Mixing Ipamorelin: What to Know Before You Reconstitute
Ipamorelin is a growth hormone secretagogue sold as a lyophilized powder, most commonly in 2 mg, 5 mg, and 10 mg vials. Its reconstitution is straightforward, and the practical questions are the same ones that come up with any microgram-dosed peptide: how much water to add so the draws are readable, and how to handle the vial when it is running alongside CJC-1295, which is the pairing most people are running.
Bacteriostatic water vs. sterile water
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative and is the standard choice for any vial that will be drawn from more than once. Sterile water has no preservative and is generally treated as single use. Ipamorelin is typically dosed frequently, so the vial is punctured many times, and bacteriostatic water is what people use.
How much water to add
The water volume sets concentration, not the amount of peptide. Ipamorelin doses are usually in the microgram range, so the choice matters mainly for readability of the draw.
Vial Water Concentration Per unit 200 mcg draw 300 mcg draw 2 mg 1 mL 2.0 mg/mL 20 mcg 10 units 15 units 5 mg 2 mL 2.5 mg/mL 25 mcg 8 units 12 units 5 mg 2.5 mL 2.0 mg/mL 20 mcg 10 units 15 units 10 mg 3 mL 3.33 mg/mL 33.3 mcg 6 units 9 units A useful trick visible in this table: mixing to a round 20 mcg per unit, as 5 mg in 2.5 mL does, makes mental math simple, since every 100 mcg is exactly 5 units. Several of the common water volumes are chosen for this reason rather than for anything about the peptide itself.
Mixing technique
Water down the inside wall, not onto the powder. Swirl slowly or let it sit until dissolved. No shaking. The result should be clear. Ipamorelin generally dissolves quickly.
Storage before and after mixing
Unopened vials keep cool and dark. Reconstituted vials go in the refrigerator with the standard 28 day discard convention from punctured bacteriostatic water. When ipamorelin runs alongside CJC-1295, the two vials are usually mixed on the same day and therefore expire on the same day, which is worth noting somewhere other than memory.
The syringe
U-100 insulin syringes, 100 units per mL. As with other microgram-dosed peptides, the 0.3 mL and 0.5 mL syringes are often preferred because their markings are further apart and small draws are easier to read.
Common mistakes worth avoiding
Recurring ones: trying to combine ipamorelin and CJC-1295 in one vial, using too little water so doses land at 3 or 4 units, mcg to mg conversion errors, forgetting that two vials mixed the same day share an expiration, and reusing a previous unit count after mixing a new vial at a different volume.
