I often read online "supplements are a waste of money and don't work" - but then I take Tongkat Ali and I spend half the day with raging boner so hard I can feel my heart beating in my dick. The second I stop taking it, lo and behold, back to baseline. Had to stop taking it because I was having to fap at work to kill the 24/7 boners and sexual thoughts. I was entertaining conversations with 6's and 7's that's how horny it made me.

I then also read about how Ashwagandha is fantastic for sleep, stress, etc. I've been through 5-6 of the KSM-66 extract bottles at different doses, timing, etc and feel sweet fuck all.

Creatine gave me headaches. L-Argnine, L-Citrulline, etc. Nothing. ZMA gave me wild, vivid dreams that were unbearable and seriously fucked with my sleep quality. Right into the garbage bin.

What supplements do you take and do you find them beneficial? What are your experiences? How do you determine which supplements are a waste of money, which are beneficial, etc? Is there a point in taking B2, B12, Zinc, etc if you're not deficient?
