The IGF-1 LR3 &
CJC-1295 / Ipamorelin
Performance Blueprint
The most mechanistically documented anabolic peptide stack — dual-receptor GH amplification via CJC-1295/Ipamorelin driving 4–8× pulse output, followed by IGF-1 LR3 converting that signal into genuine myofiber hyperplasia and accelerated lipolysis. Zero cortisol elevation. Maximum tissue remodeling.
The GH Cascade: How the Stack Works
CJC-1295 and Ipamorelin attack the pituitary through two independent receptor pathways simultaneously — producing a synergistic GH output no single agent can match.
Training Day Protocol
Peptide timing is not optional — post-workout IGF-1 LR3 injection capitalizes on the acute satellite cell activation window. Pre-sleep CJC/Ipa exploits slow-wave GH surge.
Why Each Compound
Each agent in this stack is mechanistically irreplaceable — they operate on distinct receptors and downstream pathways with zero redundancy.
CJC-1295 is a synthetic analog of GHRH that binds and activates pituitary somatotroph cells via the cAMP/PKA signaling cascade. Its DAC (Drug Affinity Complex) modification extends half-life to 7–10 days, producing sustained baseline GH elevation without disrupting natural pulsatility. Clinical studies demonstrate 4–8× amplification of mean GH pulse amplitude and dose-dependent increases in IGF-1 serum levels over 28-day protocols.
View productIpamorelin is a pentapeptide ghrelin mimetic acting exclusively at GHSR-1a to trigger calcium-mediated GH exocytosis from pituitary somatotrophs. Unlike older secretagogues (GHRP-2, GHRP-6), it produces no measurable elevation in cortisol, prolactin, or ACTH — making it the most selective GH pulse driver identified. Paired with CJC-1295 it exploits both GHRH-R and GHSR-1a simultaneously for synergistic, supra-physiological GH output.
View productIGF-1 LR3 is a long-acting recombinant IGF-1 analog with a 13-amino-acid N-terminal extension that blocks IGF Binding Protein sequestration — elevating bioavailability ~3× vs native IGF-1 and extending half-life to 20–30 hours. It activates PI3K/Akt/mTOR and Ras/MAPK pathways to drive muscle satellite cell proliferation and differentiation, producing genuine myofiber hyperplasia (new fiber creation) rather than hypertrophy alone. Post-workout injection routes the anabolic signal directly to recently stressed tissue.
