The compounds below appear together in published and ongoing research addressing metabolic health, lean-mass preservation, tissue repair, and connective-tissue biology as they relate to aging. Each is described individually here, based on its studied mechanism of action — not as a combined program.

Retatrutide

A triple hormone-receptor agonist (GLP-1/GIP/glucagon) studied in metabolic research for its relationship to appetite regulation, insulin sensitivity, and energy expenditure.

CJC-1295 + Ipamorelin

Growth-hormone secretagogues studied for their relationship to natural growth-hormone release, sleep quality, and lean-tissue-related research outcomes.

GHK-Cu

A copper-binding tripeptide studied for its relationship to collagen and elastin production, skin elasticity, and hair-follicle research models.

PT-141 (Bremelanotide)

A melanocortin-receptor agonist studied for its interaction with central-nervous-system pathways, distinct from hormone-based mechanisms of action.

BPC-157

Studied in tissue-repair research, including tendon, ligament, muscle, and gut-lining models.

TB-500 (Thymosin Beta-4 Fragment)

Studied in tissue-repair and cell-migration research, often alongside BPC-157 in the literature.

These profiles summarize each compound's studied mechanism of action as reported in the research literature; they do not constitute a combined regimen or usage recommendation.
