Exactly...at a WADA symposium about a year ago, they said EPO microdosing is
undetectable & prevents a challenge in curtailing it's use. Now they've added
growth hormone to the module of the ABP - so that along with anabolic steroids will be difficult to use & not test positive (I can't imagine anyone using anabolic steroids with their long glow times. Lol).
World Anti-Doping Agency to launch a new module to detect human growth hormone.

However, synthetic testosterone is undetectable without utilizing the
CIR test, which is very expensive generally used only when an athlete breeches the 4-1 T/E ratio. I believe the normal ratio for a male is 1-1 with 2-1 being outliers. Decades ago the T/E ratio was 6-1 for suspicion of testosterone use. WADA lowered to 4-1 concluded this number would be sufficient evidence of exogenous testosterone use.
Good info from Matt Mosman, MS, on the EPO/testosterone cocktail use by dopers in endurance sports:
