Every human is different. What works for one person may have a totally different effect on the next guy. For myself, 3 caps of beast made me quite lethargic. I had to quit @ week 3 (although in fairness I probably would have quit anyway due to being hit by a ton of stuff at work). Under normal circumstances I probably would have finished the regimen, but I just couldn't handle fatigue given what was going on in my life. On the other hand, I did 3 caps of dieselbolan 2.0 + 2 caps of Epi ED (probably not recommended) and I absolutely loved it. I got no bad sides on that regimen and had better gains really. I didn't gain as much strength as quickly, but I had better muscle growth and the gains didn't go away at all after PTC. I read a lot of people on here who say that beastdrol does not make them lethargic, and I believe them. Every person is different.
Bottom line, try stuff and see what works for you. If the stuff isn't working, do something else. I don't plan on doing a full regimen of beast again, but am ordering more diesel. I will finish the beast I have though by doing at the end of some other cycle. Waste not/ want not.
