How to Reconstitute GLP-3/RT: A Step-by-Step Guide
Reconstituting GLP-3/RT is not identical to reconstituting any other compound in this library. Dissolves readily but behaves like a surfactant, not like a small peptide.
Overview
Add liquid slowly down the vial wall and let it dissolve on its own, which can take a few minutes. Never shake it. A 20 mg vial in 4 mL gives 5 mg/mL. If the solution looks faintly hazy at higher strength, that is normal for this type of molecule.
What GLP-3/RT actually is
GLP-3/RT is an engineered molecule built to act on three receptors at once, all belonging to the system of hormones your gut releases around eating. Getting one chain to fit three different targets well is a genuinely hard design problem, which is why molecules like this appeared years after simpler ones.

Diluent selection for GLP-3/RT
Dissolves readily but behaves like a surfactant, not like a small peptide. The C20 fatty-diacid chain that gives GLP-3/RT 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.
Common reconstitution reference
A 20 mg vial in 4 mL yields 5 mg/mL. Add diluent slowly and swirl — never shake a lipidated peptide.

- 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.
What GLP-3/RT is studied for
The defining feature: simultaneous GIP, GLP-1, and glucagon receptor activity from one chain.
Glucagon-receptor activity is studied for its contribution to energy expenditure, distinguishing triagonists from dual agonists.
Investigated in metabolic research models for effects on glucose homeostasis.
