New to Peptides · Part 3: Putting it together

Hype or evidence? Five red flags

Lesson 12.3.1 · 5 min read · Free lesson

1. "Cures everything"

Peptides are talked about a lot online. Some of what you'll read is careful, and a lot of it isn't. Here are five warning signs to watch for. Each one comes from FDA and NIH advice on spotting health claims you can't trust.

When one product is said to fix many unrelated problems, be careful. The FDA lists "one product does it all" as a classic sign of a health scam 12.

2. "Miracle," "breakthrough," "secret"

Big words that promise quick, dramatic results are another FDA warning sign 1. Real research usually sounds cautious.

3. Personal stories instead of studies

"It changed my life" is a story, not a study. People can feel better for many reasons, including the placebo effect, which means feeling better because you expect to 4. Only a fair test with a comparison group can show whether something works 8.

4. Someone is selling it

Ask who benefits. Influencers must clearly say when they are paid or given free products, but many don't 3. If the person making the claim sells the product or earns a commission, weigh their words with that in mind.

5. "For research use only" with health claims

A vial labeled "not for human use" that is marketed for weight loss or healing is a contradiction. The FDA has sent warning letters to sellers doing exactly this 7. Also look out for "FDA approved" claims you can't check. You can look up any approved drug on the FDA's own website 5.

A quick habit

Before believing a claim, ask: who is saying it, what is their evidence, and what does it look like on the traffic light from Part 1 6?
