I find the half life is 10-100 minutes. Say I applied one tube of 5g... how long until my levels are back to normal? I ask because my friend is in trt and rubbed one 5g on him 2 days ago while on trt and he needs to get bloods drawn and he does not want it higher than it should be. Say he put it on Monday and got bloods Friday. Would he be back to just his baseline trt?
