Description
What is retatrutide?
Retatrutide (LY3437943) is a synthetic triple-receptor agonist peptide that engages the GLP-1, GIP, and glucagon receptors simultaneously — the first “triple G” agonist to advance through late-stage metabolic research. In published phase 2 work it produced some of the largest body-weight reductions ever recorded in a metabolic trial program, which is why retatrutide has become one of the most requested compounds in Canada.
Retatrutide brings three signalling pathways into one molecule: GLP-1 activity for satiety and insulin dynamics, GIP for lipid handling and adipose signalling, and glucagon agonism for energy expenditure. Each 10mg vial is lyophilized for stability and reconstitutes clear with bacteriostatic water.
| Contents | 10 × 10mg vials of retatrutide |
|---|---|
| Form | Lyophilized powder, sterile sealed vial |
| Purity | ≥99% (HPLC verified) |
| Batch | All 10 vials from one production lot |
| Certificate | Third-party COA per batch (request with your batch number) |
| Storage | Sealed: refrigerate 2–8°C; reconstituted: refrigerate and use within recommended timelines |
Reconstitution notes
Reconstitute with bacteriostatic water against the vial wall and swirl gently — never shake a peptide vial. Your order includes a free 10-pack of bacteriostatic water for exactly this purpose.
Why buy retatrutide as a 10-pack
Single-vial retail pricing punishes people who actually use volume. Our 10-pack format works out to $63.00 per vial — up to 30% below typical single-vial retail in Canada — and because every vial ships from one production lot, a single certificate of analysis covers your entire supply. One order, one batch, zero between-vial variance.
Quality & testing
Every lot is independently tested for identity (mass spectrometry) and purity (HPLC) before release. Packs ship cold-packed with tracking from our Canadian facility, and each order automatically includes one free vial of bacteriostatic water.
