Introduction
Proper peptide reconstitution requires specific supplies to maintain sterility and ensure accurate measurements. Whether setting up a research laboratory or organizing personal research supplies, having the right kit makes the process safer and more reliable.
This guide covers all essential and optional supplies, quality standards, sourcing options, and proper technique for peptide reconstitution.
Core Supplies
1. Bacteriostatic Water
The most critical supply for peptide reconstitution.
| Specification | Requirement |
|---|---|
| Grade | USP |
| Preservative | 0.9% benzyl alcohol |
| Sterility | Verified |
| Container | Multi-dose vial |
| Size | 10mL or 30mL |
Why Bacteriostatic Water:
- Allows multi-use without contamination
- Extends reconstituted peptide stability
- Industry standard for research
- Cost-effective over time
Quantity Planning:
- 1mL-3mL per peptide reconstitution
- 30mL vial services ~10-15 peptides

Reconstitution Protocol
Preparation
- Clean workspace - Wipe down surface with alcohol
- Gather supplies - All items within reach
- Wash hands - Thoroughly before starting
- Check peptide - Verify powder appears normal
Step-by-Step Process
Step 1: Calculate Volume
Determine water volume based on desired concentration:
Common Reconstitution Volumes:
5mg peptide + 1mL water = 5mg/mL (5,000mcg/mL)
5mg peptide + 2mL water = 2.5mg/mL (2,500mcg/mL)
10mg peptide + 2mL water = 5mg/mL (5,000mcg/mL)
Step 2: Sanitize
- Wipe BAC water vial stopper with alcohol swab
- Wipe peptide vial stopper with alcohol swab
- Allow to dry completely (~10 seconds)
Step 3: Draw Water
- Insert needle through BAC water stopper
- Invert vial and draw calculated amount
- Remove air bubbles by tapping syringe
- Verify volume is correct
Step 4: Add to Peptide
- Insert needle through peptide vial stopper
- Critical: Aim water against vial wall
- Depress plunger slowly
- Water should run down wall, not spray powder
- Remove needle
Step 5: Mix Gently
- Do NOT shake
- Gently swirl vial
- Roll between palms if needed
- Allow foam to settle
- Confirm complete dissolution
Step 6: Document
- Label vial with:
- Peptide name
- Concentration (mcg/mL)
- Date reconstituted
- Expiration (28 days typical)
Post-Reconstitution
- Store immediately at 2-8°C
- Use within 2-4 weeks
- Inspect before each use
- Discard if cloudy or contaminated
Storage Solutions
Refrigerator Organization
Recommended Setup:
- Dedicated container/box for peptides
- Away from door (temperature fluctuation)
- Clear labeling
- Temperature log if critical
Temperature Monitoring
| Storage | Temperature | Duration |
|---|---|---|
| Refrigerator | 2-8°C (36-46°F) | 2-4 weeks |
| Freezer | -20°C (-4°F) | 1-3 months |
| Room temp | 15-25°C (59-77°F) | Hours only |
Travel/Transport

| Syringes | Until expiration (usually 3-5 years) |
| Alcohol swabs | Until expiration |
| Needles | Until expiration |
Can I reuse syringes or needles?
No. Never reuse needles or syringes:
- Contamination risk

- Shorter stability (5-7 days refrigerated)
- No preservative protection
- Higher contamination risk
How do I dispose of sharps?
Follow local regulations:
- Use approved sharps container
- Never in regular trash
- Many pharmacies accept sharps
- Medical waste pickup services available
- Some communities have drop-off sites
What size syringe is best?
For most peptides:
- 1mL insulin syringe: Best precision for small volumes
