Ipamorelin reconstitution.

Ipamorelin vials are typically 2 mg or 5 mg. With 2 mL bacteriostatic water, common doses of 200-500 mcg map to 10-25 unit marks on a U-100 insulin syringe.

Ipamorelin specifics

What to know about this peptide.

Half-life

Half-life ~2 hours. Most protocols dose 2-3× daily, often before bed and pre-workout to align with natural GH pulses.

Stability after mixing

Refrigerate at 2-8°C after reconstitution. 28-day stability standard.

Typical use

Selective GH release without significant prolactin or cortisol elevation. Pairs synergistically with CJC-1295.

Not medical advice

The math on this page is correct for the listed vial and BAC-water volume. The decision to reconstitute and inject Ipamorelin belongs to you and a clinician who knows your full history — not to a webpage.

Frequently asked

Ipamorelin questions

What vial size is Ipamorelin usually sold in?

Ipamorelin most commonly ships as 2 mg or 5 mg of lyophilized powder. The standard reconstitution is 2 mL of bacteriostatic water, which yields clean unit-mark math on a U-100 insulin syringe for the doses used in most protocols.

How much bacteriostatic water do I add to a Ipamorelin vial?

The standard volume is 2 mL of bacteriostatic water. You can use more (easier to draw, lower concentration) or less (more concentrated, smaller draw volume) without changing the peptide itself — only the syringe math changes. The dose table on this page is pre-calculated for 2 mL.

What is the half-life of Ipamorelin?

Half-life ~2 hours. Most protocols dose 2-3× daily, often before bed and pre-workout to align with natural GH pulses.

How long does reconstituted Ipamorelin last in the fridge?

Refrigerate at 2-8°C after reconstitution. 28-day stability standard.

What is Ipamorelin typically used for?

Selective GH release without significant prolactin or cortisol elevation. Pairs synergistically with CJC-1295.

What syringe should I use for Ipamorelin?

U-100 insulin syringes (29–31 gauge, 8–13 mm needle) are standard for subcutaneous peptide injection. Each unit on a U-100 syringe equals 0.01 mL. The dose table above shows how many units to draw for each common dose, given the vial size and standard bacteriostatic water volume.
