DAVE LEE'S DAILY FOUNDATION
The Foundational Stack
The three supplements I take every day — and the first three I put my clients on. Fully dosed and third-party quality tested.
Why these three
I've coached 3,000+ men through hormone optimization, and the supplement aisle drove me crazy — under-dosed, proprietary blends, no testing. Marek is what I wished existed: clinician-formulated, fully dosed, and third-party tested with COAs you can actually read. These three are part of my own daily routine and the foundation I start almost everyone on.

INDEPENDENTLY VERIFIED
The data behind the stack
I don't put my name on anything I haven't seen the lab work for. Every Marek batch is tested by LC-MS/MS at two independent labs — potency, heavy metals, the works. That's why I'm confident recommending these to my clients, and taking them myself.
