The complete peptide library
62 compoundsBPC-157
Body Protection Compound 157
One of the most versatile healing peptides. Accelerates recovery of gut lining, tendons, ligaments, and muscle tissue. Widely studied for injury repair and gut health.
TB-500
Thymosin Beta-4 fragment
A naturally occurring peptide that promotes cell migration, angiogenesis, and tissue repair. Studied for systemic healing and reducing inflammation throughout the body.
LL-37
Cathelicidin antimicrobial peptide
A human cathelicidin peptide with broad-spectrum antimicrobial, wound healing, and immune-modulating properties. Promotes angiogenesis and disrupts bacterial biofilms.
SS-31
Elamipretide / Szeto-Schiller peptide
A mitochondria-targeted antioxidant peptide that concentrates in the inner mitochondrial membrane, reduces oxidative stress, and protects cardiac and renal tissue.
Semax
ACTH 4-10 analog
A synthetic ACTH analog that upregulates BDNF, NGF, and VEGF. Enhances dopaminergic neurotransmission for improved focus, memory, and neuroprotection.
Selank
Tuftsin analog
An anxiolytic peptide that modulates GABA-A receptors and serotonin systems. Reduces anxiety without sedation or dependence — a cleaner alternative to benzodiazepines.
Dihexa
N-hexanoic-Tyr-Ile-(6) aminohexanoic amide
An extremely potent hepatocyte growth factor agonist that activates c-Met receptors to promote synaptogenesis and neuroplasticity. Among the most powerful nootropics studied.
CJC-1295
Growth Hormone Releasing Hormone analog
A GHRH analog that stimulates growth hormone release. Often stacked with Ipamorelin for synergistic GH pulse amplification, improved body composition, and recovery.
Ipamorelin
Ipamorelin acetate
A selective GH secretagogue with minimal side effects. Produces clean GH pulses without cortisol or prolactin elevation. Ideal for sleep quality, recovery, and lean mass.
Sermorelin
GRF 1-29 NH2
A synthetic GHRH analog that stimulates pulsatile GH secretion from the pituitary. The fully compoundable alternative to CJC-1295 — on the 503A bulks list.
Tesamorelin
Egrifta (FDA-approved brand)
An FDA-approved GHRH analog that specifically targets visceral abdominal fat. Reduces VAT, improves lipid profiles, and has cognition data in older adults.
Semaglutide
Ozempic / Wegovy analog
A GLP-1 receptor agonist that regulates appetite, blood sugar, and promotes significant fat loss. The most clinically validated peptide for metabolic health optimization.
Tirzepatide
Mounjaro / Zepbound analog
A dual GLP-1 and GIP receptor agonist (twincretin) that outperforms semaglutide in head-to-head weight loss trials, reaching ~20–22% body weight reduction.
AOD-9604
Anti-Obesity Drug 9604
A fragment of HGH (amino acids 176–191) that activates beta-3 adrenergic receptors to stimulate targeted fat mobilization without the IGF-1 side effects of full HGH.
GHK-Cu
Copper Peptide GHK-Cu
A naturally occurring copper-binding peptide with powerful regenerative properties. Stimulates collagen synthesis, wound healing, and has potent antioxidant effects.
Epitalon
Epithalamin / Epithalon
A pineal-derived tetrapeptide that activates telomerase to elongate telomeres. Regulates melatonin production and circadian rhythms for comprehensive anti-aging.
SNAP-8
Acetyl Octapeptide-3
A topical octapeptide that competes with SNAP-25 in the SNARE complex, relaxing facial muscles to reduce expression lines. A non-injection alternative to Botox.
KPV
Lys-Pro-Val (MSH fragment)
A C-terminal tripeptide of alpha-MSH that binds melanocortin receptors to exert potent anti-inflammatory effects. A standard for gut inflammation and IBD research.
Thymosin Alpha-1
Thymalin / Zadaxin
A naturally occurring thymic peptide that activates T-lymphocytes, NK cells, and dendritic cells. Approved in 35+ countries for hepatitis and cancer immunotherapy support.
Glutathione
GSH / Reduced Glutathione
The body's master endogenous antioxidant. Neutralizes reactive oxygen species, supports liver detoxification, and maintains immune cell function. Popular as IV infusion therapy.
