Where to get supplements?

Hi there, I recently experienced a big crash after a period of pretty decent improvement. I don’t know what’s triggered it, though since taking Vitamin E recently to try and help, my situation has gotten worse (I’m not blaming it, as I’m not sure if it’s just a coincidence since I was already feeling worse before I took it.) But I’ve been looking for some more serious treatments, like HCG or some genuine testosterone therapy as a means to stimulate androgen production. However I live in the UK and these things are essentially impossible to find without a prescription, and my doctor doesn’t believe my condition is anything beyond psychological, so there’s no chance there. I was wondering if anyone had any links or new of anywhere I could find these sorts of things?
