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.

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
