Peptide Blend Calculator
Two or more peptides in one vial. We pick the limiting component and tell you exactly how much of each you'll deliver per draw.
🧬 Peptide Blend Calculator
Two or more peptides reconstituted in the same vial. We pick the limiting component so you never under-dose the one that matters most — and tell you exactly how much of each you'll actually receive.
Per-injection delivered dose
Blends share one volume per draw, so the limiting component sets the volume — others may be dosed slightly above target. Adjust mg-in-vial ratios to balance.
Frequently asked questions
What is a peptide blend?+
A blend is two or more peptides reconstituted together in a single vial — typically because they're commonly stacked (CJC-1295 + Ipamorelin, BPC-157 + TB-500). One injection delivers both compounds, but it also means each draw shares the same volume.
Why do other calculators get blends wrong?+
Most tools treat each peptide independently and tell you to draw a different volume for each. In a blend, you can only draw one volume per injection. Our calculator picks the 'limiting' component — the one that needs the largest volume to hit its target dose — and shows you how much of every other component you'll actually receive.
How do I balance a blend so each component lands on its target?+
Adjust the mg-in-vial ratio. For CJC-1295/Ipamorelin at a 1:2 dose ratio (100 mcg / 200 mcg), a 5 mg / 10 mg vial blend draws cleanly. Use the live 'delivered dose' panel to dial it in.
Are CJC-1295 and Ipamorelin compatible in one vial?+
Yes — they are commonly co-formulated. Standard advice is to refrigerate the reconstituted blend and use within 4 weeks. Always verify storage and stability with your source's COA.
