Cycle 3: Tren + Winny. Advise plz?

[Juiced Up]

Hey, so I just started my 3rd cycle which includes 50mg tabs of Winny everyday for 6 weeks and 600mg Tren injections. My first cycle was winny 350mg/wk x 6 weeks; followed by Tren 200mg/wk x 3 wks and Tren 400mg/wk x 3 weeks. I didn't cycle off between 1 & 2, but I took 2 weeks off between cycle 2 & 3 which was horrible. Had horrible headaches, muscle pain/weakness in right arm, and almost all my results were lost (mainly bc holiday food and lack of exercise).

So....
1) is my cycling schedule safe and optimal towards gaining lean muscle and cutting?
2) are the symptoms I endured while being off normal and how can they be avoided?
