Before You Click 'Add to Cart': 7 Warning Signs a Supplement Seller Is Playing You

We've been in this space long enough to know: the supplement industry contains some genuinely great products and an alarming number of glorified flour capsules. The FDA doesn't pre-approve supplements the way it does drugs, which means the burden of vetting falls squarely on you, the buyer.

So consider this your pre-purchase inspection. Seven red flags, ranked roughly by how fast they should make you close the tab.

Red Flag #1: Proprietary Blends Hiding the Dose

If a label says something like "Testo-Max Matrix — 1,200mg" followed by a list of twelve ingredients, that's a proprietary blend. It's technically legal under FDA rules, but it lets manufacturers list an ingredient without disclosing whether you're getting a clinically studied dose or a dusting of it.

Ashwagandha, for example, shows benefits in research at around 300–600mg of a standardized extract. If it's buried at position #9 in a blend, you're probably getting a fraction of that. The fix: buy products with fully disclosed doses per ingredient.

Red Flag #2: No Third-Party Testing

Anyone can claim their product contains what the label says. Independent verification — NSF Certified for Sport, Informed Choice, USP — means an outside lab actually checked. If a company can't produce a Certificate of Analysis (CoA) when asked, that silence tells you everything.

Red Flag #3: "Contains SARMs" or Mystery "Research Chemicals"

This one's a health issue, not just a wallet issue. Some black- or gray-market sellers dress up unapproved compounds — SARMs, prohormones, designer steroids — as "legal alternatives." The FDA has repeatedly warned that many of these products contain unlisted, potentially harmful substances. If a product's marketing leans on phrases like "stronger than steroids" or "100% legal Dianabol," walk away. That's not a supplement. That's an undisclosed drug with a label problem.

Red Flag #4: A Trail of FDA Warning Letters

Here's a trick most shoppers don't know: the FDA publishes warning letters, and they're searchable. Type a company's name into the FDA's database and see what comes up. A warning letter about claims like "cures" or "treats disease" doesn't automatically make a product dangerous — but a pattern of them tells you how a company views the rules.

Red Flag #5: Before-and-After Photos That Look Too Good

Physique transformation photos are the oldest con in the game. Lighting, pump, dehydration, angles, and — let's be honest — sometimes Photoshop do the heavy lifting. If a company's evidence is a photo grid instead of actual ingredient research, they're selling you a fantasy, not a formula.

Red Flag #6: Miracle Timelines and Disease Claims

"Sheds 20 pounds in 2 weeks." "Reverses low T in 7 days." "Replaces your prescription." Real physiological change takes time, and under US law, supplements legally cannot claim to treat, cure, or prevent any disease. If the copy reads like a pharmaceutical ad, the company is either ignorant of the law or ignoring it — neither is a great sign about what's in the bottle.

Red Flag #7: No Address, No Phone, No Humans

Scroll to the footer. Is there a physical US address? A phone number? A real returns policy? Anonymous companies with only a contact form are easy to find and hard to hold accountable. If something goes wrong — a reaction, a billing issue, a product that never ships — you want a company you can actually reach.

Your 60-Second Pre-Purchase Checklist

Before you buy any supplement, run it through this:

• ✅ Full ingredient list with disclosed doses?
• ✅ Third-party certification or downloadable CoA?
• ✅ No claims to cure, treat, or replace medication?
• ✅ Clean or explainable FDA record?
• ✅ Real company contact info and return policy?
• ✅ Reviews from sources other than the company's own site?

Six checks, one minute, far fewer regrets.

Why We're Pedantic About This

We built Everest Steroids around a simple idea: people who train hard deserve honest information. That means telling you when the research on an ingredient is thin, when a dose is underdosed, and when a product on the market is straight-up sketchy. The mountain metaphor works here too — the fastest routes up are usually the ones that look too good to be true, and they're the ones that leave climbers stranded.

Buy smart, verify everything, and spend your supplement budget on products that respect you enough to show their work.
