RTA-GLP-3R reconstitution is the lab process of dissolving freeze-dried (lyophilized) RTA-GLP-3R powder in bacteriostatic water to make a solution of known concentration. This guide covers the supplies, choosing the water volume, the mixing steps, a concentration reference table, storage and troubleshooting, for researchers working with research-grade RTA-GLP-3R.

Key takeaways
- RTA-GLP-3R reconstitution = adding bacteriostatic water to lyophilized powder to make a solution of known strength.
- The water volume sets the concentration. More water = weaker solution. The milligrams in the vial never change.
- Round volumes (1 mL or 2 mL into a 10 mg vial) keep the math simple.
- Store reconstituted solution at 2–8 °C, away from light. Never shake; avoid freeze-thaw.
What RTA-GLP-3R Reconstitution Means
- RTA-GLP-3R is supplied as a freeze-dried powder because peptides are far more stable dry.
- Reconstitution dissolves the powder into a solution that can be measured and stored.
- The peptide amount is fixed. Reconstitution only decides how much liquid it is spread across — which sets the concentration.
Supplies Needed
| Item | Role | Note |
|---|---|---|
| Lyophilized RTA-GLP-3R vial | The peptide being dissolved | Keep sealed until mixing |
| Bacteriostatic water | The diluent that dissolves the powder | 0.9% benzyl alcohol preservative |
| Calibrated pipette | Measures and transfers the water | Accuracy here sets every later calculation |
| Alcohol swabs | Clean both vial stoppers before opening | One swab per stopper; let it dry |
Bacteriostatic water is preferred over plain sterile or distilled water because its benzyl alcohol inhibits microbial growth, so a reconstituted solution resists contamination in storage.
Choosing the Water Volume
- Formula: concentration (mg/mL) = peptide in vial (mg) ÷ water added (mL).
- 10 mg vial + 1 mL = 10 mg/mL. Same vial + 2 mL = 5 mg/mL.
- Both still hold 10 mg — only the strength per mL differs.
- Full concentration math: RTA-GLP-3R concentration calculator.
Step-by-Step Mixing
- Swab both stoppers and let them air-dry.
- Measure the chosen volume of bacteriostatic water (for example, 2 mL).
- Add it down the glass wall of the peptide vial — never straight onto the powder.
- Let it dissolve on its own — usually within a minute or two.
- Swirl, don’t shake. Shaking foams the solution and can damage the peptide.
- Inspect. The solution should be clear and particle-free.
- Label it with concentration, date and batch number.
Concentration Reference Table
| Vial size | Water added | Concentration |
|---|---|---|
| 10 mg | 1 mL | 10 mg/mL |
| 10 mg | 2 mL | 5 mg/mL |
| 10 mg | 3 mL | 3.33 mg/mL |
| 10 mg | 4 mL | 2.5 mg/mL |
This table describes solution strength only. Record the volume used — it is the only way the concentration stays known.
Storage After Reconstitution
- Refrigerate at 2–8 °C, away from light.
- Solutions are more fragile than dry powder.
- Refrigerated peptide solutions in this class are generally reported stable for around four weeks.
- Avoid freeze-thaw cycles.

Troubleshooting
- Cloudy or particles: water added onto the powder or the vial was shaken. Add down the glass and swirl gently.
- Foaming: the vial was shaken. Let it settle; the peptide may be damaged.
- Won’t fully dissolve: allow more time and swirl. Do not heat.
- Volume not recorded: the concentration is unknown, so every calculation is unreliable.
- Wrong water: plain sterile or distilled water has no preservative.

Frequently Asked Questions
What water is used for RTA-GLP-3R reconstitution?
Bacteriostatic water is the standard diluent. Its 0.9% benzyl alcohol inhibits microbial growth, so the solution can be stored.
How much water is used for RTA-GLP-3R reconstitution?
There is no single required volume. The water sets the concentration: 1 mL in a 10 mg vial gives 10 mg/mL; 2 mL gives 5 mg/mL.
Should RTA-GLP-3R be shaken during reconstitution?
No. Shaking foams the solution and can damage the peptide. Swirl gently instead.
How should reconstituted RTA-GLP-3R be stored?
Refrigerated at 2–8 °C, away from light, and without freeze-thaw cycles.
Is RTA-GLP-3R FDA-approved?
No. RTA-GLP-3R is investigational and not FDA-approved. It is sold for laboratory research only.
