I get it from my HRT doc. But understand Im using a doc that only specializes in HRT... through an HRT clinic. So I find that they have more knowledge of what works and how, and thus have more AAS available for you to be able to use.
Here is another example - I get anavar from my HRT doc too. Would a normal doc, even that sometimes scripts test, have var or winnie available? Probably not.
I would cut it out 6 weeks before competing. I think bloat is largly diet related. If I am contest preping even 1000mgs of sust did not bloat me. A slight bit or water retention but not bloated at all...it is all in the diet!
