🧫 Reconstitution Guide

1

Prepare Your Environment

Wash hands thoroughly and put on sterile gloves and goggles. Ensure your workspace is clean. You will need: lyophilized peptide vial, sterile syringe, bacteriostatic water, and alcohol swabs.

2

Bring to Room Temperature

Allow both the peptide powder and bacteriostatic water to reach room temperature before reconstituting. Cold solutions can interfere with the reconstitution process.

3

Clean the Vial Tops

Remove the center of the metal cap from the peptide vial. Disinfect the rubber stopper with an alcohol swab. Repeat for the bacteriostatic water vial.

4

Add the Bacteriostatic Water

Using a sterile syringe, carefully withdraw the required amount of bacteriostatic water. Tilt the peptide vial at a 45° angle and slowly inject the water down the interior wall — not directly onto the powder. This minimizes bubbles and ensures even dissolution.

5

Gently Mix — Never Shake

Gently roll the vial between your palms until the powder is fully dissolved. Never shake vigorously — this can degrade the peptide structure and reduce potency.

6

Storage

Store reconstituted peptide solution at +4°C (refrigerator) for short-term use — stable for approximately 3+ weeks. For long-term storage, freeze at -20°C or below in aliquots. Avoid repeated freeze-thaw cycles as these compromise peptide integrity.
