Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.

- Shaking the vial aggressively.
hGH Fragment 176-191 Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
Divide mcg by 1000 to get mg. For example, 250 mcg = 0.25 mg; 500 mcg = 0.5 mg. Enter the mg value in the “Desired dose” field. The calculator works with decimals. Do not enter the mcg number directly – 500 mg instead of 0.5 mg would be 1000× too high and likely impossible to draw.
With 10 mg in 1 mL, concentration = 10 mg/mL → 0.25 mg = 0.025 mL = 2.5 units on a 100‑unit syringe. Any volume below 4 units is marked “Poor” because it is very hard to measure accurately. To fix this, use more BAC water or a smaller vial:
10 mg + 5 mL BAC → 2 mg/mL → 0.25 mg = 0.125 mL = 12.5 units (“Usable”)
5 mg + 5 mL BAC → 1 mg/mL → 0.25 mg = 0.25 mL = 25 units (→ Best)
6 mg + 3 mL BAC → 2 mg/mL → 0.25 mg = 0.125 mL = 12.5 units (“Usable”)
The color coding helps you find the most accurate dilution.

The color coding helps you find the most accurate dilution.
For a 0.3 mg dose on a 100‑unit syringe, aim for units that are multiples of 5:
5 mg vial + 5 mL BAC → 1 mg/mL → 0.3 mg = 0.3 mL = 30 units (×5 → Best)
6 mg vial + 3 mL BAC → 2 mg/mL → 0.3 mg = 0.15 mL = 15 units (×5 → Best)
10 mg vial + 5 mL BAC → 2 mg/mL → 0.3 mg = 0.15 mL = 15 units (×5 → Best)
5 mg vial + 2 mL BAC → 2.5 mg/mL → 0.3 mg = 0.12 mL = 12 units (not ×5, but “Good”)
Avoid 1 mL BAC with small doses – it gives very high concentration and tiny volumes. The calculator highlights green (Best) for multiples of 5 units.
5 mg vial + 5 mL BAC → 1 mg/mL → 0.3 mg = 0.3 mL = 30 units (×5 → Best)

Yes, if you reconstitute with bacteriostatic water and store the vial refrigerated (2–8°C). Bacteriostatic water preserves the solution for about 28 days. For a typical dose of 0.25 mg twice daily (0.5 mg total per day), a 5 mg vial gives 10 days of doses (5 / 0.5 = 10). The calculator’s “Doses per vial” display helps you plan. Always inspect for cloudiness or particles before each use. If you use the vial over many days, be meticulous about sterile technique – wipe the rubber stopper with alcohol before each draw.
No, the calculator only performs dilution math – it does not distinguish between BAC water, sterile water, or saline. The concentration and unit calculations are identical regardless of the liquid. However, for multi‑day use (more than one injection), bacteriostatic water is strongly recommended because it contains 0.9% benzyl alcohol to prevent bacterial growth. Sterile water or saline lack preservatives and should only be used for single, immediate injections. The calculator does not warn about this – you must choose the correct reconstitution liquid for your intended use.
Practical takeaway: If your real goal is weight or metabolic health, the most useful next step is discussing approved treatment options with a clinician rather than relying on an unapproved compound.
