How To Store Epithalon Properly?

Store Epithalon in a refrigerator at 36 to 46 degrees Fahrenheit (2 to 8 degrees Celsius). Lyophilized (freeze-dried) Epithalon is relatively stable and can tolerate short periods at room temperature, but reconstituted Epithalon must stay refrigerated at all times and should be used within 14 to 21 days.

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) with a relatively simple structure compared to larger peptides. This makes it somewhat more resilient to storage fluctuations, but proper handling still matters to ensure potency and sterility throughout your cycle.

Storing Lyophilized Epithalon

Lyophilized Epithalon is the powder form as it comes from the pharmacy or supplier, before you add bacteriostatic water.

• Temperature: Refrigerate at 36 to 46 degrees F. Some sources indicate that lyophilized Epithalon can remain stable at room temperature for weeks to months, but refrigeration is always the safest choice.
• Light protection: Store in the original vial packaging or wrap in foil. Light exposure can accelerate degradation of peptide bonds over time.
• Moisture: Keep vials sealed. The lyophilized powder is hygroscopic, meaning it can absorb moisture from the air, which initiates degradation even before you intentionally reconstitute.
• Shelf life: Properly stored lyophilized Epithalon can maintain potency for 12 to 24 months. Always check the expiration date on your vial.
• Freezing: While some providers allow freezer storage for long-term holding of lyophilized peptides, avoid repeated freeze-thaw cycles. If you freeze it, thaw once and don't refreeze.

Storing Reconstituted Epithalon

Once you add bacteriostatic water to the powder, the clock starts on a shorter shelf life.

• Temperature: Must be refrigerated at all times. Don't leave at room temperature.
• Shelf life: Use within 14 to 21 days of reconstitution. Some compounders assign shorter or longer beyond-use dates. follow the guidance specific to your product.
• Handling: Swirl gently to dissolve. Never shake the vial. Aggressive agitation can break peptide bonds and reduce effectiveness.
• Sterility: Wipe the vial stopper with an alcohol swab before every draw. Use a new syringe each time. Contamination is the most common cause of premature product spoilage.
• Position: Store vials upright in the refrigerator to keep the stopper area dry.

1. Use bacteriostatic water (not sterile water for injection). Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth and extends the solution's usable life.
2. Add the water slowly along the inside of the vial wall. Don't squirt it directly onto the powder.
3. Allow the powder to dissolve naturally. If needed, swirl very gently.
4. Label the vial with the reconstitution date and the calculated beyond-use date.

Common Storage Mistakes

• Storing in the bathroom: Bathrooms are warm and humid. Keep peptides in the kitchen refrigerator or a dedicated mini fridge.
• Placing too close to the freezer vent: The back of the refrigerator near the cooling element can freeze liquids. Use a middle shelf or door shelf.
• Using past the beyond-use date: Even if the solution looks clear, degraded Epithalon may have reduced or no biological activity.
• Reconstituting too much at once: Only reconstitute what you'll use within the recommended timeframe. Keep extra vials in lyophilized form until needed.
