Retatrutide Reconstitution Calculator
For in vitro research use only · Not medical advice
Preset to a 20 mg Retatrutide vial in 4 mL of diluent. A 20 mg vial in 4 mL yields 5 mg/mL. Add diluent slowly and swirl — never shake a lipidated peptide.
Retatrutide reconstitution
Preset to a common Retatrutide vial size and diluent volume. Adjust any field for your own laboratory protocol.
A 20 mg Retatrutide vial reconstituted with 4 mL gives 5 mg/mL. Measuring 0.400 mL gives 2,000 mcg per portion — about 10 portions from the vial.
Choosing a diluent for Retatrutide
Dissolves readily but behaves like a surfactant, not like a small peptide. The C20 fatty-diacid chain that gives retatrutide its extended half-life is amphiphilic, so the molecule self-associates and readily generates foam. Solutions may look faintly opalescent at higher concentrations from micelle formation — this is normal for lipidated peptides and is not the same as precipitation.
Handling notes for Retatrutide
- Never shake. Foam on a lipidated peptide solution is denatured material at the air–liquid interface, not a cosmetic issue.
- Introduce diluent slowly down the vial wall and allow the cake to dissolve without agitation, which may take several minutes.
- Do not freeze reconstituted solution — aggregation from freeze–thaw is irreversible.
- Faint opalescence at high concentration is expected; visible particulate is not.
After reconstitution
USP-grade sterile bacteriostatic water, 10 mL multi-use vial.
