Tool
Blends Calculator
Calculate dosing for pre-mixed peptide blends or combining separate vials into one syringe.
One vial with multiple peptides already blended. Dose ratios are locked to the blend ratio — you draw once and get all peptides.

How Blend Math Works
Pre-Mixed Blends
When a vial contains multiple peptides already blended together, the dose ratios are locked. You pick the dose for one peptide, and every other peptide's dose is determined by the blend ratio.
- Total blend = sum of all peptide amounts (e.g. 5 mg + 5 mg = 10 mg total)
- Concentration = Total blend (mcg) ÷ BAC water (mL)
- Draw volume = Desired primary dose (mcg) ÷ Primary peptide concentration (mcg/mL)
- Units to draw = Draw volume (mL) × 100
Every other peptide in the blend is delivered at the same proportional draw. If the blend is 50/50 and you dose 100 mcg of peptide A, you automatically get 100 mcg of peptide B.
Separate Vials
When drawing from multiple individual vials into one syringe, each peptide has its own reconstitution math. The calculator sums the total units to ensure you don't exceed syringe capacity (100 units on a U-100 syringe).
- Calculate units for each vial independently (same math as a single reconstitution)
- Draw from vial A first, then vial B, into the same syringe
- Total units = sum of all individual draws
Common Blend Examples
Growth Hormone
CJC-1295 + Ipamorelin
5 mg + 5 mg blend + 2 mL BAC water
- Total concentration: 5,000 mcg/mL
- 100 mcg CJC dose = 4 units
- You also get 100 mcg Ipamorelin
- 50 doses per vial
Recovery
BPC-157 + TB-500
5 mg + 5 mg blend + 2 mL BAC water
- Total concentration: 5,000 mcg/mL
- 250 mcg BPC dose = 10 units
- You also get 250 mcg TB-500
- 20 doses per vial
Triple GH Stack
CJC + Ipa + GHRP-2
3 mg + 3 mg + 3 mg blend + 2 mL BAC water
- Total concentration: 4,500 mcg/mL
- 100 mcg CJC dose = 6.7 units
- You also get 100 mcg of each
- 30 doses per vial
