Try looking into 19-andro. It looks good for what your talking about. If you want to up your athleticism you might also want to consider at test base. Most go with epi-andro, 4-andro, or Demacrine based on what kind of results they are looking for. Ostarine in my opinion is very weak and is for light in between cycles or maybe help in pct. if you wanted to add a sarm then s-4 would give you strength and dryer muscle plus a pump. There is also a compound called gw which is non hormonal which helps burn fat and enhances endurance but it isn’t very strong in my opinion is if money is not a problem think about it or maybe consider it for pct. the pct is super important so you don’t loose your gains so do your research and think about support supplements for that time. I talked about a variety of compounds, i am not saying take all of them at the same time, just wanted to throw out some options. Most cycles of Sarms and/or prohormones last about 2-3 months. Lastly if you did want to gain some mass lgd is a sarm which is one of the stronger but still safe ones (yk-11 and s-23 being the big boy ones) this sarm gives strength and helps put on size and isn’t liver toxic. Be careful about liver toxicity a lot of prohormones can mess your liver up. Lastly if you want to use Sarms soon or in the future start stocking up because they won’t be around for much longer
