Mast and proviron both increase free test by lowering shbg.
I would experiment by getting bloods mid cycle on mast.. Then adding provi and seeing if your shbg lowers further, I'd guess that it wouldn't though.
Hey guys,
My name is Chris, I'm 22 years old and started lifting almost 2 years ago.
I'm 6'2 weighing in at 92kg(202lbs) around 10% bf.
My goal is to get to around 105kgs with a mixture of strength and hypertrophy training.
