I not going to flame you for really not knowing why an oral only cycle is bad. However, with as much research as you claim to have done this is one of the simplest questions to have answered opn your own. With that being said, the first cycle I ever did (2.5 years ago) was a D-Bol only cycle with only 150 tabs for 5 weeks. I was scared of needles and a steroid rookie. I used a pyramid type dosing cycle (Hey I was new and didn't know better) starting with two tabs ED and increasing every week (3ED the next, then 5ED for two weeks and going back down). I even had some left over. Anyways, I ate like a pig trained like an animal and made fantastic strength gains and put on like 35 pounds. After the cycle I kept damn near all the strength and lost probably 8-10 pounds. The bloat is killer but you feel like a star. Thats just my experience and I'm sure others with have their own opinion. But build the knowledge base and experiment bro everyone's a little different. Just don't go stupid....you are manipulating the only body you have in this lifetime.
