Peptide Storage Guide
Temperature, light, and handling requirements for lyophilized and reconstituted research peptide compounds. Proper storage is critical to maintaining purity and potency.
Lyophilized (Dry Powder) Storage
All Alpha Tides research compounds are shipped as lyophilized (freeze-dried) powder. In this state, peptides are at their most stable and have the longest shelf life. Proper storage of lyophilized compounds:
| Condition | Requirement | Notes |
|---|---|---|
| Temperature | 2–8°C (refrigerated) | Room temp acceptable for short-term shipping; refrigerate on receipt |
| Light | Away from direct light | Keep in original vial or amber container |
| Humidity | Low humidity environment | Do not store near sinks or in humid areas |
| Shelf Life | 12–24+ months | Varies by compound; check COA for specific guidance |
| Freeze | Acceptable for long-term | Use −20°C freezer for storage beyond 12 months |
Reconstituted Solution Storage
Once a peptide has been reconstituted with bacteriostatic water, its stability decreases significantly. Reconstituted solutions must be handled and stored carefully to maintain integrity.
| Condition | Requirement | Notes |
|---|---|---|
| Temperature | 2–8°C (refrigerated) | Do not leave at room temperature for extended periods |
| Freezing | Do NOT freeze | Ice crystal formation can denature the peptide |
| Light | Protect from light | Wrap in foil or store in a dark refrigerator compartment |
| Shelf Life | 28–60 days typical | BAC water extends this vs. sterile water |
| Contamination | Use sterile technique | Always swab stopper before each draw |
Freezing a reconstituted peptide solution can cause ice crystal formation that physically damages the peptide structure, reducing potency and purity. Always store reconstituted vials refrigerated at 2–8°C — never in the freezer.
Compound-Specific Storage Notes
| Compound | Lyophilized | Reconstituted | Special Notes |
|---|---|---|---|
| BPC-157 | Refrigerated, up to 24 mo | Refrigerated, up to 60 days | Relatively stable; avoid repeated freeze-thaw |
| Tesamorelin | Refrigerated, up to 24 mo | Refrigerated, up to 28 days | Sensitive to temperature fluctuations |
| GLP-3RT | Refrigerated, up to 24 mo | Refrigerated, up to 30 days | Long half-life does not equal long storage stability |
| GLU-600 | Refrigerated, up to 24 mo | Refrigerated, up to 28 days | Store away from light |
| GLOW | Refrigerated, up to 24 mo | Refrigerated, up to 28 days | Multi-compound blend; follow most sensitive component |
Handling Best Practices
Minimize Temperature Swings
Avoid repeatedly removing vials from refrigeration. Thermal cycling degrades peptides faster than stable storage at slightly elevated temperatures.
Always Swab Before Drawing
Wipe the rubber stopper with a fresh 70% isopropyl alcohol swab before every needle insertion. Allow to dry before piercing.
Label Every Vial
Mark each reconstituted vial with the compound name, concentration (mcg/mL), reconstitution date, and researcher initials. Discard any vial without a legible label.
Inspect Before Use
Check the reconstituted solution for clarity before every use. Cloudiness, particles, or discoloration may indicate contamination or degradation — discard and reconstitute a fresh vial.
