Peptide Blend Calculators
Multi-peptide protocols with step-by-step guides written for complete beginners — equipment lists, reconstitution walkthroughs, and injection instructions for every combination.
BPC-157 + TB-500
Healing & Recovery
The most popular healing stack — two complementary peptides that accelerate tissue repair, reduce inflammation, and support tendon, muscle, and ligament recovery.
CJC-1295 + Ipamorelin
Growth Hormone Optimization
The most studied GH peptide combination — activating two separate pituitary pathways simultaneously for synergistic growth hormone pulses 5–10× larger than either peptide alone.
Semaglutide + BPC-157
Weight Management + GI Support
Semaglutide for weight management paired with BPC-157 to support gastrointestinal comfort and tissue health during the dose escalation phase.
Sermorelin + Ipamorelin
Sleep-Timed GH Optimization
A nightly pre-sleep stack combining a GHRH analog and a selective GHRP to amplify the body's natural nocturnal growth hormone surge.
CJC-1295 + Ipamorelin + BPC-157
Body Composition + Recovery
Three peptides, three complementary mechanisms — GH axis optimization, tissue repair, and angiogenesis combined into one comprehensive research protocol.
How to Use These Calculators
Each peptide calculator uses the same underlying reconstitution formula and outputs both mL volume and IU units for use with standard U100 insulin syringes.
Enter Vial Size
The total milligrams of peptide lyophilized in the vial (e.g. 5 mg). This is printed on the vial label.
Enter BAC Water Volume
The amount of bacteriostatic water you added to the vial (in mL). This determines the concentration of the resulting solution.
Enter Desired Dose
Your target dose in micrograms (mcg). Remember: 1 mg = 1,000 mcg. Use the dose preset buttons on each peptide page for common research protocol doses.
Reconstitution Reference Table
Concentration per 0.01 mL (1 IU) based on vial size and BAC water volume.
| Vial Size | + 2 mL water | + 5 mL water | + 10 mL water |
|---|---|---|---|
| 2 mg | 100 mcg / 1 IU | 40 mcg / 1 IU | 20 mcg / 1 IU |
| 5 mg | 250 mcg / 1 IU | 100 mcg / 1 IU | 50 mcg / 1 IU |
| 10 mg | 500 mcg / 1 IU | 200 mcg / 1 IU | 100 mcg / 1 IU |
Reading a U100 Insulin Syringe
- 1 IU= 0.01 mL
- 10 IU= 0.10 mL
- 25 IU= 0.25 mL
- 50 IU= 0.50 mL
- 100 IU= 1.00 mL (full syringe)
Reconstitution Tips
- 1.Wipe the vial septum with an alcohol swab before each needle insertion.
- 2.Inject BAC water slowly down the side of the vial — never directly onto the powder.
- 3.Gently swirl (do not shake) until the powder fully dissolves.
- 4.Store reconstituted peptides at 2–8 °C. Use within 28 days.
- 5.Label vials with the reconstitution date and peptide name.
