on a side note - the cattle in the study group that received Tren had more lean weight gain and much better feed efficiency even though their T4 levels were supressed.
imagine how much more that would be if they were given Tren and a bit of T4 as well.
had plenty of clients wonder why I'm recommending them running T4 during a "bulk" with low dose Tren (well because the Tren is going to suppress your T4 levels , and having some additional T4 will only help your feed efficiency even more)
