IGF-1 vs IGF-1 LR3: Why the Modified Version Lasts Twelve Times Longer

IGF-1 LR3 was engineered to escape the binding proteins that suppress native IGF-1 in serum. The modification is a 13-residue extension and an arginine substitution. Here is what those two changes do and why the cell-culture and in vivo data look different than they do for the native peptide.

AOD 9604 Research: What 900 Clinical Trial Participants Taught Us About This GH Fragment

AOD 9604 went through multiple human clinical trials enrolling 900+ participants before Metabolic Pharmaceuticals discontinued it in 2007. The story of what those trials found — and why the compound failed commercially despite real efficacy signals — is one of the most instructive in peptide research.

Growth Hormone Secretagogues Explained: The Researcher's Guide to GHRH and GHRP Peptides

GHRH analogs like CJC-1295 and ghrelin mimetics like Ipamorelin work through distinct pathways to stimulate the body's own GH production — a fundamentally different approach from exogenous growth hormone. Here's the endocrinology behind how they work.
