How do I calculate the correct peptide dose?

Enter your vial size (mg), bacteriostatic water volume (mL), and desired dose into the ASCEND calculator. It instantly returns the exact syringe draw in IU units, concentration in mg/mL, and volume per dose in mL — no manual math required.

Is the reconstitution math verified for accuracy?

Yes. ASCEND calculation logic is cross-referenced against multiple independent 3rd-party analytical laboratory batch reports and published clinical trial data to ensure research accuracy.

What is bacteriostatic water and why is it used for peptide reconstitution?

Bacteriostatic water (BAC water) contains 0.9% benzyl alcohol, which inhibits bacterial growth and allows multi-dose use of a reconstituted vial. It is the standard diluent for research peptides because sterile water lacks preservative properties and degrades peptides faster after opening.

How many doses are in a peptide vial?

It depends on your vial size, reconstitution volume, and dose. Use the ASCEND Vial Lasts calculator — enter your vial mg, BAC water mL, and dose to see exactly how many doses your vial contains.
