Advanced Testosterone Support

• Shilajit at 500 mg per day matches the dose used in published trials of purified shilajit in men
• Every ingredient amount is disclosed — no proprietary blend and no filler botanicals
• Made by a brand with cGMP compliance, an NSF-certified facility, an A rating from Australia's TGA and four rounds of testing
• Simple two-capsule daily dose; buyers consistently report no taste, no aftertaste and no side effects
• Gluten-free, dairy-free and soy-free per Thorne's own verification
• About $1.43 per serving at list price — steep for a four-ingredient formula
• Ashwagandha at 120 mg is below the 300–600 mg used in most root-extract testosterone trials
• Not NSF Certified for Sport, unlike several other Thorne products
• Human evidence that luteolin meaningfully affects testosterone or aromatase is limited

Zinc Picolinate 15 mg

• 15 mg dose close to the RDA and well under the 40 mg upper limit
• Minimal excipients; gluten-, dairy- and soy-free
• Listed in NSF's certification database; Amazon listing says NSF Contents Certified
• Small 18 mm capsules
• No copper included for long-term use
• Picolinate's absorption advantage is a brand claim NIH does not confirm
• About $0.25 per day, pricier than drugstore zinc
• Two capsules a day plus diet can approach the upper limit
