Ipamorelin reconstitution and storage
Ipamorelin's numbers in one place: the selective pentapeptide, its mass, vial size, concentration table and what its report should show.
Published September 4, 2026
Ipamorelin is a five-residue ghrelin receptor agonist, and it was designed with one goal: hit that receptor and as little else as possible.

Identity
| Residues | 5 |
| Formula | C38H49N9O5 |
| Molecular weight | 711.85 g/mol |
| CAS | 170851-70-4 |
| Vial size we sell | 5 mg |
At 712 g/mol it is a full hundred lighter than GHRP-2 and 161 lighter than GHRP-6, which makes it unmistakable on a mass-spec line. GHRP-2 vs GHRP-6 vs ipamorelin sets the family out.

Ipamorelin vial sizes we sell, at four diluent volumes. Molarity uses 711.85 g/mol. Other volumes
A 5 mg vial is about 7.03 micromoles, roughly seven times what the same mass of a 5,000 g/mol peptide would give. If you are switching between a secretagogue and a large peptide at the same mg/mL, the molar concentrations are nowhere near each other. The ipamorelin calculator has the weight preset.
Handling
Bacteriostatic water down the glass, swirl, no shaking. Freezer for the dry powder, fridge once reconstituted, no repeated freeze-thaw. Reconstitution and storage guides.
Checking the report
Observed mass near 711.85, HPLC purity at 99% or higher, matching batch number, named lab. Look up a batch. Before you order, the Lab Reports tab on the product page sends you the latest batch's report by email.
The pairing
A ghrelin agonist and a GHRH analog act at different receptors, so protocols study them together. We sell that pairing as CJC-1295 no-DAC + ipamorelin in one vial, and CJC-1295 and ipamorelin explains why the two are paired. CJC-1295 DAC vs no-DAC explains why the no-DAC form is the one that gets paired, and sermorelin vs tesamorelin vs CJC-1295 covers the GHRH side of the family.
Every ipamorelin vial from pepuro ships free, from our Calgary, Toronto and Vancouver distribution centers, the same business day your e-Transfer clears, with a QR code on the vial that opens its independent, third-party lab report.

Frequently asked questions
What is the molecular weight of ipamorelin?
+
711.85 g/mol, formula C38H49N9O5. It is the lightest of the growth hormone secretagogues we carry.
Why is ipamorelin called selective?
+
It was designed to act at the ghrelin receptor with far less activity at the other endocrine pathways the older hexapeptides touch. Fewer confounding variables in a research model.
How much water do I add to a 5 mg ipamorelin vial?
+
1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. At 711.85 g/mol, 5 mg is about 7 micromoles.
Why is ipamorelin the one used in blends?
+
Because it is selective. When a protocol pairs a ghrelin agonist with a GHRH analog, ipamorelin keeps the ghrelin side clean so the GHRH side is what varies.
