Creatine vs. the "test booster" aisle.

Creatine: rated Strong

Creatine monohydrate is the most-studied sports supplement in existence, with hundreds of trials supporting modest but real gains in strength, power, and training volume. It's cheap, it's safe for healthy adults, and the effective dose is simple: about 5 g/day. In Hitt Fitness it carries our highest rating, labeled ✓ Peer-reviewed

"Test boosters": rated Unproven

Testosterone-booster blends promise the world from a mix of herbs, vitamins, and minerals. For men with normal levels, the claims are largely unsupported — most ingredients show no meaningful effect on testosterone or performance in controlled studies. The occasional component (like correcting a real zinc or vitamin D deficiency) has an effect, but that's a deficiency fix, not a "boost."

That's why a product like "Test Blast" lands in our Unproven tier. We'd rather tell you the truth than sell you hope.

How the rating scale works

• Strong — robust, replicated evidence (e.g., creatine).
• Moderate — reasonable support, some caveats (e.g., omega-3, certain probiotics).
• Weak — mixed or thin evidence; food usually does it better.
• Unproven — claims not supported by quality research.

The point

A supplement aisle is designed to make everything look equally credible. Hitt Fitness un-flattens that by scoring each product on the strength of its science — and pointing you to food when that's the smarter buy.
