Frequently Asked
How do I reconstitute Ipamorelin?
Add 2 mL of bacteriostatic water to a 5 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 2500 µg/mL.
What is the recommended dose of Ipamorelin?
A typical research dose is 300 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a Ipamorelin vial?
A 5 mg vial reconstituted with 2 mL BAC water yields approximately 16 doses at 300 µg each.
How many IU is 300 µg of Ipamorelin on a syringe?
With a 5 mg vial reconstituted in 2 mL bacteriostatic water, the concentration is 2500 µg/mL. For a 300 µg dose: Volume = 300 µg ÷ 2500 µg/mL = 0.12 mL. Draw to the 12 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.
What does a Ipamorelin dosage calculator do?
A Ipamorelin dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (5 mg), reconstitution volume (2 mL), and target dose to get the precise line to draw on an insulin syringe.
What is the Ipamorelin reconstitution calculator formula?
Draw volume (mL) = Dose (µg) divided by Concentration (µg/mL). For a 5 mg vial with 2 mL BAC water: concentration = 2500 µg/mL. For a 300 µg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
Peptide Intelligence
What is the half-life of Ipamorelin?
Ipamorelin has a short half-life of approximately 2 hours after subcutaneous injection, making it suitable for pulsatile GH release mimicry. Most protocols use 2–3 injections daily, often upon waking, pre-workout, and pre-sleep.
Why is Ipamorelin considered selective compared to other GHRPs?
Ipamorelin selectively stimulates GH release with minimal effect on cortisol, prolactin, or ACTH, unlike GHRP-2 and GHRP-6 which significantly elevate cortisol and prolactin. This selectivity makes Ipamorelin better tolerated in long-term protocols.
Is Ipamorelin typically stacked with a GHRH peptide?
Ipamorelin is most commonly stacked with CJC-1295 (No DAC) in a 1:1 ratio. CJC-1295 activates GHRH receptors while Ipamorelin activates ghrelin receptors, producing synergistic GH release that exceeds either peptide alone.
