Peptide guides, breakdowns, protocols.

From telomere-maintaining Epithalon to senolytic FOXO4-DRI and the mitochondrial-protection of SS-31, here's a complete breakdown of the five most-discussed anti-aging peptides — what they do, how they target the underlying mechanisms of aging, and where each one fits.

Peptides are short chains of amino acids that act as signaling molecules in the body — and they've quietly become one of the most discussed categories in modern medicine. Here's a complete primer on what peptides are, how they differ from proteins, how they work, and why they matter in 2026.

A practical patient-focused guide to weight-loss peptides in 2026 — what's FDA-approved, how GLP-1s actually work in the body, who should avoid them, what to expect for side effects, and what they really cost across insurance, manufacturer programs, and telehealth.

From a $14 cult favorite to a $310 luxury hero, here's our curated guide to the best peptide serums of 2026 — what's actually in them, what each one does, and how to choose between copper peptides, signal peptides, and neuropeptides.

RFK Jr.'s HHS is signaling a major pivot on peptides — including a July 2026 FDA review that could expand legal access through compounding pharmacies. Here's what the proposed changes actually do, who stands to benefit, and the safety questions a mainstream peptide market raises.

From the famous BPC-157 and TB-500 stack to clinical immune modulators like Thymosin Alpha-1, here's a complete breakdown of the five most-discussed healing peptides — what they do, how they work, and where each one fits in injury recovery, gut health, and immune modulation.

From the classic CJC-1295 + Ipamorelin stack to direct anabolics like IGF-1 LR3 and myostatin inhibitors like Follistatin 344, here's a complete breakdown of the five most-discussed muscle-growth peptides — how they work, how they're dosed, and where each one fits.

From Tirzepatide to Orforglipron, the GLP-1 family has redefined what's possible in weight management. Here's a complete breakdown of the five most-discussed weight-loss peptides — what they do, how they work, and where each one fits.
