If you experienced gains like that on your first cycle you defo dont need to be running Tren on your 2nd cycle.
Tren is a very powefull compound and does have some serious sides, these sides are not for someone who as just started using AAS, they are for the advanced user, at your stage you dont need it when your having gains like that,
I would just add another compound to your stack but not Tren or even stay as you are and concentrate on your diet, no need to start running when you only started crawling.
