Melanotan II and PT-141 share a common origin but target different receptors and serve distinct research applications. This guide breaks down the science, side effects, and clinical data behind each peptide.
When tissue gets damaged — tendons, ligaments, muscle, bone — the body has repair systems that can be studied and potentially supported. BPC-157, TB-500, GHK-Cu, MGF, and IGF-1 LR3 are the peptides with the most research behind injury recovery. Here is how they compare.
Your body runs on peptides. Insulin, oxytocin, and GLP-1 are all natural peptides. Semaglutide, BPC-157, and Epithalon are synthetic. Here is what actually separates them — how they are made, how they are modified, and what those modifications do to their behavior in research.
Two of the most researched anti-aging peptides work in completely different ways. Epithalon targets telomeres and cellular aging. GHK-Cu repairs tissue and resets gene expression. Here is what the research actually shows.
A research-focused guide to the top peptides and compounds studied for endurance and athletic performance: AICAR, MOTS-c, SLU-PP-332, IGF-1 LR3, and TB-500 — mechanisms, published data, and comparison table.
A comprehensive pillar guide to GLP-1 receptor agonist peptides: how GLP-1 works, all major compounds including semaglutide, tirzepatide, retatrutide, cagrilintide, survodutide and mazdutide, clinical trial data, and the expanding research frontier.
A head-to-head research comparison of sermorelin (GHRH analog) and ipamorelin (selective ghrelin mimetic): mechanisms, GH release patterns, selectivity profiles, clinical history, and which peptide fits which research goal.
Five peptides have the strongest research track record in inflammation models. Each works through a different pathway — here is what the data shows and when each applies.
Most research peptides come as a white powder, not a liquid. That is not a coincidence — it is chemistry. Here is what lyophilization means and why it matters for peptide stability.
Ipamorelin and GHRP-6 both trigger growth hormone release — but they work differently and suit different research goals. Here is what the data shows.
