RTA-GLP-3R half-life and storage stability are two separate things that often get blended together. Half-life is a pharmacokinetic measure from clinical research — how long the compound persists in circulation. Storage stability is about the vial on the shelf. This page covers both: what the published research reports on half-life, and how the research material is stored in a lab, dry and reconstituted. It’s written for researchers working with research-grade RTA-GLP-3R.
For laboratory research use only. Not for human or veterinary use. Investigational and not FDA-approved. This page summarizes published research and lab handling. It gives no usage guidance.
Key takeaways
- Published pharmacokinetic research reports an RTA-GLP-3R half-life of about 6 days.
- That long half-life comes from a fatty-acid modification that binds albumin.
- Sealed lyophilized (dry) vials are reported stable at −20 °C for up to 24 months.
- Reconstituted solution is refrigerated at 2–8 °C and generally reported stable for about four weeks.
RTA-GLP-3R Half-Life in Research
- Published Phase 2 pharmacokinetic data report a half-life of about 6 days.
- That’s long for a peptide — and it’s by design.
- The molecule carries a C20 fatty diacid chain that binds albumin, a blood protein, slowing clearance.
- In plain terms: the fatty chain works like a life jacket, keeping the peptide from being cleared quickly.
- Half-life is a clinical research measure. It says nothing about how long a vial lasts on the shelf.
Storage at a Glance
| Form | Storage | Reported stability |
|---|---|---|
| Lyophilized (dry), sealed | −20 °C, frozen, dark | Up to 24 months |
| Reconstituted | 2–8 °C, refrigerated, dark | About 4 weeks |
| Working solution on the bench | Back to the fridge promptly | Within the 4-week window |
Storing Dry (Unmixed) Vials
- The sealed dry powder is the most stable form.
- Store at −20 °C, sealed and away from light.
- Short periods cool or at room temperature during shipping are generally tolerated by dry powder.
- Stability drops sharply once water is added.
Storing Reconstituted Solution
- Refrigerate at 2–8 °C.
- Keep it in the middle of the fridge — the door runs warm and the back wall can freeze.
- Don’t freeze reconstituted peptide; freeze-thaw damages it.
- Label with mixing date, concentration and batch.
- Mixing method: RTA-GLP-3R reconstitution.
Why Bacteriostatic Water
- It contains 0.9% benzyl alcohol, a preservative that inhibits microbial growth.
- That suits a solution stored for weeks.
- Plain sterile water has no preservative and suits single use only.

Frequently Asked Questions
What is the half-life of RTA-GLP-3R?
Published Phase 2 pharmacokinetic data report about 6 days, extended by a fatty-acid chain that binds albumin.
How should RTA-GLP-3R be stored?
Sealed dry vials at −20 °C, dark. Reconstituted solution refrigerated at 2–8 °C, away from light, and never frozen.
How long does reconstituted RTA-GLP-3R stay stable?
Generally reported stable for about four weeks when refrigerated at 2–8 °C.
Is half-life the same as shelf life?
No. Half-life is how long the compound persists in circulation in clinical research. Shelf life is how long the vial’s contents stay intact.
Is RTA-GLP-3R FDA-approved?
No. RTA-GLP-3R is investigational and not FDA-approved. Research-grade material is sold for laboratory research only.
Research-Grade RTA-GLP-3R
Project Amino supplies RTA-GLP-3R synthesized in the US and third-party lab tested, with a certificate of analysis per batch. For the full topic library, start from the RTA-GLP-3R research handbook.
