Applauded 100th circuit with performance-enhancing drug (7)
I believe the answer is:
clapped
'applauded' is the definition.
('clap' can be a synonym of 'applaud')
'100th circuit with performance-enhancing drug' is the wordplay.
I cannot quite see how this works, but
'circuit' could be 'lap' (synonyms) and 'lap' is located in the answer.
'drug' could be 'c' (C is an example) and 'c' is located in the answer.
The remaining letters 'ped' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for clapped that I've seen before include "Applauded" , "Acclaimed" .)
