I think you are both right and wrong...
Right - barely anything too special about their pills, i.e., timed release, different formulations for male and female and CaAKG. They say the tested hundreds of formulations. What goals (that they can prove) about 'longevity' were met? The mammals they refer to often are mice, not people. $200/bottle sounds ridiculous to me. Perhaps the old sales ploy i.e., 'the more expensive the better the product must be', works for them. I'm a sceptic.
Wrong (maybe) - Tom Weldon of Ponce de Leon Health > https://www.linkedin...ncedeleonhealth has an intriguing resume. He hold holds a B.S. in Industrial Engineering from Purdue University and an M.B.A. in Operations and Systems Management from Indiana University. He's achieved many things and monetized much of it, it seems. That helps his chances for being successful doing whatever significantly.
With a nice website and words some other formula might be successful or not. As recent erratic stock and crypto prices have shown us, something's value is simply what's someone will pay for it, not much else. There are other longevity formulations already. A good question, has Rejuvant (or would something similar on the market) been a monetary success? I do not know, could be worth a shot.
