I've been on sema since about mid October of last year. In late January I got really sick, and was off of it for a couple of months. I started back up at the end of March, but started back on .25 since I was starting over. I'm up to .75. Weight is coming off very slowly. I'm thinking about trying tirz, and want to try stacking it with the sema, either to transition from sema to tirz completely or maybe to continue stacking. I'm looking for others' experiences. I like nitty gritty details. How much of each do you use? On what kind of schedule? Do you inject both on the same day or space them out? Thank you!
