Product Reviews

A kitchen-sink herbal focus supplement combining many cognitive-support botanicals and nutrients. Some individual ingredients (Bacopa, huperzine A) have supporting data, but the proprietary blend itself is not clinically validated.

One of America's best-known brain supplements for ~20 years. Essentially a multivitamin blended with common nootropic add-ins (DMAE, bacopa, ginkgo, phosphatidylserine). Popular and inexpensive, but the cognitive ingredients are under-dosed and clinical evidence for measurable benefit is thin.

An oral 'HGH releaser' built on amino acids (arginine, glutamine, ornithine) claimed to prompt natural growth-hormone production as a safer alternative to injections. Evidence is weak: amino-acid secretagogues need very high doses to affect HGH, and no rigorous data support this product's claims.

An inexpensive OTC herbal-and-amino-acid nootropic blend built around St. John's Wort, DMAE and botanical extracts. Affordable and widely sold, but relies on a modest proprietary blend with limited clinical backing at the doses used. St. John's Wort also carries notable drug-interaction risk.

A prescription central-nervous-system stimulant of mixed amphetamine salts approved for ADHD and narcolepsy. Strongly evidence-backed for its indications but carries abuse, dependence and cardiovascular risks; not a supplement.

A proprietary-blend nootropic originally founded by Tim Ferriss (2001), later sold and rebranded as BodyQUICK. Uses undisclosed-dose ingredients like vinpocetine and huperzine A; lacks clinical validation and reviews are mixed.

GH-3 is the same procaine-based Gerovital H3 formula developed by Ana Aslan and promoted as an anti-aging treatment since the 1950s. Its main active is the local anesthetic procaine. Scientific review found no proven benefit, and the FDA bans its importation into the US.

IQ 150 is a nootropic from SomaLife, a company focused on age management and brain health, positioned as an all-natural memory, focus and clarity aid. Marketing emphasizes a transparent (non-proprietary) formula, but detailed public ingredient dosing, pricing and independent efficacy data are sparse.

FDA-approved Schedule IV wakefulness agent and the best-evidenced pharmaceutical cognitive enhancer. Reliably boosts alertness and attention with relatively low abuse potential versus classic stimulants. Prescription-only; off-label 'smart drug' use is common but should be medically supervised.

Sun Pharma's generic 200 mg modafinil, one of the most popular international modafinil brands. Pharmacologically identical to Provigil at a fraction of the cost. Prescription drug in most countries; commonly bought via overseas online vendors, which carries legal and quality-control caveats.
