What to expect
Typical timeline
General pattern for the Muscle category. Individual response varies.
- Week 1Deeper sleep, vivid dreams, possible morning hand tingling — normal GH-axis signals.
- Weeks 2–4Recovery between sessions improves. Modest fullness in muscles from mild water retention.
- Weeks 4–8Body comp changes become visible. Fat drops slightly, muscle looks fuller. Bloodwork check recommended.
- Weeks 8+Cycle off for at least equal time to restore natural pulsatility. Track IGF-1 if running longer.
The reconstitution math
- 1Reconstitute the 25 mg vial with 1 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 25,000 mcg/mL (25 mg/mL).
- 3For a 25 mg dose, draw 1.000 mL — that's 0 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 1 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
