I think that is a horrible cycle routine. How did you do back when you did testosterone only cycles?
400mg of Test, 300 deca and 20mg of Dbol
Why do you think that is a horrible cycle? It looks pretty good to me. Some people with pre existing issues can not cope with fluctations in hormones. Doesn't matter what they take. Many things actually increase dopamine levels, thus, increasing happiness when on cycle.
Although if your going through depression and are prescribed something such as an SSRI (like most are) anything that increases dopamine can have a detrimental effect due to the interrelationship between serotonin and dopamine.
Our bodies need a fine balance so any fluctations can cause issues. So many are only concerned with the physical effects of AAS such as acne, oily skin, potential acceleration of baldness etc. But mental effects are just as important if not more so.
The sad thing is if many come off (and stay off) they can go through deep depression. My advice would be to go to see a doctor. If your in the US I wouldn't say you have been taking AAS. Come off and say to the doctor you have been taking lots of legal prohormones such as mdrol etc.
Your test levels will drop fast after cycle and your body needs to start producing test naturally. This coupled with possible rebounds in estrogen levels can play havoc with your body. Fact is when you have low test levels you feel less of a man and mild depression is common. If you have pre existing issues coming off can result in deep depression and serious insecurity issues etc.
Like I said your best coming off and seeing a doctor and staying natural for abit. If you continue to struggle then doctor prescribed TRT may be an outcome. As long as you keep levels stable and as the doctor suggests that should help matters greatly. But TRT should be a last route if your only young. Let us know how you get on.
