The most powerful GH-releasing peptide available -- it produces the biggest growth hormone spike of any peptide in this class. It also has heart-protective benefits. The downside is your body builds tolerance to it faster than other options.
What to Expect
Week 1–2
Strongest GH release of any GHRP. Improved sleep. Significant appetite increase. Cortisol and prolactin elevation likely.
Week 3–6
Rapid body composition changes. Strong recovery enhancement. Most potent of GHRPs for GH release but with most side effects.
Week 8+
Significant desensitization likely at this point. Benefits plateau. Not recommended for extended use.
Common Side Effects
Dosing
100-200 mcg subq 2-3 times daily. Keep cycles short -- 4-8 weeks max -- because your body stops responding as well over time.
