- 2mg
- 2mL bacteriostatic water
- 1,000mcg/mL
- 4–7 days at 100mcg 3×/day
- Higher per-mg cost
- Best for short pilot studies or dose-finding phases—minimizes waste but requires frequent reconstitution
- 5mg
- 5mL bacteriostatic water
- 12–18 days at 100mcg 3×/day
- Moderate per-mg cost
- Optimal balance for most 8–12 week research protocols—depletes within stability window without excessive handling
- 10mg
- 10mL bacteriostatic water
- 24–33 days at 100mcg 3×/day
- Lowest per-mg cost
- Cost-effective only if your protocol genuinely uses 300–400mcg daily—otherwise you pay for peptide that degrades before use
- The bottom line: vial size is a consumption-rate decision, not a potency decision. The peptide molecule is identical across all vial sizes—what changes is how much you'll waste if your depletion rate doesn't match the 28-day stability ceiling.
