An interesting video on trenbolone, what I like is the fact this guy has done the research and there are some interesting points, he explains all the in the video.
of note, his research again supports the idea of nutrient partitioning, trenbolone apparently causes massive insulin sensitivity in muscle, ( glut4 ) . This is as opposed to increased insulin sensitivity in adipose tissue, ( glut4 ), which causes fat gain.
So the point seems to be, where is the insulin sensitivity and in particular where is the glut4? That plays a big part in where your "calories" go. The same is also true for LPL. Skeletal muscle LPL protects against fat gain, while adipose LPL increases fat gain. ( link )
For the record, I dont agree with everything this guy says, im just sharing an interesting video.
