Read previewCleveland Cavaliers big man Tristan Thompson has been suspended without pay from the NBA for 25 games. The two drugs found in Thompson's system — ibutamoren and LGD-4033 — can be used for performance enhancement purposes and may have dangerous side effects. Ken Blaze-USA TODAY SportsAccording to the NIH, ibutamoren is a growth hormone secretagogue, or a substance that promotes the production of growth hormones. Heightened growth hormone in one's system can increase muscle mass, limit body fat, and improve exercise tolerance, per Mayo Clinic. And in 2019, John Collins — then with the Atlanta Hawks — spent 25 games on the sidelines after the league found pralmorelin, another growth hormone secretagogue, in his system.
