Peptide Dosage Calculator
Convert vial strength, reconstitution volume and target dose into clear syringe units. Supports mg-labeled vials and pre-mixed mL products. Peptide Guide Table · r/BioHackingGuide
Calculator Inputs
micrograms — most peptides (e.g. BPC-157, TB-500)
Total peptide mass labeled on your vial (e.g. 5 mg, 10 mg)
mL and cc are identical (1 mL = 1 cc). More water = easier to measure small doses.
Used to calculate daily usage and days per vial.
Standard U-100 insulin syringes (100 IU = 1 mL).
Recommended BAC water: 2 mL
This gives ~10 units per dose — easy to read on most syringes.
