The BBC piece looks at how the hype around the new weight loss drug retatrutide is driving a market of counterfeit versions, with users reporting inconsistent dosing and nasty side effects. It stresses that even when people think they’re getting the real thing, the actual amount can vary wildly, making any self‑experiment risky.

Anecdotally, I’ve seen similar issues with research peptides where a batch that seemed fine one month caused unexpected gut upset the next, and third‑party lab tests later showed low purity. This reinforces my habit of asking for a certificate of analysis and doing a small tolerance test before committing to a full protocol, especially for anything I’m injecting or taking orally.

How do others here verify the legitimacy of their peptides? Have you ever caught a fake through bloodwork or noticeable side‑effects, and what steps do you now take to avoid it?
