Retatrutide Vial: What's Inside a 10mg, 20mg or 30mg Vial

What a retatrutide research vial contains, what 10mg looks like, and how to check a vial against its batch certificate.

The short answer

A retatrutide research vial holds freeze-dried (lyophilised) retatrutide as a white to off-white powder, sealed in glass under a rubber stopper. The "10mg", "20mg" or "30mg" on the label is the stated amount of peptide. It is a mass, not a volume.

What a 10mg vial looks like

Ten milligrams is a very small amount of powder. It can sit as a compact cake at the bottom of the vial or spread as a thin film on the glass, and both are normal for freeze-dried material. A sparse-looking vial is not by itself a sign of a short fill. The certificate and the batch number are what to check, not the volume of powder you can see.

Reading the label against the paperwork

  • •Size. 10mg, 20mg and 30mg are separate catalogue items, each certified as its own batch.
  • •Batch number. It must match the number on the certificate in the COA library.
  • •Form. Lyophilised powder. Pens and ready-made solutions are different products.
  • •Identity and purity. The certificate reports the identity and HPLC purity of that batch. It does not describe any biological effect.

The three single-vial batches (100234, 100235 and 100236) are tabulated on the retatrutide identity page. The guides to reading a peptide COA and understanding HPLC purity explain what the figures can and cannot show.

The bundle kit

The Retatrutide Bundle Kit pairs two 10mg vials with a 3mL vial of bacteriostatic water. The retatrutide in it is the same material as the single 10mg vial. The retatrutide buying guide lists every format, and prices are on the retatrutide price page.

What the vial is not

  • •Not a pen. Pen listings elsewhere are different products from this lyophilised vial.
  • •Not a ready-made solution. The material is supplied dry.
  • •Not a medicine. Retatrutide as supplied here is a laboratory reagent, not a licensed medicine.
