Peptide Blend Calculator

For a vial that holds more than one peptide. Dose by one of them, and see how much of every other compound comes along in the same draw.

Peptides in the vial

Blends have a locked ratio.

Setting the dose for one peptide fixes how much of every other peptide you get. You cannot dose them independently once they share a vial.

What this calculator does

Some vials hold two, three, or four peptides mixed together, like a BPC-157 and TB-500 blend. Because they share the same liquid, you cannot set each dose on its own. The moment you decide how much of one peptide to draw, the amounts of the others are already fixed by their ratio in the vial. This calculator makes that trade-off visible.

Enter each peptide and its milligrams, the water you reconstituted with, and which peptide your target dose is measured by. The result is the units to draw for that peptide, plus a line for every other compound showing exactly how many micrograms come along in the same shot.

Reading the result

The main number is the draw for your chosen peptide. The per-injection list is the important part of a blend: it shows what else you are taking at that draw, so you can check whether the ride-along amounts land where you want. If they do not, the only levers are the target dose or the ratio you mix at. The math assumes an evenly mixed vial; it does not judge whether the combination is stable or safe to run together.

Common questions

How do you dose a peptide blend?
You pick one peptide as your anchor and dose to that. Once two or more peptides share a vial, their ratio is locked, so every draw pulls all of them in the same proportion. Set your target for the main peptide, say BPC-157, and the others come along at whatever ratio they were mixed in.
Can you mix BPC-157 and TB-500 in one vial?
Yes, plenty of people reconstitute both in the same vial, and pre-mixed versions are sold as a single product. The tradeoff is you lose independent control. Mix 5 mg of each and every draw gives them 1:1, so you cannot dial one up without the other coming with it.
Why can I not dose each peptide in a blend separately?
Because they are in the same solution. A syringe pulls liquid, not individual peptides, so whatever ratio they were mixed at is the ratio in every single draw. If you need different amounts on different days, keep the peptides in separate vials.
What is a GLOW or KLOW blend?
GLOW is usually GHK-Cu, BPC-157, and TB-500 mixed together, and KLOW adds KPV. They get used for skin, hair, and recovery. Since the ratio is fixed, you dose to one peptide and accept the others at their set proportion, which is exactly what a blend calculator shows you.
Is it safe to blend peptides in one vial?
Mixing compatible peptides in bacteriostatic water is common and generally fine for storage, but blending does not make them safer or stronger than dosing each on its own. The real risk is the peptides themselves, not the fact they share a vial. If you are unsure two compounds belong together, keep them apart and check with your provider.
