Androgens potentiate the effects of rHuEPO:
https://www.ncbi.nlm.nih.gov/pubmed/1986567The Russian's were using androgens in combination with rHuEPO to potentiate the effects of an ESA. ? One example given on page 141 of the McLaren report:
"11.7.3 Coach Vladimir Mokhnev"
"Coach Mokhnev is an ARAF running coach. The allegations against coach Mokhnev
stem from whistleblower Stepanova’s statements, which are supported by the secretly
recorded conversations.59 She is the IC’s main witness related to Mokhnev’s Code
violations. Through Stepanova’s statements and secret recordings, the IC investigation
uncovered evidence implicating coach Mokhnev in violations of the Code, specifically
sections 2.8 and 2.9. The following material discusses his role in providing athletics
athletes prohibited substances.
Mokhnev became Stepanova’s coach in 2006 and by the summer of 2007, Mokhnev
began providing her with erythropoietin (EPO) injections along with dosages of oral
Turinabolan. The IC notes that oral Turinabolan is banned in Russia under the Russian
Federal Criminal Code s. 234 and contains DHCMT, a prohibited substance. Mokhnev
instructed Stepanova how to inject EPO, initially in the arm and then into her veins. As
a result of her EPO and other PED usage, Stepanova’s 800 meter times improved to
2:03.47 from her early baseline of 2.13 and early personal best of 2.08:47. Stepanova was
informed by Mokhnev that the drugs would be detectable in her sample for 40 days
after her use of Turinabolan and nine days after the use of EPO.
Mokhnev instructed Stepanova to keep a journal of the prohibited and non-prohibited
substances she was taking.60 Stepanova complied and tracked and documented her PED
usage and then calculated the exact time she needed to stop taking PEDs in order to test
clean at competition events. "
