Both Tren and Winstrol will wreck your lipids. People today use tren like test which is playing Russian roulette with their health. There was a time when tren was used sparingly. Now guys are using it on every other cycle. A few years back I was on a cycle of tren and I got sick from something I ate. I paid a visit to my Dr and after testing he thought I was on the verge of kidney failure. I pleaded with him that I wasn't. He accepted my pledge that I would go back to retest in a couple months and I assured him my kidneys would be back in range. I did go back 3 months later after dropping the tren and my kidneys were normal again. Doc knew something was up. He lectured me. I still ran tren a couple more times after that but at much lower doses.
Do you recall what dosage you were running when he ran the bloods?
