Taking nothing away from Andy's TRULY phenomenal lift, you still wonder what old-time great deadlifters like Hermann Goerner and Bob Peoples could have done with all of the androgenic aids and support gear/equipment aids available to Andy Bolton?
Way back in the 1920's, Goerner deadlifted 850 lbs. in front of creditable witnesses (weighing about 250 lbs.), and Peoples did an official 725 lbs. at about a 185 lb. bwt. in the late '40's/early 50's.
It is generally acknowledged that androgenic drugs increase your lifts by approximately 1/3 (approx. 33%), and then what about the additional aid of the support gear (deadlift suit), special bar, etc. (?) another 50-100 lbs.?!
0f course, guys like Goerner and Peoples were totally drug-free and did their deadlifts with only the aid of a 4" wide single-ply lifting belt at the most.
In Goerner's case, if we added just the 33% to his 850 lb. lift (the added androgens) that would be an increase to an 1130 lb deadlift.; not even considering the aid of any support gear, special bars, etc.
In the case of Bob Peoples, adding the 33% androgenic aid to his 725 lb. lift would increase it to 964 lbs.; and add at LEAST another 50 lbs. with the aid of the deadlift suit and you are up to 1014 lbs.(!!) (and Peoples weighed approx. ONLY 185 lbs.)
Food for thought!
