Is Shilajit worth it?
Shilajit has a small purified-extract testosterone signal, but the evidence base is too thin to justify the hormone-booster hype. The safety issue is not theoretical: mineral-heavy Ayurvedic products have a documented contamination problem, so raw resin and untested imports are the wrong category to gamble on. Skip it unless a clinician is supervising a tested purified product for a specific reason.
The call
A randomized trial of a purified shilajit preparation reported hormone changes in healthy men, and a separate sports study suggests a possible fatigue or strength signal. Those are interesting early findings, but they are small, product-specific, and do not establish a broad testosterone, libido, or energy claim for the retail category. The contamination issue changes the risk math: NCCIH and JAMA-linked evidence show that some Ayurvedic preparations can contain toxic metals such as lead, mercury, or arsenic. A thin benefit signal plus a real quality-control hazard produces a can't-tell verdict and a skip role.
Safety
Do not use raw, unpurified, or untested shilajit; only third-party heavy-metal tested products are even eligible for consideration. Avoid during pregnancy, breastfeeding, in children, with kidney disease, liver disease, hemochromatosis or high iron, gout or high uric acid, hormone-sensitive cancers, prostate/testicular symptoms, infertility evaluation, or unexplained hormone abnormalities. Use caution with diabetes drugs, blood-pressure drugs, anticoagulants, hormone therapies, and stimulant-heavy stacks. Stop for rash, wheezing, severe gastrointestinal symptoms, dark urine, jaundice, neurologic symptoms, palpitations, or signs of metal exposure such as abdominal pain, weakness, numbness, or cognitive changes.
Dose that matters: -; no validated testosterone or energy dose for general buyers. Human trials commonly use purified shilajit around 250 mg twice daily for short periods, but that protocol is product-specific and should not be copied with raw resin or unverified marketplace products.
