TL;DR
Retatrutide is a triple agonist (GLP-1 / GIP / glucagon receptor) and reconstitutes the same way as tirzepatide — BAC water, gentle swirl, U-100 insulin syringe. Trial protocols titrated weekly subcutaneous doses from 2 mg upward. Total prep time: about 5 minutes.
What you'll need (materials)
- Vial of retatrutide from Noki Labs (5 mg or 10 mg lyophilised)
- Bacteriostatic water (0.9% benzyl alcohol, sterile)
- Insulin syringes — 31G, 0.5 mL (U-100), half-unit markings recommended
- Alcohol swabs (70% isopropyl)
- Sharps container compliant with DOH disposal guidance
Total time required
Reconstitution: ~5 minutes. Each weekly injection: ~2 minutes.
Step-by-step protocol
- Step 1 — Bring the vial to room temperature. Take the retatrutide vial out of the fridge and let it sit for 5–10 minutes before opening.
- Step 2 — Sanitise both stoppers. Wipe the rubber stopper of the retatrutide vial and the BAC water vial with alcohol swabs.
- Step 3 — Calculate BAC water volume. A common ratio is 2 mL BAC water per 10 mg vial — yielding 5 mg/mL, so 0.4 mL = 2 mg. Confirm the math your clinician approved.
- Step 4 — Draw BAC water. Pull the agreed volume into your insulin syringe and tap out air bubbles.
- Step 5 — Add BAC water against the vial wall. Tilt the vial 45° and let the water run slowly down the inside; never aim at the powder pellet.
- Step 6 — Swirl gently. Roll the vial in your palm for ~30 seconds until the solution turns clear. Never shake — shearing damages the molecule.
- Step 7 — Draw your dose. Re-sanitise the stopper, invert the vial, draw your titrated volume, tap out bubbles, and recheck.
- Step 8 — Inject subcutaneously and log. Pinch a fresh abdominal or thigh site, inject at 90°, dispose of the syringe, and log dose, time, site.
Typical reference dosing range
Phase-2 studies titrated weekly subcutaneous retatrutide from 2 mg upward to 4, 8, or 12 mg in 4-week increments to manage GI tolerability. Higher arms in the trials reached 12 mg. Always consult a licensed Philippine medical professional before applying a schedule — see the retatrutide Philippines pillar for full trial summaries.
Storage after reconstitution
Refrigerate at 2–8 °C, upright, away from light. Use within 28 days. Do not freeze. For shipping or transport, follow our cold-chain handling guide.
Common mistakes to avoid
- Shaking instead of swirling.
- Using sterile water for multi-dose protocols (no preservative).
- Forgetting the dose log — critical for titration safety.
- Reusing syringes — always one syringe per injection.
- Skipping room-temperature warm-up before injecting.
FAQ
Q: How is retatrutide different from tirzepatide? Retatrutide is a triple agonist (GLP-1 + GIP + glucagon), tirzepatide is a dual agonist (GLP-1 + GIP). Compare on our tirzepatide vs retatrutide page.
Q: What gauge syringe is best? 31G or 32G insulin syringes minimise discomfort for thin-fluid subcutaneous reference dosing.
Q: Can I split a dose across two days? Trial protocols dosed once weekly. Any deviation should be discussed with your clinician.
Q: Are there cold-chain risks during Philippine shipping? Yes — always check ice-pack integrity on arrival. Our Manila hub ships with thermal packs.
