We establish integral tests and laws of the iterated logarithm at $0$ and at $+\infty$, for the upper envelope of positive self-similar Markov processes. Our arguments are based on the Lamperti representation, time reversal arguments and on the study of the upper envelope of their future infimum due to Pardo These results extend integral test and laws of the iterated logarithm for Bessel processes due to Dvoretsky and Erdös and stable Lévy processes conditioned to stay positive with no positive jumps due to Bertoin.
