The studies were conducted by military doctors in a MASH unit, but it was more than just lining up field personnel to give them so-called malaria vaccine or STD protection (penis-sealin' as the privates continued testing their privates on the unsuspectin' infectin' whores)
The Rolling Stones were visiting, and one of the surgeons concocted this scheme just to get a private performance of Mick and the band in the MASH unit "to lift the morale" of the wounded.
The Stones were knocked unconscious and the testosterone shots were administered, with their consent and the patients being witnesses. The Stones were going to go public with these unofficial tests. Unfortunately Altamonte happened, and the rest is history. When they tried revealing the test results, it was drowned out by the media wildfire from Hells Angels at Altamonte.
You can make this shit up.
