Depends what you want out of them. No natural anabolic is going to put lots of visible muscle on but certain things can help in an auxiliary fashion.
Want help increasing appetite and digestion? Look into K1ngslayer. I also notice increased fullness, recovery, and training performance.
Increased work capacity so you can push the training volume and recover better during and after training? Epicatechin works well for that in my experience so something like Epiplex or Ep1logue (added benefit of Vaso-6 and UroB) are good options.
More of a bodybuilding style training and your joints are solid? Look into SNS X-gels/ArA. Good stuff but the soreness and inflammation can be a little tough on some.
I’m also a big fan of PeakO2. If you train with a decent pace, do circuits, etc the recovery and ability to push time to exhaustion are pretty beneficial and noticeable.
Otherwise make sure you are taking the basics like creatine, eating well, and training hard and yuh should be good to go.
