Firstly, there is no convincing evidence that any dose of L-arginine is of any benefit for the stabilization or reversal of PD associated penile curvature. Saying that, it is a very safe agent so high doses as outlined by the other clinician is likely to cause you no significant side effects. Occasionally, patients complain of facial flushing with high dose L-arginine.
