Reconstitution manual

Six-step technical reference for organizing hygiene, dilution, dissolution, loading, and storage under authorized supervision.

Procedure

Clinical reconstitution and administration manual

Hygiene preparation

Clean the work area carefully. Wash your hands with antiseptic soap and water. Use a swab with 70% isopropyl alcohol to disinfect the rubber tops of the dry peptide vial and bacteriostatic-water vial.

Water withdrawal

Use a sterile reconstitution syringe to withdraw the precise bacteriostatic-water volume, typically 1.0 to 3.0 mL. First inject an equivalent volume of air into the water vial to facilitate withdrawal.

Careful dilution

Insert the needle into the peptide vial at a 45° angle. Inject the bacteriostatic water slowly and gently, directing it toward the glass wall of the vial rather than directly onto the powder. This reduces physical impact on the peptide chains.

Dissolution

Do not shake or agitate the vial vigorously. Instead, roll it gently between your palms. Let the vial rest in the refrigerator for a few minutes until the liquid is clear and free of visible clumps.

Dose loading

Insert the sterile insulin syringe into the reconstituted vial. Invert the vial and introduce air before gently drawing the plunger to load the calculated amount. Remove air bubbles by tapping the syringe lightly.

Subcutaneous injection

Administration is subcutaneous in abdominal fat, thigh, or the back of the upper arm. Disinfect the skin, gently pinch the area, insert the needle at 90°, and administer slowly. Dispose of the syringe in an appropriate sharps container.

Storage

Before reconstitution: keep lyophilized powder refrigerated at 2°C to 8°C. After reconstitution: keep refrigerated and do not freeze the mixed peptide.

Cold chain

Protect the vial from direct sunlight. Document date, batch, and storage conditions; evaluate disposal of the reconstituted vial according to applicable technical documentation.

Contraindications and alerts

Stop use and consult a professional in the event of severe persistent abdominal pain, continuous vomiting, or signs of severe dehydration. This material does not replace clinical assessment.
