Reviewed claims

Start with a recently tracked claim.

Fat LossReviewed Jul 16, 2026

A 3,500-calorie deficit always produces exactly one pound of fat loss.

Verdict

The 3,500-calorie rule is a rough planning shortcut, not an exact prediction of one pound of fat loss.

RecoveryReviewed Jul 16, 2026

A wearable recovery score accurately tells you whether you should train.

Verdict

No wearable score can perfectly decide whether you should train. Algorithms estimate sleep and readiness and can miss individual context.

SupplementsReviewed Jul 4, 2026

AOD-9604 burns fat without the downsides of dieting or medication.

Verdict

AOD-9604 fat-loss claims are ahead of the evidence. Animal and mechanism data do not prove reliable human body-composition results, and FDA product-identity/safety concerns plus anti-doping caveats make it high-caution territory rather than a normal supplement shortcut.

Fat LossReviewed Jun 25, 2026

Berberine is a natural Ozempic that produces medication-like fat loss without medical tradeoffs.

Verdict

Berberine is not natural Ozempic. It may have modest weight-related signals in some trials, but that is not medication-like fat loss, prescription-care replacement, or proof that a retail supplement is safe for every person.

SupplementsReviewed Jun 29, 2026

Bovine colostrum boosts immunity, gut health, muscle recovery, and performance for lifters and runners.

Verdict

Bovine colostrum has some interesting athlete illness and gut-barrier research, but it is not proven as a general recovery, muscle, or immunity upgrade. The claim needs exact outcome, population, dose/form, product-quality, milk-allergy, and cost checks.

SupplementsReviewed Jul 4, 2026

BPC-157 heals injuries, tendons, joints, and gut problems safely and quickly.

Verdict

BPC-157 is not proven as a safe injury-healing shortcut. The strongest claims lean on animal or mechanism data, while human evidence is small and weak, and the better human proof would need specific injury outcomes, adverse-event reporting, product-quality controls, and follow-up.

RunningReviewed Jul 27, 2026

Carbon-plated running shoes guarantee faster race times, protect runners from injury, and are safe for regular training.

Verdict

Carbon-plated shoes are not fake, but they are not magic either. The evidence supports a small average running-economy advantage, not guaranteed PRs, injury protection, daily-use safety, or a reason to ignore training and pain signals.

SupplementsReviewed Jul 4, 2026

CJC-1295 and ipamorelin safely boost growth hormone for fat loss, muscle, sleep, and anti-aging.

Verdict

CJC-1295 + ipamorelin marketing turns growth-hormone marker effects into promises about fat loss, muscle, sleep, recovery, and anti-aging. The public evidence does not justify that leap; exact-product outcome trials, safety reporting, product-quality controls, and sport-rule checks are still missing.

Fat LossReviewed Jul 16, 2026

Cold plunges activate brown fat enough to cause meaningful weight loss.

Verdict

Cold exposure can affect thermoregulation, but current evidence does not support cold plunges as a meaningful weight-loss method.

Strength TrainingReviewed Jul 16, 2026

Compound exercises are all you need for strength and muscle.

Verdict

Not for every goal. Compound lifts are efficient, but isolation and machine work can add targeted stimulus with less systemic fatigue.
