The Reconstitution Calculator Just Got Stupid-Simple
I was getting the same questions over and over — in the community, on TikTok, in DMs — about how to reconstitute peptides.
“How much BAC water do I use?” “Where do I draw to on the syringe?” “How do I dose a blend?”
So I rebuilt the calculator on PeptidePrice to make it as simple as humanly possible. If you mess this up, you probably shouldn’t be researching peptides. 😂
How It Works
Step 1: Type in your peptide and the vial size (e.g., BPC 10mg).
Step 2: It auto-fills the BAC water amount using the “add a zero” method — 1mg of peptide = 10 units of BAC water. So 10mg auto-fills to 1mL, 20mg to 2mL, 30mg to 3mL. Above 30mg, it caps at 3mL because that’s all those little vials hold. You can always adjust this manually if you prefer different math.
Step 3: Enter your dose (MCG or MG).
Step 4: Pick your syringe size — 0.3mL, 0.5mL, 1mL insulin syringe, or 3mL peptide pen cartridge.
Hit calculate and it shows you exactly how many units to draw to, with a visual of the syringe. Plus it tells you doses per vial, concentration, volume per dose, and total peptide.
The Blend Calculator Is Where It Really Shines
Select your blend (like the Glow Blend — GHK-Cu 50mg / TB-500 10mg / BPC 10mg), and it auto-fills all the peptide amounts and BAC water for you.
You can dose by total blend OR by individual peptide. So if you want 2mg of GHK-Cu per dose, it’ll calculate exactly how much TB-500 and BPC you’re getting per injection along with it. Doses per vial, total peptide, everything.
What About the Old Calculator?
The advanced calculator is still there for those of you who’ve been using it. This new simplified version just pops up by default now. On mobile, you can find it under Resources → Reconstitution Calculator.
Just wanted to make sure this was accessible for everybody new to the research space.

Appreciate you guys. 🤝

Just a recommendation as I saw it on another calculator where it provided a label that you could simply copy into your label maker. It provided the date, dose and units. Thanks for your “stupid” but really awesome tool. 🤗
