Retatrutide is currently the most active area of metabolic peptide research literature , a triple GLP-1/GIP/glucagon receptor agonist that engages three distinct receptor systems in a single molecule. Irish research groups increasingly work with Retatrutide in preclinical models, and reconstitution planning is central to reproducible protocols. This reference sets out reconstitution volumes, working concentrations, and typical research-context protocol windows.
| Diluent added | Working concentration | Volume for common protocol doses |
|---|---|---|
| 1.0 ml bac water | 5 mg/ml (5000 µg/ml) | 200 µg → 40 µl · 500 µg → 100 µl · 1 mg → 200 µl |
| 2.0 ml bac water | 2.5 mg/ml (2500 µg/ml) | 200 µg → 80 µl · 500 µg → 200 µl · 1 mg → 400 µl |
| 2.5 ml bac water | 2.0 mg/ml (2000 µg/ml) | 200 µg → 100 µl · 500 µg → 250 µl · 1 mg → 500 µl |
| 5.0 ml bac water | 1.0 mg/ml (1000 µg/ml) | 200 µg → 200 µl · 500 µg → 500 µl · 1 mg → 1000 µl |
Which volume? Choose the reconstitution volume that gives your working concentration a comfortable pipetting range typically 100–250 µl per protocol dose. Very small volumes (< 25 µl) are harder to measure accurately.
The core formula:
Working concentration (µg/ml) = (mg in vial × 1000) ÷ ml of diluent added
Example: 5 mg Retatrutide + 2.5 ml bacteriostatic water = 2000 µg/ml. To deliver 500 µg, draw 250 µl.
Detail in our reconstitution guide.
Retatrutide reconstituted in bacteriostatic water is stable at 2–8 °C for approximately 2–4 weeks for most research protocols. For studies running longer than 4 weeks, aliquot immediately after reconstitution into single-use portions and freeze at −20 °C to preserve integrity across the study window.
Published preclinical models with Retatrutide typically operate in these concentration windows (research context only these aren’t human dosing recommendations):
Always defer to the specific research protocol you’re running. This reference chart supports reconstitution planning, not protocol design.
