No. Only that Lee took cortisone for his back injury. Polly endorses the weight training story of how Bruce injured his back.
Even though Polly cites and quotes from Tom Bleecker's book, he doesn't seem to have a high opinion of some of Bleecker's claims.
In his harsh biography, Unsettled Matters, Tom Bleecker claimed that Bruce Lee abused steroids for years (pp. 85–87). Since his book contains no footnotes or endnotes, I asked him during our interview if he would provide me with evidence for his assertion. He refused. Bleecker’s book fanned long-held suspicions of steroid abuse. During my research for this book, I made a point of asking almost everyone who knew Bruce about it. About half strenuously denied it (Linda said, “Oh God, no. Never.”), and about half started to whisper or asked me to turn off my tape recorder. The latter didn’t have any evidence, but they still believed it and didn’t want to be on the record tarnishing his image.

59. In Bleecker’s scathing biography, he draws broad, unsubstantiated conclusions from Lee’s cryptorchidism—claiming that one undescended testicle caused Bruce to frequently suffer from impotence, an inability to develop a mature musculature without the aid of anabolic steroids, and “psychosocial immaturity” (pp. 19–20, 38). These claims are absurd. The only two physical risks associated with cryptorchidism are infertility and testicular cancer. It does not cause impotence or stunt muscular development, and there are no proven psychological side effects. Lee fathered two children, had an active sex life, and had the same wiry musculature in his teenage years as his two brothers.
