Peptide Profiles — 2026-11-09
If you've searched for "retatrutide" and landed on products called Reta 10mg and Reta 20mg, you might be wondering whether they're the same compound. They are. "Reta" is simply the common shorthand for retatrutide — the same triple-agonist research peptide, just a shorter name. This quick guide clears up the naming and points you to the right dosing resources.
Researcher special: code SAVE25 or PLATINUM25 unlocks 25% off Reta 10mg and Reta 20mg plus bacteriostatic water. Every vial ships with a batch-matched COA at 99%+ HPLC purity.
Retatrutide = Reta. Same molecule, same research compound. The research community and vendors often abbreviate it to "Reta" the same way tirzepatide becomes "Triz" and semaglutide becomes "Sema." Nothing about the peptide changes — only the name length.
The full compound name is retatrutide; the product name you'll see at checkout is Reta.
Retatrutide is a triple-receptor agonist studied in metabolic and weight-loss research. It targets three systems at once:
This three-pathway mechanism is what separates it from GLP-1-only and dual-agonist compounds. For the full profile, see what is Reta.
| Product | What it is | Reconstitution | Per-unit |
| Reta 10mg | Retatrutide 10 mg | 1 mL bac water | 10 units = 1 mg |
| Reta 20mg | Retatrutide 20 mg | 2 mL bac water | 10 units = 1 mg |
Both deliver 1 mg per 10 units — the 20mg vial just lasts twice as long. The weekly research protocol (titrating 2 → 3 → 4 mg) is the same for both sizes.
So whether you call it retatrutide or Reta, you're looking at the same triple-agonist research peptide — pick the 10mg or 20mg vial based on how long you want a single vial to last.
