You need to clean up diet first and remember that is going to be like 90% of your results. Sure, Cardarine will help, but if diet is trash, you will notice no difference.
At 24 you have been running steroids for 2 years already? I would honestly not use them and give your body a break. You are headed down a bad path for health and fertility.
I would focus on cutting down body fat for now. For that, I would recommend GW, SR-9009, and RAD if you want 3 compounds. Check out RCS and Umbrella Labs for the best, legit products.
Nice TD broski! Looking forward to following this one. Very different from most with your setup. Can't wait to see how things go when you switch the compounds up.
I don't think you need to be running more than 50mg per day. It just tends to add more sides that are not worth the little extra progress you might see.
