptide growth hormone secretagogue that mimics the action of ghrelin. It stimulates sustained GH and IGF-1 release without requiring injections, making it one of the most accessible growth hormone boosters available.
IGF-1 LR3
Long-acting IGF-1 for direct muscle growth
IGF-1 LR3 is a modified version of insulin-like growth factor 1 with a 13-amino-acid extension that gives it a dramatically longer half-life than native IGF-1. It acts directly on muscle tissue to stimulate hypertrophy, hyperplasia, and satellite cell activation.
Melanotan II
Melanocortin agonist for tanning, libido, and appetite control
Melanotan II is a synthetic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH) that activates melanocortin receptors throughout the body. It stimulates melanin production for skin darkening, increases sexual arousal, and suppresses appetite.
Kisspeptin
GnRH stimulator for natural testosterone and reproductive hormone support
Kisspeptin is a neuropeptide that sits at the top of the reproductive hormone cascade, directly stimulating GnRH neurons to trigger LH and FSH release. It plays a critical role in puberty onset, fertility, and testosterone regulation.
MOTS-c
Mitochondrial peptide that mimics exercise at the cellular level
MOTS-c is a 16-amino-acid peptide encoded by the mitochondrial genome. It acts as a metabolic regulator and exercise mimetic, improving insulin sensitivity, fat oxidation, and cellular energy production.
5-Amino-1MQ
NNMT inhibitor that reprograms fat cell metabolism
5-Amino-1MQ is a small molecule that inhibits nicotinamide N-methyltransferase (NNMT), an enzyme overexpressed in fat tissue. By blocking NNMT, it reactivates metabolic pathways in adipocytes and promotes fat loss without stimulant effects.
