ok so for someone who has a fast metabolism, please put up your calorie consumption on a daily basis.
Deca and tren both come from the 19nor family. both have different side effects, both can cause sexual dysfunction, hence the terms deca and tren dick. They both drop-down endogenous testosterone production, so running them with out testosterone is never a good idea.
next on the list is TREN IS NOT A GREAT COMPOUND. it is an incredibly potent compound but even then it can be like hunting rabbits with a bazooka. If you are in a relationship, you probably won't be after tren cos it causes some serious mental impact, every case is different, but i used 60mg of tren in my last contest prep per week and from the day injected it, i could feel the mood swings and change in demenour.
you would be better off using test and deca and actually throwing in a DHT like masteron enanthate for your bulk. set your testosterone at 3mg per kg (so max 250mg) for the 12-16 week cycle. add in 2mg per kg of deca (170mg per week) and about 1mg per kg of masteron. ( 100mg per week) run that for 4 weeks, then up your masteron to 200mg per week, and your deca to 250mg per week. and run the cycle out like that. you will grow pretty decently and should have minimal side effects with a cycle like that.
