What is in this vial
All 2 brands of Retatrutide here come in the same 20 mg vial, so the choice between them is a choice of manufacturer and price, not of quantity. The powder has no concentration of its own: it is set when you add the water. This vial with 2 ml of bacteriostatic water gives 10 mg per millilitre, and with twice that volume, half as much.
The conversion of an amount into insulin syringe units is worked through in the guide on syringe units, and the rules that change once the powder is dissolved are in storage.
Bio-Peptide as the manufacturer
Bio-Peptide has the widest catalogue of the three brands we stock: it is the only one supplying glutathione, NAD+, GHK-Cu, MOTS-C, SLU-PP-332 and semaglutide, so an order from this manufacturer can usually be filled from one supplier. Every vial carries a code under the hologram and a batch certificate, and how to check both is described on the verification page.
What the evidence says
TRIUMPH-1 gave 25.0 percent weight reduction at 12 mg after 80 weeks, and 30.3 percent at 104 weeks in the subgroup with a body mass index of 35 or above. The full account, with the sources and the limits, is on the Retatrutide page, and the background in the guide on the retatrutide phase 3 programme.
We publish no dosing schedules. Sold as research material, not as a medicine.
Retatrutide has finished phase 3 trials and is approved nowhere, which is an unusual combination: more published human data behind it than most of this catalogue, and no regulator’s decision. Bio-Peptide and Genheal both fill 20 mg, against a highest trial dose of 12 mg per week.
Concentration in this vial
| Water added | Concentration | Per unit on a U-100 syringe |
|---|---|---|
| 1 ml | 20 mg/ml | 200 mcg |
| 2 ml | 10 mg/ml | 100 mcg |
| 5 ml | 4 mg/ml | 40 mcg |
The table is arithmetic and nothing else: it converts the 20 mg in this vial into the concentration you get for a chosen volume of bacteriostatic water. It is not a dosing recommendation, and we publish none.
This vial next to the other Retatrutide vials
The same compound is sold here in one other version: Genheal, 20 mg. The molecule is identical in each; what differs is the manufacturer and the amount in the vial. All 2 hold the same amount, so the choice here is the manufacturer and its batch certificate, not the size.
Also from Bio-Peptide in this group
Within Weight loss peptides, Bio-Peptide also supplies MOTS-c 10 mg, Semaglutide 3 mg and SLU-PP-332 5 mg.
