Growth Hormone
Stimulate your body's own GH release
Growth hormone secretagogues work by signaling the pituitary gland to produce and release its own growth hormone — preserving the natural pulsatile rhythm that exogenous GH disrupts. This class includes GHRH analogs (Sermorelin, CJC-1295, Tesamorelin) and GHRPs (Ipamorelin, GHRP-6) that act on distinct receptor pathways for synergistic effect.
Tesamorelin is the only FDA-approved GHRH analog, with robust Phase 3 clinical data in human subjects.
Metabolic
Regulate appetite, insulin, and fat oxidation
Metabolic peptides act on the gut-brain axis to regulate hunger signals, slow gastric emptying, improve insulin sensitivity, and promote fat oxidation. GLP-1 receptor agonists like Semaglutide represent the most clinically validated peptide class in modern medicine, with Phase 3 data showing 15–24% body weight reduction.
Tirzepatide (dual GIP/GLP-1) achieved 22.5% body weight reduction in SURMOUNT-1 — the highest of any approved weight-loss drug at time of publication.
Longevity
Target the biology of cellular aging
Longevity peptides operate at the intersection of mitochondrial biology, telomere maintenance, and epigenetic regulation. MOTS-c is encoded in the mitochondrial genome itself — a remarkable evolutionary signal. Epithalon activates telomerase. NAD+ fuels the sirtuin pathway that governs DNA repair and metabolic resilience.
MOTS-c is one of the few peptides encoded in mitochondrial DNA, suggesting deep evolutionary conservation of its metabolic role.
Recovery
Accelerate tissue repair and reduce inflammation
Recovery peptides work through angiogenesis promotion, actin polymerization, and local growth factor upregulation to accelerate healing of tendons, ligaments, muscles, and gut tissue. BPC-157 has one of the broadest healing profiles of any studied peptide. TB-500 (Thymosin Beta-4) is the synthetic version of a naturally occurring repair peptide found in virtually all human tissues.
BPC-157 has shown consistent healing effects across 20+ animal model studies covering virtually every tissue type.
Nootropic
Enhance cognition, memory, and neuroprotection
Nootropic peptides cross or influence the blood-brain barrier to upregulate BDNF, NGF, and HGF/c-Met signaling — the growth factors that govern neuroplasticity, synaptogenesis, and cognitive resilience. Selank reduces anxiety without sedation. Semax improves working memory. Dihexa is studied for its potent synaptogenic effects.
Selank was developed by the Russian Institute of Molecular Genetics and has been studied in clinical trials for generalized anxiety disorder.
Skin & Repair
Collagen synthesis, wound healing, and skin renewal
Skin and repair peptides activate the genes responsible for collagen and elastin production, reduce the matrix metalloproteinases that degrade skin structure, and promote wound healing at the cellular level. GHK-Cu alone activates over 4,000 human genes. The GLOW Blend combines multiple peptides for synergistic aesthetic and repair effects.
GHK-Cu has been shown in studies to increase skin thickness by up to 120% and reduce fine lines by activating collagen and elastin genes.
Hormonal
Support the hormonal signaling axis naturally
Hormonal peptides work upstream of the endocrine system — at the hypothalamic and pituitary level — to support natural hormone production rather than replacing it. PT-141 activates central arousal circuits. Kisspeptin-10 triggers the GnRH pulse that governs testosterone and estrogen. Oxytocin modulates bonding, trust, and social behavior.
PT-141 (Bremelanotide) received FDA approval for hypoactive sexual desire disorder in premenopausal women in 2019.
Antioxidant
Neutralize oxidative stress at the cellular level
Antioxidant peptides and compounds work by replenishing the body's master antioxidant systems — particularly glutathione, the tripeptide that neutralizes reactive oxygen species in every cell. Oxidative stress is implicated in aging, inflammation, neurodegeneration, and metabolic dysfunction. Glutathione depletion accelerates with age and chronic stress.
Glutathione is the most abundant intracellular antioxidant in the human body, present in virtually every cell at millimolar concentrations.
GLP-1
The most clinically validated peptide class in medicine
GLP-1 (glucagon-like peptide-1) receptor agonists are incretin hormones that regulate blood glucose, appetite, and gastric motility. The class has produced the most successful peptide therapeutics in pharmaceutical history — Semaglutide (Ozempic/Wegovy) and Tirzepatide (Mounjaro/Zepbound) have transformed metabolic medicine. Retatrutide adds glucagon receptor agonism for triple-mechanism action.
Tirzepatide (dual GIP/GLP-1) achieved 22.5% body weight reduction in SURMOUNT-1 — the highest of any approved weight-loss drug at time of publication.
Supplies
Essential supplies for every peptide protocol
Research-grade supplies required for safe and effective peptide reconstitution and administration. Bacteriostatic Water (BAC Water) is the universal solvent for lyophilized peptides, maintaining sterility for up to 28 days after opening. Every peptide protocol starts here.
Bacteriostatic Water is the USP-standard reconstitution solvent for virtually all lyophilized peptides. The 3mL vial is optimized for single-vial reconstitution.
