Strongly suggest you find a good urologist or a clinic. Do not get gear online and expect safe and accurately dosed stuff.
There are labs from Ukraine Bulgaria ECT that are legit, but if you get caught, depending on your state or country, you're totally royally fucked.
Get a doctor, get some labs and go from there. If you're in the USA and want some suggestions on reputable doctor resources pm me. But again I stress that you should NOT go outside the law and I don't recommend illegal underground pharma.
You can get TRT from an outfit like MaleExcel.com. They will have you consult with a doctor, then set you up with a prescription if you pass the criteria.
Most people can produce a low T level for the purposes of getting a TRT prescription. T levels vary during the day, and vary due to circumstances. T levels are highest in the morning. Also, a winner who has just won a fight has a very high level of T. The guy he just beat has a low level of T. On a more mundane level, a guy who eats well and lifts heavy has higher T. A guy who is run down and feels like crap has low T.
So, as is obvious, when you have to do the mail-in test for your T levels, you want to do it in late afternoon, put yourself in a state of being run down, and work yourself into a defeatist state of mind. Stay up drinking the night before, and dwell on every mistake you have made in life in the hours before the test.
This will drop your T levels as far as they can go, and will enable the Dr to approve your prescription
Obviously once the prescription is approved, you should go back to eating right, getting plenty of rest, and thinking like a winner.
