Glossary

The peptide space has a jargon problem. GHRP, GHRH, IGF-1, lyophilised, subcutaneous — these terms appear in every study and most vendor listings without explanation. The glossary defines them plainly, links them to the articles and peptide pages that use each term, and doesn't treat you like someone who needs a disclaimer to handle a fact. If a term is stopping you from evaluating the evidence, start here.

State of the evidence

The peptide space runs on jargon that slows down anyone who didn't spend six years in a biochemistry lab. GHRP, GHRH, IGF-1, angiogenesis, lyophilised — these terms appear in every study and most vendor listings. The glossary is the reference layer: plain-language definitions, linked to the articles and peptide pages that use each term. If a term appears in the research and you're not sure what it means, start here.

Telomeres, explained: the countdown inside your cells — and why longevity science keeps circling it

WADA

Telomeres cap your chromosomes, and get shorter every time a cell divides. Reset that countdown and you'd slow ageing itself — the longevity holy grail. Here's the real biology, what could move it, and why telomere-lengthening as anti-ageing is still unproven in humans.

What is a peptide? The plain-language guide for starting from zero

Peptides are the short chains of amino acids your body already uses to send signals — repair this, burn that, grow here. Some are drugs you trust, like insulin. Others are early and genuinely exciting. Here is the plain map of what they are, what they might do for you, and where the science stands.
