Interesting that test enan is recommended to use 2x per week while cyp is weekly yet their half lives are nearly the same.
 
Some of those don't look right to me. TNE was closer to 7 to 8 hours I thought, thus 2x pin a day. Not 2 to 3 hours. 2 to 3 hours might be a good time to pin pre workout though.

And E and cyp, pretty sure those are longer than 5 to 6 days. I wanna say closer to 10-12 days on both of those.

All in all though, SOLID post brotha.
