Body Protection Compound 157 · PL 14736

BPC-157 is a 15-amino-acid peptide fragment derived from human gastric juice. It is one of the most extensively researched peptides for tissue repair, demonstrating accelerated healing of tendons, ligaments, muscle, bone, and gut lining in animal models. It appears to upregulate growth hormone receptors and promote angiogenesis at injury sites.

CJC-1295 with DAC · DAC:GRF

CJC-1295 is a modified GHRH analog with a Drug Affinity Complex (DAC) that binds to serum albumin, dramatically extending its half-life compared to native GHRH. It produces sustained elevation of GH and IGF-1 levels over days rather than hours. Research focuses on body composition improvements, muscle growth, and fat loss through prolonged GH axis stimulation.

Delta Sleep Inducing Peptide · Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu

DSIP (Delta Sleep Inducing Peptide) is a nonapeptide first isolated from rabbit cerebral venous blood during electrically induced sleep. Research shows it promotes slow-wave sleep, reduces pain sensitivity, normalizes circadian rhythms, lowers cortisol, and exhibits stress-protective effects. It also stimulates LH release and may influence GH pulsatility. Multiple mechanisms of action are proposed; its receptor has not been fully characterized.

Epitalon · Epithalamin

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on the endogenous pineal peptide epithalamin. It is one of the most extensively studied longevity peptides, with Russian research demonstrating telomerase activation, telomere elongation, melatonin normalization, and extended lifespan in animal models. Long-term human studies show reduced all-cause mortality rates and improved biomarkers of aging.

HGH Frag 176-191 · Growth Hormone Fragment 176-191

Fragment 176-191 is the C-terminal amino acid sequence 176–191 of human growth hormone, closely related to AOD-9604. It mimics the lipolytic activity of natural GH without binding to the GH receptor, thus avoiding insulin resistance and proliferative effects. Research shows it reduces fat mass in animal models by enhancing fat metabolism and inhibiting new fat formation.

Copper Peptide GHK · Glycyl-L-histidyl-L-lysine copper

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Research demonstrates it stimulates collagen, elastin, and glycosaminoglycan synthesis, promotes wound healing, reduces inflammation, and activates protective antioxidant genes. Plasma levels decline with age, making it a significant anti-aging research target.

NNC 26-0161

Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. Unlike other GHRPs, it stimulates GH release with high selectivity — producing minimal cortisol, ACTH, or prolactin elevation. It is among the most studied GHRPs for its clean GH pulse profile, making it a preferred research peptide for GH axis studies with reduced side effect concern.

C₃₈H₄₉N₉O₅ · 711.86 Da

Thymosin Beta-4 Fragment · Tβ4 fragment

TB-500 is a synthetic version of the active region of Thymosin Beta-4, a naturally occurring peptide found in virtually all human cells. Research shows it promotes actin polymerization and cell migration, which accelerates wound healing, muscle repair, and vascular growth. It is particularly studied for its ability to reduce inflammation and promote cardiac tissue repair.
