All dosing tables in the Ingredient Lab assume a standard reconstitution ratio. If you mix at a different ratio, recalculate draw volumes with the Dosing Calculator.
What reconstitution means
Research peptides ship lyophilized (freeze-dried powder). To produce a measurable solution you add a diluent — usually bacteriostatic (BAC) water, occasionally sterile water (NAD+ specifically).
The core relationship
concentration (mg/mL) = vial amount (mg) ÷ diluent volume (mL)
A 10mg vial + 1mL diluent = 10mg/mL. A 10mg vial + 2mL diluent = 5mg/mL. Same peptide, half the concentration, twice the draw volume for the same dose.
Reading an insulin syringe
A U-100 insulin syringe holds 1mL = 100 IU. So 1 IU = 0.01mL. Every "IU" figure in the dosing tables is just the volume marking on the barrel.
Diluent notes
- BAC water (benzyl alcohol preserved) — standard for most peptides; supports multi-week stability.
- Sterile water — used for NAD+, because benzyl alcohol degrades NAD+ faster. Mix NAD+ fresh and use within ~7 days.
