You shouldn't do an oral only cycle, as you will end up lacking testosterone, which means during the back end of the cycle, when your test starts running dry, you'll feel crappy.
But lots of people start that way, and I did too last year, because I was being a pussy about pinning. I did 50mg a day for 7 weeks. I did gain quite a lot of strength, and a bit of size, but I certainly felt run down towards the end of the cycle.
Lots of people will say you don't need to PCT off a var only course, but I did. Tamoxifen, 20mg a day, for three weeks. My nuts came back quickly, and I retained the majority of my gains.
Now I've actually started pinning though and realise how easy it actually is and how it isn't as big a deal as I made it out to be in my head, I wouldn't do an oral-only course again. Pinning is safer and gives more results all-round, and I wished I'd listened to people and plucked up the courage first time round, I'd be further along than I am now.
Just my 2 cents. Best of luck if you do go through with it.
