YOUR DOSAGE
Quick Steps
- 1.Add 1ml BAC water to vial
- 2.Draw to 5 units
- 3.This = 250mcg dose
- 4.Store in fridge at 4°C
Storage & Handling
Before: Store at -20°C to -80°C
After: Refrigerate at 4°C (4-6 weeks)
Best Practices
- ✓Use bacteriostatic water
- ✓Swirl gently, never shake
- ✓Use insulin syringes
- ✓Create aliquots for storage
Avoid These Mistakes
- ×Using non-sterile water
- ×Shaking vial aggressively
- ×Room temp storage
- ×Repeated freeze-thaw
Reconstitution Tips
Solvent: BAC water for most peptides
Technique: Add dropwise to side of vial
Guide & FAQ
How to Use the Peptide Calculator
Enter Your Syringe Details
Select your syringe volume (0.3ml, 0.5ml, or 1ml) and total units (30, 50, or 100 units). Most insulin syringes are clearly marked.
Enter Peptide Vial Information
Input the peptide quantity in your vial (e.g., 5mg) and how much bacteriostatic water you added (e.g., 2ml). Check your vial label for the peptide amount.
Specify Your Desired Dose
Enter the dose you want to inject (e.g., 250mcg). The calculator will show you exactly how many units to draw.

Common Peptide Dosage Calculations
BPC-157 Dosage Calculation
Typical dose: 250-500mcg daily. Use our calculator to determine units for your 5mg vial reconstituted with 2ml bacteriostatic water.
Semaglutide Dosage Calculation
Starting dose: 0.25mg (250mcg) weekly. Calculate exact units for precise dosing as you titrate up.
TB-500 Dosage Calculation
Loading phase: 5-10mg twice weekly. Calculate units for your 10mg vial to ensure accurate loading doses.
Frequently Asked Questions
How do I calculate peptide dosage?
Enter your syringe volume, total units on syringe, peptide vial quantity (mg), amount of bacteriostatic water added (ml), and your desired dose (mcg). The calculator will show you exactly how many units to draw.
How much bacteriostatic water should I add to my peptide?
Common amounts are 1ml or 2ml. Using more water makes it easier to measure small doses accurately. The calculator works with any amount you choose.
What size insulin syringe should I use?
The most common sizes are 0.3ml (30 units), 0.5ml (50 units), and 1ml (100 units). Smaller syringes provide more precise measurements for small doses.
How long does reconstituted peptide last?
When properly stored in the refrigerator at 4°C, reconstituted peptides typically last 4-6 weeks. Some peptides may have shorter or longer stability periods.
Can I freeze reconstituted peptide?
Yes, you can freeze aliquots at -20°C for longer storage. However, avoid repeated freeze-thaw cycles as this can degrade the peptide.
