A Tanning Peptide That Accidentally Became Much More In the late 1980s, researchers at the University of Arizona had a straightforward goal: create a peptide that would stimulate skin pigmentation without requiring UV exposure. A sunless tan in a vial. What they got was Melanotan II — a compound that does trigger tanning, but also […]

Your body produces IGF-1 naturally. It’s one of the most important growth factors in biology — driving cell growth, protein synthesis, and tissue development. But there’s a catch: the moment IGF-1 enters the bloodstream, binding proteins grab onto it. Six different IGF-binding proteins (IGFBPs) sequester most circulating IGF-1, limiting how much actually reaches target tissues […]

In 1977, two Swiss researchers did something beautifully weird: they took blood from a sleeping rabbit, filtered out the small molecules, and injected them into an awake rabbit. The awake rabbit fell into deep delta-wave sleep. Something in the blood was carrying a sleep signal. They isolated it, sequenced it, and named it delta sleep-inducing […]

There’s an enzyme in your fat cells called NNMT. Its job, essentially, is to slow down your metabolism — it degrades a methyl donor that cells need to produce NAD+, the coenzyme that powers cellular energy production. More NNMT activity → less NAD+ → slower metabolism → more fat storage. It’s a brake pedal on […]

Three amino acids. That’s it. Lysine-Proline-Valine — a tripeptide so small it barely qualifies as a peptide at all. But KPV has generated outsized research interest because this tiny fragment, snipped from the tail end of alpha-MSH, packs anti-inflammatory activity that works through mechanisms most conventional anti-inflammatory compounds don’t touch. Here’s what the published research […]

Tesamorelin is a modified full-length GHRH analog with enhanced DPP-4 resistance. Review of preclinical and published research on visceral adipose tissue, hepatic fat, body composition, and cognitive effects.

Sermorelin and CJC-1295 are synthetic GHRH analogs that stimulate growth hormone release through the endogenous pathway. Review of mechanisms, half-life differences, synergy with GHS compounds, and preclinical applications.

MOTS-c is a mitochondrial-derived peptide that activates AMPK and regulates metabolic homeostasis. Review of its discovery, nuclear translocation mechanism, exercise-mimetic properties, and aging research.
