Waste Prevention
Never waste a milligram again.
Most researchers discard usable peptide because they don't know how many doses remain. Vial Guard calculates exactly how many draws you have left - down to the unit mark on your syringe.
TL;DR - Enter your vial size, BAC water volume, and dose. ASCEND tells you exactly how many doses your vial contains - and what syringe mark each draw should hit.
The Problem
Why peptide gets wasted
Without a dose counter, you're estimating. A typical 10 mg tirzepatide vial reconstituted with 2 mL of BAC water should yield exactly 8 doses at 2.5 mg - but most people draw by feel and discard the remainder when the vial "looks empty."
The average waste: 1–2 doses per vial. At $40–$80 per vial, that's real money discarded every cycle.
The Math
How Vial Guard works
Doses = (Vial mg ÷ Dose mg)
Draw per dose = (BAC water mL ÷ Doses) × 100 (U-100 units/mL)

Example - 10 mg vial + 2 mL BAC water + 2.5 mg dose = 4 doses · Draw to 50 units on a 1 mL (100-unit) syringe each time.
How to use it
3 steps in the calculator
1
Select your peptide or enter custom values. The vial size and BAC water auto-fill from the preset.
2
Set your dose. Use the dose chips for protocol-standard amounts, or type your own.
3
Read "Vial Lasts" in the results panel. It shows total doses and updates live as you adjust any value.
