Question 1

What is a peptide reconstitution calculator?

Accepted Answer

A peptide reconstitution calculator helps you determine how much bacteriostatic water to add to a lyophilized (freeze-dried) peptide vial to achieve a desired concentration, and how many syringe units to draw per dose.

Question 2

How do I calculate my peptide dose in syringe units?

Accepted Answer

Divide your desired dose (in mcg) by the concentration of your reconstituted solution (mcg per unit). The Reconstitution Calculator computes this automatically from your vial amount, water volume, and dose.

Question 3

What is bacteriostatic water and how much do I use?

Accepted Answer

Bacteriostatic water (BW) is sterile water containing 0.9% benzyl alcohol used to reconstitute peptides. Typical amounts range from 1–3 mL per vial. The amount determines your concentration — more water means a lower concentration per unit.

Question 4

How do I calculate peptide cost per dose?

Accepted Answer

Divide the vial price by the total number of doses in the vial. Use the Peptide Cost Calculator to factor in vial price, dose size, and optional supply costs to get cost per dose and cost per mg.

Question 5

How do I model peptide blood levels over time?

Accepted Answer

Enter your peptide's half-life and dosing frequency into the Steady State Calculator to see a chart of serum blood levels accumulating over time and when steady state is reached.
