How Growth-Hormone Secretagogues Actually Work

CJC-1295, Ipamorelin, and the biology behind why they're almost always stacked together, not run alone.

BPC-157 vs. TB-500: Two Repair Mechanisms, Not One

They get stacked so often they're treated as interchangeable — but they work on completely different systems, and that's exactly why they're paired.

Why Retatrutide Isn't Just "Stronger Semaglutide"

Semaglutide hits one receptor. Retatrutide hits three. That's a difference in kind, not just in dose — and it explains the slower titration curve.

Why NAD+ Causes Flushing (and Why Injection Speed Fixes It)

The single most common complaint about NAD+ isn't about the compound — it's about how fast it's pushed in.

Why Semax and Selank Are Sprayed, Not Injected

Both are ACTH/tuftsin-derived peptides built to cross into the brain — and the nasal route is doing real mechanistic work, not just added convenience.

MOTS-c and the Strange Story of Mitochondrial-Derived Peptides

It isn't encoded in your nuclear DNA at all — MOTS-c comes from a gene hiding inside mitochondrial DNA, a genome most people don't know produces proteins.

Kisspeptin and the HPG Axis: Why the Dosing Schedule Looks So Different

Every other protocol on this site doses once or twice a day at most. Kisspeptin-10 is dosed several times a day — and that's a direct consequence of where it sits in the hormone cascade.

Why Some Protocols Cycle and Others Don't

BPC-157 runs in bursts around an injury. CJC-1295 runs for months. NAD+ often doesn't stop at all. The pattern isn't random.
