What exactly is Retatrutide, and where does the 40mg tier fit?
Retatrutide is a triple-agonist synthetic peptide at the GLP-1, GIP, and glucagon receptors, studied in pre-clinical metabolic-axis models. The 40mg per vial tier is the high-throughput step on the ladder, suited to studies where a single reconstitution supplies a full week of working stock. All six tiers on the ladder (5, 10, 20, 30, 40, 60 mg) ship as kits of 10 vials or single vials.
What does this specific lot’s CoA cover?
Every RT40-40MG-10V lot ships with a batch-specific certificate: reverse-phase HPLC purity by area and mass-spec identity against theoretical mass. The CoA is not a stability panel — those are separate assays we do not run in-house.
How do I reconstitute a 40mg Retatrutide vial?
- Wipe the vial stopper with an alcohol swab.
- Draw 3 to 4 mL of bacteriostatic water (target working concentration determines exact volume).
- Inject the diluent slowly against the vial wall — do not aim at the peptide cake.
- Swirl gently to dissolve. Do not shake.
- Store the reconstituted vial at 2 to 8 °C. Use within 30 days.
Should I order the 40mg tier, or a different size?
High-throughput tier. Suited to studies where a single reconstitution supplies a full week of working stock. Reduces per-session sterile-technique overhead.
How is Retatrutide different from Tirzepatide?
Tirzepatide is a dual GLP-1 / GIP agonist. Retatrutide adds a third arm at the glucagon receptor. The pre-clinical metabolic-axis literature treats that third activity as the mechanistic distinction between the two molecules.
What ships in the box, and how fast?
- 10 lyophilized Retatrutide 40mg vials
- 1 lot-specific certificate of analysis (HPLC + MS)
- 1 handling and reconstitution insert
