Yea and no. Depending on the results of more thorough blood tests there are protocols to follow for a restart, the gel isn't one of them.
Maybe, a restart protocol is based on what's actually wrong, which is why more thorough bloodwork before starting on testosterone is important
Imo get some test run that 500mg for.life its just advice man
The endocrinologist is going to make you come off the gel for a couple months anyhow to try and get accurate bloodwork so there's not much point in using it for a month
