GLP-1 / Weight Management

Retatrutide Peptide Calculator

Use the Retatrutide peptide calculator below to determine your reconstitution and dosing. A triple agonist targeting GLP-1, GIP, and glucagon receptors simultaneously. In Phase 3 trials. Early results showed up to 24% body weight loss, making it potentially the most effective weight loss peptide.

Retatrutide Quick Reference

Typical Dose

500 mcg - 12 mg

Frequency

1x per week

Route

Subcutaneous injection

Half-Life

~6 days

Common Vials

5 mg, 10 mg

Reconstituted Stability

Up to 28 days refrigerated

Note: Still in clinical trials. Titration is essential -- start at 0.5 mg/week and increase gradually. The triple agonist mechanism produces stronger weight loss but potentially more GI side effects than dual or single agonists.

Retatrutide Storage

Lyophilized: 2-8 C. Reconstituted: 2-8 C

Stability after reconstitution: Up to 28 days refrigerated. Always use bacteriostatic water for multi-use reconstitution. Label the vial with the reconstitution date and discard after the stability period. Use our peptide calculator above to determine the right amount of water to add.

Retatrutide Frequently Asked Questions

Retatrutide (LY3437943) is a triple-receptor agonist that targets GLP-1, GIP, and glucagon receptors. It is currently in Phase 3 clinical trials and has shown up to 24% body weight reduction in early studies.

Based on clinical trial protocols: start at 0.5 mg/week for 4 weeks, increase to 2 mg for 4 weeks, then 4 mg for 4 weeks, then 8 mg for 4 weeks, and finally 12 mg for maintenance.

Retatrutide is a triple agonist (GLP-1 + GIP + glucagon) while tirzepatide is a dual agonist (GLP-1 + GIP). The added glucagon receptor activity may provide additional metabolic benefits including enhanced fat oxidation.

Add 2 mL bacteriostatic water for 2.5 mg/mL. For 0.5 mg, draw 0.2 mL (20 units). For 2 mg, draw 0.8 mL (80 units).

As of 2024, retatrutide is NOT FDA approved. It is in Phase 3 clinical trials conducted by Eli Lilly. Approval timeline is estimated for 2025-2026 pending trial results.

Similar to other GLP-1 agonists: nausea, diarrhea, vomiting, and decreased appetite. The triple mechanism may intensify GI effects compared to single or dual agonists, making slow titration essential.
