Body Protection Compound 157

A 15-amino-acid peptide derived from human gastric juice. The most-researched peptide for tissue repair, gut healing, and injury recovery. Works through nitric oxide signaling, angiogenesis, and collagen stimulation.

Glycyl-L-Histidyl-L-Lysine Copper Complex

A naturally occurring copper-binding tripeptide that declines with age. GHK-Cu resets gene expression toward a younger pattern, stimulates collagen synthesis, activates antioxidant defenses, and promotes tissue remodeling across skin, bone, and connective tissue.

Thymosin Beta-4 (Fragment)

A 43-amino-acid peptide identical to the active region of Thymosin Beta-4, the most abundant actin-binding protein in the body. TB-500 promotes cell migration, blood vessel formation, and tissue repair systemically — reaching injuries that localized treatments miss.

CJC-1295 (Modified GRF 1-29)

A 29-amino-acid growth hormone releasing hormone (GHRH) analog with enhanced stability. CJC-1295 extends the duration of natural GH pulses without disrupting pulsatile release patterns, providing sustained elevation of growth hormone and IGF-1 for recovery, body composition, and anti-aging.

Ipamorelin Acetate

A pentapeptide ghrelin receptor agonist that triggers clean, selective growth hormone pulses without raising cortisol or prolactin. Ipamorelin is considered the most selective GH secretagogue available, making it the preferred choice for those prioritizing minimal side effects alongside GH optimization.

Semaglutide (GLP-1 Receptor Agonist)

An FDA-approved GLP-1 receptor agonist originally developed for type 2 diabetes, now widely prescribed for weight management (Ozempic, Wegovy). Semaglutide reduces appetite centrally, slows gastric emptying, and improves insulin sensitivity. Notably, it is NOT metabolized by CYP enzymes — response variation is driven by receptor genetics, not liver metabolism.

Advanced Obesity Drug 9604 (hGH Fragment 177-191)

A modified 16-amino-acid fragment of human growth hormone (amino acids 177-191) with a tyrosine substitution. AOD-9604 retains the fat-metabolizing activity of full-length GH without stimulating IGF-1, meaning it promotes lipolysis and inhibits lipogenesis without the growth, insulin resistance, or proliferative risks of HGH.

KPV (Lys-Pro-Val)

A tripeptide derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). KPV retains the potent anti-inflammatory properties of the parent hormone without melanogenic (skin-darkening) effects. It targets gut inflammation through MC1R signaling and NF-kB suppression, making it a focused tool for IBD, colitis, and intestinal permeability.

Glucagon-Like Peptide-2

A 33-amino-acid peptide produced by intestinal L-cells. GLP-2 is the body's primary signal for intestinal growth and repair. Its analog teduglutide (Gattex) is FDA-approved for short bowel syndrome. GLP-2 stimulates crypt cell proliferation, increases villus height, enhances nutrient absorption, and restores gut barrier function.

Semax (ACTH 4-10 Analog with Pro-Gly-Pro)

A synthetic heptapeptide derived from ACTH (4-10) with a C-terminal Pro-Gly-Pro tripeptide extension for stability. Developed in Russia and approved there for stroke recovery and cognitive enhancement. Semax upregulates BDNF, modulates the melanocortin system, and supports neuroplasticity without stimulant-like side effects.

Selank (Tuftsin Analog with Pro-Gly-Pro)

A synthetic heptapeptide derived from the immunopeptide tuftsin, with a Pro-Gly-Pro extension for enzymatic stability. Developed alongside Semax at the Russian Academy of Sciences. Selank modulates GABA-ergic and serotonergic systems to reduce anxiety without sedation, while providing mild cognitive enhancement and immune modulation.

Epitalon (Ala-Glu-Asp-Gly)

A synthetic tetrapeptide based on the natural pineal gland peptide epithalamin. Epithalon activates telomerase, the enzyme that maintains telomere length, potentially slowing cellular aging. Discovered by Professor Vladimir Khavinson, it remains one of the most studied anti-aging peptides in gerontology.

Mitochondrial Open Reading Frame of the 12S rRNA Type-c

A 16-amino-acid peptide encoded by the mitochondrial genome — one of only a handful of known mitochondrial-derived peptides (MDPs). MOTS-c acts as a retrograde signal from mitochondria to the nucleus, activating AMPK and regulating metabolic homeostasis. It functions as an exercise mimetic, improving insulin sensitivity, fat oxidation, and cellular stress resilience.

SS-31 (Elamipretide / Bendavia / MTP-131)

A synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) that selectively targets cardiolipin in the inner mitochondrial membrane. SS-31 stabilizes electron transport chain function, reduces reactive oxygen species production at the source, and prevents mitochondrial permeability transition. Currently in clinical trials for heart failure, mitochondrial myopathy, and age-related mitochondrial dysfunction.

Thymosin Alpha-1 (Thymalfasin)

A 28-amino-acid peptide naturally produced by the thymus gland. Thymosin Alpha-1 is one of the most clinically validated peptides in existence — approved in over 35 countries for hepatitis B/C and as an immune adjuvant. It enhances T-cell maturation, dendritic cell function, and bridges innate and adaptive immunity.
