1. How much BAC water?

More water = easier to draw small doses precisely. Less water = fewer injections of larger volume. Common: 2–3 mL for a 5 mg vial.

2. Which syringe?

U-100 (100 units/mL) is the standard for most peptide dosing. U-50 and U-40 exist for larger doses per unit or veterinary use.

3. mcg vs mg

1 mg = 1000 mcg. A 300 mcg BPC-157 dose is 0.3 mg.

4. Storage

Reconstituted peptides generally last ~28 days refrigerated. Check per-peptide guidance in the library.
