Metabolic peptides

Mitochondrial, insulin-pathway, and HPG-axis peptides for metabolic flexibility and endocrine support.

MOTS-c is the mitochondrial-derived standout, tied to insulin sensitivity and often used as a stack adjunct during cuts. HCG (Human Chorionic Gonadotropin) sits here for its LH-mimetic role: testosterone preservation alongside TRT and HPG-axis restart in PCT contexts.

SS-31 (Elamipretide / MTP-131)

Boosts your cells' energy production at the source. A mitochondria-targeting peptide that concentrates in the inner mitochondrial membrane to support ATP production, FDA-approved in 2025 as FORZINITY for Barth syndrome, the first mitochondria-targeted drug, with all other uses off-label.

HCG (Human Chorionic Gonadotropin)

Used clinically to boost fertility and restart the body's own testosterone production after a suppressive cycle. It's a glycoprotein hormone that works by mimicking LH at the testicular Leydig cell.
