Tribex or

I am just coming off a cycle of Nandrosol while doing meltdown training and wanted to know if I could just take Biotest “M” or do I have to use Tribex? The store I buy my supplements from is out of Tribex, but has “M”. I need to know so that if Tribex is the better choice I can order it ASAP. Any help is greatly appreciated.
