Retatrutide 24mg
Novel triple-hormone receptor agonist studied for metabolic regulation and body weight reduction via GLP-1, GIP, and glucagon pathways.
Mechanism
Simultaneously activates GLP-1, GIP, and glucagon receptors to orchestrate insulin release, suppress appetite, and enhance lipid oxidation and energy expenditure.
Dosing
Standard investigational protocols initiate dosing at 2 mg injected subcutaneously once every 7 days.
Reconstitution
Reconstitute the 24 mg vial using 2.4 mL of bacteriostatic water to create a stock concentration of 10 mg/mL.
Storage
Keep lyophilized vials frozen at -20 °C or lower, and store the reconstituted peptide solution refrigerated at 2–8 °C away from light for up to 4 weeks.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–4 | 2 mg once weekly | 20 units (0.20 mL) |
| Weeks 5–8 | 4 mg once weekly | 40 units (0.40 mL) |

Reconstitution Steps
- 1
Aspirate 2.4 mL of bacteriostatic water into a sterile syringe.
- 2
Introduce the diluent slowly against the inner glass wall of the vial to minimize turbulent agitation and foaming.
- 3
Gently rotate or swirl the vial until the lyophilized cake is fully dissolved without vigorous shaking.
- 4
Label the vial with the preparation date and place in refrigerated storage at 2–8 °C shielded from light.
Supplies Needed

Overview
Retatrutide represents an emerging class of multi-receptor metabolic peptides designed to mimic and activate several endocrine pathways simultaneously. By co-targeting the glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors, it facilitates complex metabolic signaling beyond conventional mono- or dual-incretin mimetics. In preclinical and clinical research, this multi-pathway agonism has demonstrated substantial influence on nutrient metabolism, insulin secretion, and appetite centers in the central nervous system. Additionally, the activation of glucagon receptors encourages thermogenic activity and lipid oxidation, leading to deeper metabolic alterations. This 24 mg lyophilized presentation is typically employed in extended laboratory protocols where incremental titration curves require a higher vial capacity to sustain multi-week regimens efficiently while minimizing batch variance.
