What is the difference between a single vial and a 10-pack?
A 10-pack contains ten vials of the selected nominal size, not one vial with ten times the amount. For example, a 20 mg 10-pack contains ten 20 mg vials, totaling 200 mg of nominal labeled material. The comparison shows the total pack price and the calculated price per vial from the same current offer.
How do I match my Retatrutide order to its COA?
Every order has a matching published COA. Match the lot number on the material you receive, along with its size and formulation, to the published batch report. A prior report documents a prior lot; do not assume it describes the current shipment. A Standard report should not be used to verify a Mannitol-Free lot.
How do I choose Standard or Mannitol-Free?
Use the formulation selector with your required vial size, then check that combination’s price, availability and lot documentation. Not every size or pack is offered in both formulations. Mannitol-Free does not automatically mean excipient-free; use the documentation for the specific formulation and lot.
Comparing suppliers? The Retatrutide supplier checklist covers quantities, prices and report matching. Larger-quantity powder is a separate format on the bulk Retatrutide powder page.
Variation and lot documentation
- Vial format: Select from the sizes currently shown on this page
- Standard formulation: Composition and excipients must be stated on the selected variation label or batch record
- Mannitol-Free formulation: Applies only when the selected variation and matching batch record explicitly say Mannitol-Free
- Purity and measured content: See the report for the exact lot and variation supplied
- Other tests: Results apply only to the identified sample and analytes named in the report
- Packs: Confirm that the pack and each unit map to the stated lot documentation
No page-wide purity threshold, additive-free statement, or formulation claim applies across every variation.
