CJC-1295 (no-DAC) + Ipamorelin GH Pulse for Lean Mass

Classic GHRH + GHRP pulse protocol used adjunctively during a resistance-training block.

Component peptides

The short-acting variant of CJC-1295 — a GHRH(1-29) analog with four amino-acid substitutions for degradation resistance but without the maleimidopropionic-acid moiety that produces albumin binding. Half-life on the order of 30 minutes, in contrast to the DAC version's multi-day exposure.

Ipamorelin

A pentapeptide growth-hormone secretagogue that binds the ghrelin/GHS-R1a receptor, reported as one of the most selective GH-releasers with minimal effect on cortisol or prolactin.

Goal

GHRH + GHRP pulse protocol during a resistance-training block.

Peptides

CJC-1295 (no-DAC), Ipamorelin

Why it works

Combined GHRH-analog and selective GHS-R1a agonism produce synergistic GH pulse amplitude while avoiding the cortisol and prolactin rise of earlier GHRPs.

How to use

CJC-1295 (no-DAC) — 100 mcg per pulse, 2-3x daily subcutaneous.
Ipamorelin — 100-300 mcg per pulse, co-administered with the GHRH arm.
