What Users Report
- Extremely strong hunger — frequently described as 'the hungriest you've ever felt in your life'
- The appetite stimulation is significantly more intense than GHRP-2 and makes eating massive meals easy
- Improved deep sleep quality, especially with bedtime dosing
- Increased recovery between sessions — training volume can be pushed higher
- Some water retention and bloating, particularly when eating large volumes of food
- More noticeable side effects than Ipamorelin (cortisol/prolactin elevation) but stronger GH release
- Ideal for hard-gainers or those in aggressive bulking phases who struggle to eat enough
Typical Timeline
Minutes 5–15: Intense hunger onset — be prepared with food available. Minutes 15–30: GH release peaks. Hours 1–2: Hunger gradually subsides after eating. Weeks 2–4: Sleep and recovery improvements. Weeks 4–12: Significant mass gain when paired with surplus calories and training.
