Margitta Gummel (née Helmbold, 29 June 1941 – 26 January 2021) was a German Olympic gold medal-winning shot putter.

[10] A 1997 paper from the journal Clinical Chemistry reproduces charts from a 1973 DVfl scientific report that plot her Turinabol doses and competition distances for 1968, 1969 and 1972.

[11] Gummel was administered Turinabol at a dosage of merely 10 mg daily leading up to the 1968 Olympics where her throws improved from 17 m to 19 m in the three-month cycle.

In the years following higher dosages of Turinabol were used with performance increasing in a dose dependent manner, and her throws improved to well over the 20m mark.

Simply put, the GDR researchers commented that anabolic steroid use in females produced significant increases in athletic performance that were far superior to years of training naturally.
