HGH Fragment 176-191 Reconstitution Calculator
A 16-amino-acid C-terminal fragment of human growth hormone studied in lipolysis-related research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted HGH Fragment 176-191 preparation, plus the mass-to-molar conversions for its stated molecular weight.

Syringe capacity
Whole administrations exclude dead space, handling losses and expiry. A calculated quantity is not a guarantee of usable supply. No rounding to a nearby syringe mark is performed.
Protocol schedule
Schedule an existing prescribed or approved protocol. This tool cannot determine how often you can safely take a peptide. Frequency, dose, reconstitution, storage and discard instructions must come from the product label and your clinician or pharmacist.
04 / Your calendar
Complete your calculation and timing to build a schedule.
Calculations stay in this browser. Saving is optional and device-local. Calendar export creates a file; import it into your calendar and configure reminders there. PeptiDex does not send notifications.

A separate worked example, step by step
This separate arithmetic example uses a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of HGH Fragment 176-191 and not an amount anyone should draw — these figures only illustrate the arithmetic.
- Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for HGH Fragment 176-191 is approximately 1.376 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 HGH Fragment 176-191
Derived from the molecular weight recorded on the HGH Fragment 176-191 entry: ~1817 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 HGH Fragment 176-191 | 550.4 nmol (0.5504 µmol) |
| 1 mcg of HGH Fragment 176-191 | 0.5504 nmol |
| A 1 mg/mL solution | 0.5504 mM (550.4 µM) |
Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Handling questions for HGH Fragment 176-191
How does HGH Fragment 176-191 differ from AOD-9604?
AOD-9604 is a stabilized analog of HGH Fragment 176-191: it adds an N-terminal tyrosine to the native fragment to improve stability and lipolytic activity. HGH Fragment 176-191 is the unmodified sequence. Both are studied for lipolysis, but the raw fragment is less characterized and has a very short duration.
How is HGH Fragment 176-191 stored and reconstituted?
It is supplied as a lyophilized powder and reconstituted with bacteriostatic or sterile water for laboratory handling. Lyophilized peptide is stored refrigerated or frozen; reconstituted solution is kept refrigerated and used within a limited window. Research-grade material carries a COA with HPLC purity and mass identity.
