Reconstitution Guide
Step-by-step: how to properly mix your peptides
About 10 minutes
Why Reconstitution Matters
Peptides ship as lyophilized (freeze-dried) powder because they're unstable in liquid form long-term. You need to reconstitute them with bacteriostatic water before use.
Step 1: Gather Supplies
You'll need:
- Peptide vial (lyophilized powder)
- Bacteriostatic water vial
- Insulin syringe (1mL)
- Alcohol swabs
Step 2: Determine Water Volume
The amount of BAC water you add determines your concentration. A common approach is to add a "round" amount that makes dosing math simple.
Step 3: Clean Everything
Wipe the top of both the peptide vial and BAC water vial with an alcohol swab. Let them air dry for a few seconds. Sterility is critical.
Step 4: Draw Bacteriostatic Water
Using a fresh syringe, draw the desired amount of BAC water. Pull back the plunger to your target volume, insert the needle into the BAC water vial (inverted), and draw slowly.
Step 5: Add Water to Peptide Vial
Insert the syringe into the peptide vial at an angle. Let the water trickle slowly down the side of the vial — do NOT squirt it directly onto the powder cake.
Step 6: Mix Gently
Most peptides will dissolve within a few minutes. You can gently roll the vial between your palms or swirl it slowly. If there are stubborn particles, let the vial sit in the refrigerator — most dissolve on their own within a few hours. If particles or cloudiness persist after that, the product may be compromised — don't use it.
Step 7: Label Your Vial
Write the peptide name, concentration, and reconstitution date on a small label or piece of tape on the vial. This prevents mix-ups and helps track freshness.
