๐Ÿ“‹ Step-by-Step Instructions

1
Prepare Your Materials

You'll need: peptide vial, bacteriostatic water, alcohol swabs, insulin syringe (1ml with 100 unit markings)

2
Clean the Vial Tops

Wipe the rubber stoppers of both the peptide vial and bacteriostatic water vial with alcohol swabs. Let them air dry for 30 seconds.

3
Draw Bacteriostatic Water

Using a clean syringe, draw of bacteriostatic water from the vial.

4
Add Water to Peptide Vial

Slowly inject the water into the peptide vial. Aim for the side of the vial, not directly onto the powder. This prevents damage to the peptide.

5
Mix Gently

DO NOT SHAKE! Gently swirl the vial in a circular motion until all powder is dissolved (1-2 minutes). The solution should be clear.

6
Store Properly

Immediately refrigerate the reconstituted peptide (2-8ยฐC / 36-46ยฐF). Label with the date and concentration. Use within 30 days.

7
Draw Your Dose

For each injection, draw ( on insulin syringe) from the vial.

โš ๏ธ Important Safety Notes

  • Always use bacteriostatic water, not sterile water (for multi-dose vials)
  • Never shake the vial - this can damage the peptide structure
  • If the solution is cloudy or has particles, do not use it
  • Always refrigerate reconstituted peptides
  • Use within 30 days of reconstitution
  • Rotate injection sites to prevent irritation

๐Ÿ’ก Common Examples

Example 1: BPC-157 (5mg vial, 250mcg dose)

Vial: 5mg (5000mcg)

Target Dose: 250mcg

Add: 2ml bacteriostatic water

Result: 2500 mcg/ml concentration, use 0.1ml (10 units) per dose

Example 2: Semaglutide (5mg vial, 0.5mg dose)

Vial: 5mg

Target Dose: 0.5mg (500mcg)

Add: 2ml bacteriostatic water

Result: 2.5 mg/ml concentration, use 0.2ml (20 units) per dose

Example 3: Large Vial (50mg vial, 2mg dose)

Vial: 50mg

Target Dose: 2mg

Add: 5ml bacteriostatic water

Result: 10 mg/ml concentration, use 0.2ml (20 units) per dose
