Reconstituting peptides sounds intimidating but takes less than two minutes once you've done it a couple times. Here's the complete process.

What You Need
- Lyophilized (freeze-dried) peptide vial
- Bacteriostatic water (BAC water) — 30mL vial
- Insulin syringe (1mL / 100 unit)
- Alcohol swabs
Step 1: Calculate Your Reconstitution Volume
Decide how much BAC water to add. Common approach: 1–2mL per vial. Example: 5mg peptide + 1mL BAC water = 5mg/mL = 500mcg per 0.1mL drawn.
Step 2: Clean Both Vial Tops
Wipe the rubber septum of both vials with an alcohol swab. Let dry for 10 seconds.
Step 3: Draw BAC Water
Using an insulin syringe, draw the desired amount of BAC water.
Step 4: Add to Peptide Vial
Insert the needle through the septum of the peptide vial. Aim the stream at the glass wall — not directly at the powder. This prevents foaming and degradation. Push the plunger slowly.
Step 5: Mix Gently
Never shake a reconstituted peptide. Swirl gently until the powder fully dissolves. The solution should be clear.
Step 6: Store Properly
Label the vial with the reconstitution date and refrigerate. Most reconstituted peptides are stable for 4–6 weeks at 36–46°F.
Keep Your Vials Organized
Once you're running a full protocol, a dedicated storage case makes a big difference. Browse VialLock cases — sized from 2 to 100 vials, starting at $6.
