This thread is gold. I've been waiting for community testing data on grey market reta before committing. Two questions: 1. Has anyone tried reta from QSC for comparison? I know they listed it recently at $42/10mg vial. 2. Storage stability — reta has the fatty acid moiety that could be more susceptible to oxidation., are you storing unreconstituted vials at -20C or just fridge temp?

I can answer #2 from a biochem perspective. Retatrutide's C20 fatty acid chain is similar to semaglutide's C18 and tirzepatide's C20 fatty acid modifications in terms of oxidation susceptibility. Lyophilized under nitrogen atmosphere, it should be stable at -20C for 12+ months and at 2-8C for 6+ months. Once reconstituted, use within 28 days max, stored at 2-8C. Keep it away from light — the aromatic amino acid residues are photosensitive. Personally I store all unreconstituted vials at -20C in a dedicated mini freezer. Vials in active use go in the fridge after reconstitution.

Just received my WWB reta order yesterday. 3x 10mg vials, $45 each. Ordered Feb 10, arrived March 1 — 19 days to West Coast. Packaging was the same quality as their tirz: vacuum sealed, cold pack, discreet outer packaging. Haven't tested with Janoshik yet but plan to send one vial this week. Will report back. The cakes look good — compact, slightly off-white as OP described, no collapse or discoloration. Going to start at 1mg/week since I'm completely naive to GLP-1 agonists. Might be one of the few people trying reta as their *first* peptide rather than stepping up from tirz or sema.

Starting with reta as your first GLP-1RA is bold. Most people work up from semaglutide. Just be extra cautious with titration — the triple agonism means three receptor systems activating simultaneously. Start low, go slow. Regarding QSC reta: I've seen a couple reports on the Telegram group but no published Janoshik results yet. If someone has QSC reta test data, please share. Would be great to have comparative purity numbers. Quick subjective update at week 3 of 2mg/week: down 6.2 lbs, appetite consistently suppressed, no nausea after the first week. Energy is notably better than when I was on tirz. Whether that's the glucagon component or placebo, I can't say yet. Labs in two weeks.

Compiling a reta tracker spreadsheet for the community. So far I have: | Source | Dose/Vial | Price | Janoshik Purity | Reporter | |--------|-----------|-------|-----------------|----------| | WWB | 10mg | $45 | 97.4% | EndoResFellow | | WWB | 10mg | $45 | 97.1% | EndoResFellow | If anyone gets test results from QSC, GL Biochem, or any other source, DM me or post here. I'll keep the sheet updated. This is probably the most important peptide launch in the grey market since tirzepatide became available, and community-sourced QC data is how we keep each other safe.
