BPC-157

Body Protection Compound 157

Healing

Partial sequence of body protection compound derived from human gastric juice. Extensive research on tendon, muscle, and gut repair via multiple pathways.

Tirzepatide

GIP/GLP-1 Dual Agonist

GLP-1

Dual glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist. SURMOUNT trials demonstrated up to 22.5% body weight reduction.

Retatrutide

GIP/GLP-1/Glucagon Triple Agonist (GLP-3)

Triple agonist

Triple hormone receptor agonist targeting GIP, GLP-1, and glucagon receptors. Phase 2b showed ~24% body weight reduction at 48 weeks.

TB-500

Thymosin Beta-4 Fragment

Healing

Synthetic fragment of thymosin beta-4. Promotes actin upregulation, cell migration, and angiogenesis for tissue repair.

CJC-1295

Growth Hormone Releasing Hormone Analogue

GH

GHRH analogue available with or without Drug Affinity Complex (DAC). Without DAC: short pulsatile release. With DAC: extended half-life of ~8 days.

Ipamorelin

Selective Growth Hormone Secretagogue

GH

Selective GHRP with minimal cortisol and prolactin stimulation. Typically stacked with CJC-1295 for synergistic GH release.

Sermorelin

GHRH 1-29 Fragment

GH

Synthetic analogue of endogenous GHRH containing the first 29 amino acids. Stimulates pituitary GH release via natural signaling pathways.

GHK-Cu

Glycyl-L-Histidyl-L-Lysine Copper

Longevity

Naturally occurring copper peptide with demonstrated effects on wound healing, collagen synthesis, and stem cell activation.

PT-141

Bremelanotide

Melanocortin

Melanocortin receptor agonist acting centrally on MC3R and MC4R. FDA-approved (Vyleesi) for hypoactive sexual desire disorder.

Epithalon

Epitalon Tetrapeptide

Longevity

Synthetic tetrapeptide derived from epithalamin. Research focuses on telomere elongation and pineal gland regulation.
