I am no doctor but I seem to already know more than some doctors do - it is amazing how many of them will script things for you even when they don't know anything about it, lol.... I would read the books I noted by Dr's Shippen and Crisler. Dr Shippen is widely recognized as a TRT guru and Dr. Crisler learned from him. Different applications have beneficial effects on the body.
For example, I am using 200 mg a week (2 shots a week) of Testosterone Cypionate, 500 units of HCG to maintain natural production, and some Arimidex to control conversion to estrogen + 50mg a day of generic Androgel for it's high conversion to DHT (which has a powerful libido effect). You just have to watch that DHT and PSA (prostate indicator) because if you are genetically prone to balding or to have an enlarged prostate it can make you lose your hair or enlarge your prostate.
The thing I have found is that every person is different. You almost can't use test results and dosages of other people to gauge the effect on you. And the "sweet spot" (the point of the best results) is different for each person also. The Dr's go over these things in the books. Having a knowledgeable doctor means they will not be afraid to prescribe what you need. My doses are a bit on the high side and we may reduce them in time if I can keep the good results. I am not a professional body builder. But I do work out about 4 times a week with weights and the results are amazing. If you have been doing TRT for 4-5 weeks, you should be seeing results soon. Common issues where people don't see results can be from Testosterone being converted to Estrogen. Or if your natural production drops off and you end up back where you started - basically just replacing your natural production with exogenous T. You just won't believe how great life can be when you get the proper balance dialed in. I have experienced both (I am 37) and you just are going to be so happy when you find your "sweet spot." Just be sure your doctor is one who specializes in HRT / TRT is a big step in the right direction. I changed docs immediately when I realized mine didn't even know to include Estradiol in my blood labs. Proceed with optimism but caution too. I have no fear - but I am cautious.
What is your protocol (meds and dosage) and do you have any labs since you started?
