Consumer advice
If you're interested in Tongkat Ali, look for a product that clearly states the mg per capsule and confirms it uses a standardized water extract (like Physta® or LJ100®). The clinically studied dose is 200 mg/day of standardized root extract. Double Wood is a reputable brand, but verify the per-capsule dose before buying. You can find equivalent or identical LJ100 extract products for less — check iHerb or Amazon for NOW Foods or Nootropics Depot versions. Do not use if you have heart conditions, liver disease, or are on medications without consulting a doctor first (case reports of atrial flutter and liver injury exist).
