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.
CJC-1295 DAC 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. For example, 250 mcg = 0.25 mg; 500 mcg = 0.5 mg; 1 mg = 1 mg. Enter the mg value in the “Desired dose” field. Be careful: a common weekly dose of 2 mg is entered as 2, not 2000. The calculator handles decimals, so 0.25 and 0.5 work fine.
With 10 mg in 1 mL, concentration = 10 mg/mL. For 0.25 mg, volume = 0.025 mL = 2.5 units on a 100‑unit syringe. The calculator marks any volume below 4 units as “Poor” because it is too small to measure accurately. To fix this, use more BAC water: 10 mg + 5 mL BAC → 2 mg/mL → 0.25 mg = 0.125 mL = 12.5 units (now “Usable” or “Good”). Even better, use a 5 mg vial + 5 mL BAC → 1 mg/mL → 0.25 mg = 0.25 mL = 25 units → “Best”. The color coding guides you.
For a 1 mg dose on a 100‑unit syringe:
5 mg vial + 2 mL BAC → 2.5 mg/mL → 1 mg = 0.4 mL = 40 units (×5 → Best)
10 mg vial + 5 mL BAC → 2 mg/mL → 1 mg = 0.5 mL = 50 units (×5 → Best)
6 mg vial + 3 mL BAC → 2 mg/mL → 1 mg = 0.5 mL = 50 units (×5 → Best)
For a 2 mg dose, same concentrations: 5 mg + 2 mL BAC → 2.5 mg/mL → 2 mg = 0.8 mL = 80 units (still within 100‑unit syringe, ×5 → Best). The calculator highlights green (Best) for accurate draws.
5 mg vial + 2 mL BAC → 2.5 mg/mL → 1 mg = 0.4 mL = 40 units (×5 → Best)
10 mg vial + 5 mL BAC → 2 mg/mL → 1 mg = 0.5 mL = 50 units (×5 → Best)
6 mg vial + 3 mL BAC → 2 mg/mL → 1 mg = 0.5 mL = 50 units (×5 → Best)
For a 2 mg dose, same concentrations: 5 mg + 2 mL BAC → 2.5 mg/mL → 2 mg = 0.8 mL = 80 units (still within 100‑unit syringe, ×5 → Best). The calculator highlights green (Best) for accurate draws.
Yes, if you reconstituted with bacteriostatic water and store the vial refrigerated (2–8°C). Bacteriostatic water preserves the solution for about 28 days. For a twice‑weekly schedule, a 5 mg vial at 1 mg per dose gives 5 doses → 2.5 weeks. A 10 mg vial gives 10 doses → 5 weeks, but discard after 30 days even if some solution remains. The calculator’s “Doses per vial” display helps you plan. Always check for cloudiness or discoloration before drawing.
No, the calculator assumes a single peptide per vial. If you custom‑mix two peptides in one vial, you must calculate each separately. For example, if the vial contains 5 mg CJC‑1295 DAC + 5 mg GHRP‑2 (total 10 mg), and you add 2 mL BAC water, the concentration of each is 2.5 mg/mL. For a desired dose of 1 mg CJC‑1295 DAC, you need 0.4 mL = 40 units – but that same volume also contains 1 mg of GHRP‑2. Use the calculator for one peptide by entering its individual mg as the vial strength, but remember the other peptide is also present. For precise stacking, reconstitute separately or use a spreadsheet.
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.
