Peptides

A comprehensive guide to peptide research for biohackers — categories, protocols, supplier quality, and the Australian regulatory context explained.

Epitalon is a tetrapeptide studied for telomerase activation and life extension. A balanced look at the Khavinson research programme, what it shows, and its limitations.

HCG acts on LH receptors to stimulate testosterone production — distinct from exogenous androgens. A research overview of its hormone support and fertility applications.

GHK-Cu modulates over 4000 genes and influences wound healing, inflammation, and hair growth. A research-focused deep dive into the copper peptide's biology.

A deep dive into IGF-1 LR3 — how the long arginine-3 analogue differs from native IGF-1, its mechanism on muscle satellite cells, and what the research shows.

Tesamorelin is an FDA-approved GHRH analogue with significant clinical data on visceral adipose tissue reduction. Here is what the research actually shows.

A comprehensive hub covering the major longevity peptide categories — Epitalon, MOTS-c, SS-31, Selank — mechanisms, evidence, and how they differ from performance peptides.

How Ipamorelin and CJC-1295 work synergistically to stimulate growth hormone release — mechanisms, selectivity, DAC vs no-DAC, and what the research shows.

A precise breakdown of the February 2026 FDA peptide reclassification — which peptides returned to Category 1, what changed in Australia under TGA, and what this means for researchers sourcing peptides in 2026.

An in-depth look at Melanotan II, the melanocortin system it acts on, how it stimulates melanogenesis, and what the preclinical and clinical research shows.
