If you have gone through pubery then your hormone surges are done...
Try 20 rep squats to boost your GH levels
In Brians case, 11 reps...you know those mensa people and counting
I believe there is a surge in hormones that come as a person nears 30...
Sauna and cold plunge are excellent for recovery, inflammation (hear that Brian), and HGH elevation (limited studies and require the 160 - 180 deg ones).
