I think this thread is starting to make very obvious that stacking 5000 natural supplements is cost ineffective, stupid, and sets you up for disappointment.
Or at least that's what it looks like to me, haha.
That seems like a fair and accurate assessment. One or two natural supplements (they may have multiple ingredients in them), plus other stuff that isn't taken with the intention of gaining size/strength (pre-workout, multi, fish oil, joint support, etc), should be plenty. After a point you end up at a place where the marginal benefits don't justify the added costs.
For me, most of the time (besides things like vitamins, joint support, nootropics, pre-workouts, etc) I'll only take a supplement that covers my basics (with creatine, betaine, etc) and some lecithin granules as a source of PA. If I'm overreaching, I may add in some HMB, but that's about it (although there are some ingredients that can help with strength/size that I take, but not primarily for those reasons like Ashwagandha, tongkat Ali, and Spirulina).
With that said, there are some supplements that, while adding them to a stack may not result in completely additive gains/progress, can still be of use/benefit, perhaps by improving libido/energy or reducing stress/anxiety (improving the way you feel and general well-being), which can potentially have a carry-over positive effect on your ability to focus on and enjoy what's needed to make progress/gains.
