Hi guys , I have always had in mind trying tren since it has the best reviews out of all AAS for mass and fat burning, I have seen mixed opinions about tren being renal toxic and also is the roid that causes the most back pumps due to it's negative effect on the kidneys, I know a few guys that use AAS and they say that their urine is darker when they run tren more than any steroid but still gains are awesome, I have two cycles under belt, both test and winstrol and I get gains but I want to get more serious about bodybuilding and I'm looking to compete next year so what would be the ideal cycle of test and tren? I'm28 years old, my height is 6'0 and weight 180 pounds, work out 5 days a week, mostly compound movements , thank you for your advice.
