im on a tbol cycle and its ok. like i love the stuff the first 2 weeks i felt great!!! i gained 10 lbs the first 2 weeks ... strength was threw the roof.. and after the first 2 weeks i started having stomach aches, depression, high blood pressure, chest pains, im still goin on with the cycle but i havnt gained any weight after the first 2 weeks im like almost on the 3rd week if i dont gain anything by week for im cutting the 8 week cycle down to 4. to many sides compared to gains. and libido went down i cant get it up, and im shut down pretty bad as well. but i do look a lot better vascular, leaner, lower Bf% so all the weight i gained the first 2 weeks is muscle. or lean mass.
