Buy RETATRUITIDE
Buy Retatruitide Australia (LY3437943) is a triple GLP-1/GIP/glucagon agonist developed by Eli Lilly. It’s still in Phase 3 clinical trials, making it the most potent weight loss peptide available that has no FDA-approved prescription version yet. Phase 2 trials showed average weight loss of ~24% at 48 weeks, higher than semaglutide (~15%) or tirzepatide (~22%). The only way to access it currently is via research peptide vendors.
Where to Buy Retatrutide, Our Top Pick
Ascension Peptides is our primary recommendation:
- Carries R-10 (10mg, $120) and R-30 (30mg, $200)
- US-based manufacturing
- Third-party COA on every batch, HPLC purity ≥98%
- Mass spectrometry verification (critical for a complex triple agonist)
- Discreet US domestic shipping
Red Flags to Avoid; Buy Reta Australia
- ❌ No COA or COA only “available on request”
- ❌ Purity not listed, or listed as “≥95%” without HPLC documentation
- ❌ Dramatically underpriced (R-30 for $60 = almost certainly underdosed)
- ❌ Ships from overseas with no US warehouse
- ❌ No mass spectrometry data (especially important for retatrutide)
- ❌ Generic product photos with no lot number information
