Clenbuterol Profile Excerpt
So Let’s re-examine that first point I made: Clen vs. clen+excercise produce roughly the same results for the first 2 weeks! This tells me that the 2 weeks on and 2 weeks off schedule for clen dosing is far from optimal, and if you want the quasi-anabolic effect from the clen, it’ll take more than 2weeks on (6 weeks apparently). In addition, since clen alone is similar to clen+excercise for those first 2 weeks...why would you ever use a 2on/2off protocol? Keep in mind that animal responses to beta-agonist/antagonists differ a bit from ours…but I’m sure that you get the idea that 2on/2off is not a great dosing protocol. If I were using clen, I’d be using it for 6-12 weeks at a time, if I expected to get maximum results from it...
