Buy RETA Australia

Buy Reta 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
