He almost definitely took PEDs. His body shape transformed from a gangly kid to a shredded WWE type with a V-back and and a wasp-thin waist, huge biceps. Sure he was working out, but average guys don't have the energy to work out for 3 hours/day, particularly when they play golf for 5-8 hours/day and bang waitresses for 2-3 more hours/day. In the past few years his physique has shrank and he's lost a lot of power. He's also suffered a lot of injuries, knees, back, etc----which is consistent with discontinued PED use.

By the way, Annika Sorenstram also seems to have taken PEDs. In one year on the LPGA Tour she improved her average drive from about 230 to 280. Nobody does that naturally. She also won about a dozen tourneys, grew a mustache, and got a divorce that same year. When she got off the roids, her game left her.

It's the same as baseball----PEDs increase strength, which increases swing speed, which increases power. If Sosa hits a ball further on roids, then so too would Tiger hit a golf ball further.
