Common questions about Retatrutide
Is Pepdor's Retatrutide independently tested?
Yes. Beyond the batch-verification HPLC COA on every batch, 3 independent third-party lab tests are published unedited in the public Test Ledger. Results are posted as received, whatever they show.
What purity is the current Retatrutide batch?
Current batch RT-2606-A (COA Jun 12, 2026) measured 99.4% by batch-verification HPLC, with independent third-party tests averaging 99.3%. Full history for every batch, including archived ones, stays public.
What documentation ships with Retatrutide?
Every vial carries its batch number and links to a published COA (batch-verification HPLC; LC-MS identity, endotoxin, and sterility shown per batch where tested). 5 mg: $49 per vial; 10 mg: $89 per vial. Sourced direct from the synthesis facility.
How do I verify a Retatrutide batch before ordering?
Every vial label carries its batch number (currently RT-2606-A). Look the batch up in the public Test Ledger or the machine-readable feed at pepdor.com/ledger.json to see the COA and all independent test results before ordering.
How should Retatrutide be stored?
Lyophilized material: store as stated on the batch record. Solution stability depends on solvent, concentration, and laboratory handling conditions; see batch documentation where available.
