Dosing Structure
Dose
200–250 mcg
Frequency
1-2x daily; before bed fasted (+ optionally morning fasted)
Notes
Standalone: 100mcg per dose, 1-2x daily fasted. Blended (with Ipamorelin or GHRP): 200–300mcg per peptide per injection. 1x Daily: Take directly before bed, fasted. If fasting before bed isn't possible (~2-3 hours after meal), consider taking in the morning. 2x Daily: Take before bed and first thing in the morning, fasted. Inject: Lower abdomen, outer thigh, back of upper arm. Break: 1-2 months.
Example Protocols
Dose: 200–250 mcg
Frequency: 1-2x daily; before bed fasted (+ optionally morning fasted)
Duration: 6-12 weeks
