Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
Follistatin-344 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
Convert mcg to mg by dividing by 1000. For example, 100 mcg = 0.1 mg; 300 mcg = 0.3 mg; 500 mcg = 0.5 mg. Enter the mg value in the “Desired dose” field. The calculator works with decimals. Double‑check that you entered mg, not mcg – entering 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 → 0.2 mg = 0.02 mL = 2 units on a 100‑unit syringe. Any volume below 4 units is marked “Poor” because it is too small to measure accurately. To fix this, use a larger BAC volume or a smaller vial:
10 mg + 5 mL BAC → 2 mg/mL → 0.2 mg = 0.1 mL = 10 units → “Best”
5 mg + 5 mL BAC → 1 mg/mL → 0.2 mg = 0.2 mL = 20 units → “Best”
The calculator’s color coding helps you find a more accurate dilution.
10 mg + 5 mL BAC → 2 mg/mL → 0.2 mg = 0.1 mL = 10 units → “Best”
5 mg + 5 mL BAC → 1 mg/mL → 0.2 mg = 0.2 mL = 20 units → “Best”
The calculator’s color coding helps you find a more 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)
Avoid 1 mL BAC with small doses – it gives very high concentration and tiny volumes. The calculator highlights green (Best) for the most accurate draws.
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)
Avoid 1 mL BAC with small doses – it gives very high concentration and tiny volumes. The calculator highlights green (Best) for the most accurate draws.
No, the calculator assumes complete solubility in plain bacteriostatic water at the concentrations generated by 1,2,3,5 mL BAC. Follistatin‑344 may not dissolve well in straight BAC water, especially at higher concentrations (e.g., 10 mg in 1 mL = 10 mg/mL). Many protocols recommend adding a small amount of dilute acetic acid or using sterile water with pH adjustment. The calculator does not warn about this – you must research the correct reconstitution method for your specific formulation. If the solution turns cloudy or leaves particles, do not inject it.
Yes, if you successfully reconstituted it with an appropriate solvent (e.g., bacteriostatic water with or without acetic acid) and store it refrigerated (2–8°C). Bacteriostatic water preserves the solution for about 28 days. For a 10‑day cycle at 0.3 mg/day, total needed = 3 mg. A 5 mg vial is sufficient. The calculator’s “Doses per vial” display helps you plan: 5 mg / 0.3 mg ≈ 16 doses. However, Follistatin‑344 may degrade faster in solution than some peptides. If you notice any loss of effectiveness or precipitation after a few days, consider making smaller batches or using sterile vials to split the reconstituted solution.
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.
