That is at doses higher than most users, but not hugely so... the effect was seen with doses as low 5mg/kg.
The only similar alternative is Telmisartan, an Angiotensin receptor type-2 antagonist.. Telmisartan is also a PPAR-gamma agonist.
Supposedly, Telmisartan causes similar results with *far* less toxicity... and of course WADA banned it last year.
