Peptide blends
Free, neutral calculators for popular peptide stacks. Pick a blend to reconstitute each component in its own vial and plan a same-syringe co-draw — with concentration, draw volume, and U-100 units for each. Reference and arithmetic only — not medical advice.

Browse the blend calculators
Each blend page has a working co-draw calculator seeded with that stack, plus the reference status of every component. More blends are on the way.
The classic recovery stack — two repair peptides, reconstituted separately and co-drawn into one syringe.
The GLOW stack plus the anti-inflammatory tripeptide KPV — four peptides, one same-syringe co-draw.
A growth-hormone secretagogue pair — reconstitute each and plan the same-syringe co-draw.
A copper peptide plus two repair peptides, often run together for skin and recovery.
What is a peptide blend co-draw?
A co-draw means reconstituting each peptide in its own vial, then drawing the doses into a single syringe to inject together. It only works when the peptides use the same diluent and compatible pH, and no blended stack is clinically validated. These calculators handle the arithmetic — concentration, draw volume, and U-100 units for each — so you can check the numbers. They do not tell you what to take; that belongs with a qualified professional.
Reference and arithmetic only. Not medical advice; verify with a clinician, product label, pharmacist, or approved research protocol.
Frequently asked questions
What is a peptide blend?
A peptide blend (or ‘stack’) is two or more peptides run together, often for recovery or skin. Popular examples include Wolverine (BPC-157 + TB-500) and GLOW (GHK-Cu + BPC-157 + TB-500). None is FDA-approved as a blend and none is clinically validated.
How do the co-draw calculators work?
Each blend page reconstitutes every component in its own vial and shows the concentration (mg/mL), draw volume, and U-100 syringe units for each, plus the combined draw. It is arithmetic only — enter your own vial size, water, and dose.
Which blends are covered?
Right now, Wolverine (BPC-157 + TB-500) and GLOW (GHK-Cu + BPC-157 + TB-500). More are being added, and you can build any custom stack in the blend planner on either page.
Do these pages recommend any blend?
No. They are neutral references that reflect the limited information available, and they do not assess the safety, efficacy, or suitability of any blend. Consult a qualified professional.
