AOD-9604 Reconstitution Calculator
A modified fragment of human growth hormone studied in lipolysis research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted AOD-9604 preparation, plus the mass-to-molar conversions for its stated molecular weight.

The pre-filled example, step by step
The inputs above are the neutral reference preparation this site uses everywhere the calculator appears: a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of AOD-9604 and not an amount anyone should draw — they exist so the arithmetic is visible before you change anything.
- Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for AOD-9604 is approximately 1.377 mM at its stated molecular weight.
- Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
- Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
- Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for AOD-9604
Derived from the molecular weight recorded on the AOD-9604 entry: ~1815 g/mol — the entry states this as an approximate figure, so the equivalents below are approximate too. Concentration in molar units is what an in-vitro protocol is usually specified in.
| Quantity | Molar equivalent |
|---|---|
| 1 mg of AOD-9604 | 551 nmol (0.551 µmol) |
| 1 mcg of AOD-9604 | 0.551 nmol |
| A 1 mg/mL solution | 0.551 mM (551 µM) |
Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Handling questions for AOD-9604
How does AOD-9604 differ from unmodified HGH Fragment 176-191?
AOD-9604 is a stabilized analog of HGH Fragment 176-191: it adds a tyrosine residue at the N-terminus of the native fragment. This modification was engineered in preclinical work to improve metabolic stability and lipolytic activity relative to the raw fragment. Both are studied for fat metabolism, but AOD-9604 is the more characterized, stabilized version.
How should AOD-9604 be stored and reconstituted for research?
AOD-9604 is supplied as a lyophilized powder and is typically reconstituted with bacteriostatic or sterile water for laboratory handling. Lyophilized peptide is generally stored refrigerated (2-8 C) or frozen for longer terms; reconstituted solution is kept refrigerated and used within a limited window. A COA with HPLC purity (commonly >=98%) and mass-spec identity confirmation is standard.
