A+ science, B-grade reality. The example that proves the system: we grade what you buy and inject, not just the trial.
Verdict, B · Viable
The science is A+, FDA-approved, unimpeachable. But the way you’ll actually source it (gray-market counterfeit risk) and tolerate it (boxed thyroid warning, GI burden, lean-mass loss) is a B. We grade what you buy and inject, not just the trial.
Overview
Tirzepatide is a dual GIP/GLP-1 receptor agonist with unimpeachable, FDA-approved clinical evidence (SURMOUNT-1, n=2,539). Yet the way a buyer actually sources it (gray-market counterfeit risk) and tolerates it (boxed thyroid C-cell warning, GI burden, lean-mass loss) is materially harder than the trial data alone implies.
