only thing needed by anyone that enters a gym with bodybuilding and or powerlifting in mind is gh15 course of hormone intake 101-499,,when you done with those courses you will have your bachelor degree in hormone utilization and will look like a bodybuilder,,that is ALL YOU NEED,,
infact i may very well look into it when i retire depending on offers,,it will be strictly hormonal advice with adjustments to training and nutrition,,i do it better than milos and glass ,,i know about it more than milos and glass since both of them are obident by name recognition from goverment and living on usa grounds,,
so thiis is one aspect of gh15 fame i might make money out of past retirment \,,already offers from chicago to japan,,
if you come to gym for fun and for social activity personal trainers are good,,for bodybuilding you need hormone courses directly given with no bullshit so alot of trial and error is avoided and you can reach the pro card at age 23 rather than 33
