GROW

GH pulse plus direct IGF-1 for recomposition and recovery

Also known as: GROW Stack, CJC + Ipamorelin + IGF-1 LR3

RecompositionRecoveryPerformance

Why This Rating?

GROW stacks the pulsatile GH pairing (Mod GRF 1-29 + Ipamorelin) with IGF-1 LR3, a long-acting IGF-1 analog that acts directly and potently on muscle. IGF-1 LR3 is the driver here (rated 7 on its own); adding a GH pulse on top makes this a genuine anabolic protocol, well above the GH-peptide-only combos.

Overview

A GH-optimization stack that layers direct anabolism on top of the CJC/Ipamorelin GH pulse: Mod GRF 1-29 + Ipamorelin drive your own GH, and IGF-1 LR3 supplies a potent, long-acting IGF-1 signal directly to muscle tissue.

What's In It

Protocol

Run the GH pair (Mod GRF + Ipamorelin) subcutaneously 1-3x/day on an empty stomach; add IGF-1 LR3 ~20-50 mcg/day, often post-workout. IGF-1 LR3 is typically run in shorter blocks (~4-6 weeks) within a longer GH-peptide run. Monitor blood glucose: IGF-1 can cause hypoglycemia.

Typical cycle length:8-16 weeks

Cautions

  • IGF-1 LR3 can cause hypoglycemia. Keep fast carbs on hand and monitor blood glucose.
  • IGF-1 promotes growth of all tissue indiscriminately; a theoretical concern where any tumor/organ growth is possible.
  • Eat no fat/carbs ~30 min around the GH-peptide shots.
  • WADA-prohibited (S2. Peptide Hormones): not for tested athletes.

Post Cycle Therapy (PCT)

PCT Not Required

Not hormonal (does not affect the HPTA). No PCT required.
