I have been told by someone that the new batch of excelsior is crazy strong so that sounds promising. Although at the moment I am avoiding any strong stimulants. I had a very short break and since then have been using My Protein's Alpha preworkout. I bought it because it was on a massive sale and it looked basic but effective and I am a big fan of their preworkout+ product and this is no different. I am sure the break helped but I am really liking it (possible top 10). I have always responded well to a mix of Citrulline and AAKG and My protein's products always feel strong considering they are just caffeine based. I haven't even been dosing a full 2 scoops either (just over 1.5) but I will start soon.
