Depending on your cycle, or course... There are those products on the market where aPCT may not be enough PCT for you. For the vast majority, it will be. However, those products which may be considered 'clones' of sorts (we all know what they are), your PCT may consist of something a bit stronger, harder to find, and usually by prescription only.
Other than that, I don't think you'll find a better AI on the market than 6-bromo! What are you thinking of cycling? Perhaps we can be of some assistance?
