Reconstitution Tips

Adding Water

Slowly add bacteriostatic water along the side of the vial. Never spray directly onto the powder. Let it dissolve naturally - don't shake.

Storage

Once reconstituted, store in the refrigerator (2-8°C). Most peptides remain stable for 4-6 weeks when properly stored.

Syringe Selection

U-100 syringes are most common. For very small doses, U-50 or U-30 syringes provide better precision with larger unit markings.

Measuring Accuracy

Adding more water makes measuring easier but increases injection volume. Less water = more concentrated = smaller injection.
