Blend vial · two peptides, one draw

Peptide blend calculator

One vial holding two peptides is not two vials. They share the water, so a single draw carries both, at a ratio that was fixed before you bought it. Put in your vial and see what a draw holds.

Nothing to work out yet. Enter how much of at least one peptide you want. The tool will show the draw, and what the other peptide does at that draw.

Arithmetic, not a dose. This works out what a draw from your vial contains. It does not say what amount to use, and it is not medical advice. CJC-1295: Trials gave 30 to 60 mcg, in the units and route they used. Ipamorelin: Trials gave 0.03 to 0.06 mg, in the units and route they used.

The link keeps this vial, syringe and both amounts so the same result opens again.

Educational math, not medical advice — dosing decisions belong to a licensed clinician. No amount on this page is a recommendation.

Why you cannot just run a calculator twice

This is the mistake the tool above exists to catch. A single-compound calculator takes a dose and gives you a volume. Run it twice and you have two volumes, chosen freely. A blend vial does not let you choose freely.

There is one plunger. Pull it to any mark and both peptides come out together, in whatever proportion the vial was filled at. Set the syringe for the first peptide and the second is already decided. You never get to pick it.

Adding water does not help, and this is the part that surprises people. Water weakens both peptides by the same factor. A weaker mix means a longer draw for the same amount of the first peptide, and that longer draw carries proportionally more of the second. The ratio survives every mixing volume you can pick. It is a property of the vial, not of the mix.

So two wanted amounts can only both be met when they happen to sit in the same ratio the vial holds. When they do not, there is no draw that gives both, and the tool above shows you the two draws you can actually take instead of averaging them into one number that serves neither.

What each of these vials locks you into

Three blend vials people search for by name. Below, each one is asked for the amount each compound’s own page carries — the figure its own calculator opens on. Those two amounts are not a schedule for the pair, and nothing has tested these pairs in people. They are here to show what a fixed ratio does to two numbers that were never chosen together.

CJC-1295 and Ipamorelin — 5 mg plus 5 mg

Fixed at 1 to 1. In 3 mL of water, one U-100 unit carries 16.7 mcg of CJC-1295 and 16.7 mcg of Ipamorelin.

Ask this vial for 200 mcg of CJC-1295 and 300 mcg of Ipamorelin:

Set by CJC-1295, the draw is 12.0 units and it brings 200 mcg of Ipamorelin — less than the 300 asked for.

Set by Ipamorelin instead and the draw is 18.0 units, which brings 300 mcg of CJC-1295.

No draw between them gives both. The vial is short of Ipamorelin for this pair of amounts.

CJC-1295
Trials gave 30 to 60 mcg, in the units and route they used.
Ipamorelin
Trials gave 0.03 to 0.06 mg, in the units and route they used.

What has and has not been tested for CJC-1295 and Ipamorelin

BPC-157 and TB-500 — 10 mg plus 10 mg

Fixed at 1 to 1. In 3 mL of water, one U-100 unit carries 33.3 mcg of BPC-157 and 33.3 mcg of TB-500.

Ask this vial for 250 mcg of BPC-157 and 1,000 mcg of TB-500:

Set by BPC-157, the draw is 7.5 units and it brings 250 mcg of TB-500 — less than the 1,000 asked for.

Set by TB-500 instead and the draw is 30.0 units, which brings 1,000 mcg of BPC-157.

No draw between them gives both. The vial is short of TB-500 for this pair of amounts.

BPC-157
200 to 500 mcg is a reported range, not a dose anybody established.
TB-500
No published human dose. Nothing sets an amount for this one.

Tesamorelin and Ipamorelin — 10 mg plus 5 mg

Fixed at 2 to 1. In 3 mL of water, one U-100 unit carries 33.3 mcg of Tesamorelin and 16.7 mcg of Ipamorelin.

Ask this vial for 1,400 mcg of Tesamorelin and 300 mcg of Ipamorelin:

Set by Tesamorelin, the draw is 42.0 units and it brings 700 mcg of Ipamorelin — more than the 300 asked for.

Set by Ipamorelin instead and the draw is 18.0 units, which brings 600 mcg of Tesamorelin.

No draw between them gives both. The vial is short of Tesamorelin for this pair of amounts.

Tesamorelin
An approved label sets 1.4 to 1.4 mg, for one use it names.
Ipamorelin
Trials gave 0.03 to 0.06 mg, in the units and route they used.

What this tool does not tell you

It does not tell you what to take. It works out what a draw contains, which is division, and division is true whatever the evidence says. Whether either peptide should go in at all is a different question that arithmetic cannot answer.

For two of the three vials above, at least one half has no dose anybody established. Where that is the case the panel says so beside that peptide’s half of the answer, and the link under each vial explains what has actually been studied.

No trial has given any of these three pairs to a person. That is not a hedge — it is the result of searches you can re-run in one click, and each combination page ships the query, the live link and the date.
