BSN supplements, graded by the human studies
We graded 2 BSN products against the human studies of their ingredients, the dose on each label and what buyers say in their reviews. Each grade belongs to the product and the goal it was graded for: we do not grade how BSN makes, tests or sells its products, and we sell no supplements. Educational, not medical advice.

Questions people ask
Members Only
Is BSN a good brand?
We grade products, not brands, and we sell none. Of the 2 BSN products we graded, 2 are Tier 4 (Emerging). None is top-ranked for its goal yet. Each product's grade, the studies behind it and its label are on its own page.
Which BSN products have the strongest evidence?
By our grades: Syntha-6 Edge Chocolate Milkshake (Tier 4, graded for muscle and strength); Clean BCAAs Watermelon (Tier 4, graded for muscle and strength). A product's grade is for the goal it was graded for, at the dose on its label.
How does Reverse Age Lab grade BSN products?
Each product is graded for a goal on the human studies of its ingredients at the dose on its label, what buyers say in their reviews and what our panel of ten biohackers has said. The grade belongs to the product. We do not grade how BSN makes, tests or sells its products, and we are not affiliated with BSN.
Can I take BSN supplements with my meds?
Some supplements can interact with meds. Members have every product checked against the meds in their Health Profile before it joins their protocol.
Educational, not medical advice. Grades come from human studies on PubMed, the dose on each label, store reviews we read ourselves and our biohacker panel, and are updated as new studies arrive. BSN is a trademark of its owner; Reverse Age Lab is not affiliated with it and sells no supplements. How we grade →
