Enter your vial size.
The calculator works with your exact vial and a clean, common water amount.
Step 1
MIX IT RIGHT, THE FIRST TIME
Reconstitution without the panic.
How much water? Did it foam? Is it cloudy? Did I ruin the vial? PRTCL walks you through mixing your peptide the right way and shows you exactly what your dose becomes.
Name the fear
"Did I ruin my vial?" is the most common first-timer question there is.
Real people, mid-panic: "I just reconstituted for the first time and I think I might've messed up... It foamed up. Think it's still fine, or did I mess it up?" And: "Now I'm concerned that the potency might be affected." That knot in your stomach is normal. Let us untie it.
"I'm a bit lost when it comes to all the reconstitution processes. Is there a good resource available that outlines the dosage and reconstitution instructions?"
The confusion
Nobody agrees on how much water to add, and that is the whole problem.
One beginner asked the question everyone has: "If a vial lists X mg total, how do you determine how much bacteriostatic water to add? Why do people use different volumes of BAC water?" The internet gives ten different answers. The math gives you one clear one, matched to your vial.
The promise
Know how much water to add, and what each unit becomes.
Enter your vial into the free calculator on this site and see what each mark on your syringe is now worth. The full PRTCL app goes further: how to add the water without foaming, what a little cloudiness does or does not mean, and a step-by-step mixing walkthrough with pictures - so the "did I ruin it?" question never comes up.
How it works
Three steps. No guesswork.
Follow the mixing steps.
Aim the water down the side of the glass. Let it dissolve. Do not shake.
Step 2
See your dose math.
The calculator shows what each unit on your syringe now equals.
Step 3
Take a breath
Most "did I ruin it?" moments end with "it was fine all along."
A little foam usually settles. Slight cloudiness is often normal while it dissolves. PRTCL tells you what actually matters and what you can stop worrying about.
