on a U-100 syringe for a 100mcg dose
Add 2 mL BAC water to your 2 mg vial. Draw to 10.0 units on a U-100 syringe for a 100mcg dose. This vial will last 20 doses.

Ipamorelin is the most selective growth hormone releasing peptide available, producing a clean GH pulse without spiking cortisol, prolactin, or appetite. Community evidence across hundreds of threads is strong. No human efficacy trial has passed yet. Most users cycle 8 to 12 weeks.

With a 2 mg vial and 2 mL bacteriostatic water, you'll get 1,000 mcg/mL. Each 100 mcg dose is 10 units on an insulin syringe. A 5 mg vial reconstituted with 2 mL gives 2,500 mcg/mL, so 200 mcg is 8 units and 300 mcg is 12 units per injection. The fasting window is the thing most beginners mess up. You need at least two hours with no food before injection. Insulin triggers somatostatin release, which completely blocks the GH pulse. Eating within that window isn't "suboptimal"; it negates the injection entirely. No food for 30 minutes after, either. Bedtime dosing is priority number one. It amplifies the natural nocturnal GH pulse. If you're dosing twice daily, the morning shot should be fasted on waking. Space injections at least eight hours apart. Store lyophilized vials at 2 to 8 degrees Celsius. After reconstitution, keep refrigerated and use within three to four weeks. Toss anything cloudy or with particles floating in it. If you see zero sleep improvement after two weeks with correct fasting timing, suspect the product before blaming the protocol. Get an IGF-1 lab at week four to confirm the peptide is actually working. Vendor quality varies significantly.
