Sorry.. I am new to this site so if this is repetitive I apologize. I just took advantage of Aminos Research's sale. I am going to try 1mg Oz on Sunday and 2.5 Tirz on Weds and go from there. Thank you so much for responding.I think it was on here that I saw a couple people mention they are using both... And switching to tirz after stalling on Sema seems to be fairly common, and is my plan... Hoping tirz prices come down by the time I get there, though with all this cease and desist crap going on, I fear the prices might actually rise.
