I do the same. Androgel 1.65 is what I use. I use a tube a day and it has kept my test levels in the normal range. Gives me more energy and an edge so quite happy in those regards.

TRH is pretty much a normal thing and very common these days. I have been using the gels for many years and find that they keep my levels pretty regular. Not bad for an old man.

I am 41 and have been using the creams for about 12 months. I also use them in conjunction with the testapell. I have 14 placed in my hit. I have noticed a slight more sexual uplift, and a little bit more energy, but that is really about it. If anything, the most that its done is wake me up to the point where I want more. You suggest I should take Growth Factor in replacement of the creams and such?
Is growth factor something that a doctor will have to administer, and what type of results can I expect? Honestly, I am looking for strickly gym results. The sexual drives and so forth I dont much care about.

That's 1.5g per lb of lean mass per day ( I assume u meant that). The protein powder that bothers your bowls has casein and or caligen in it. You need to drink whey isolate protein. I recommend Isolyze by species nutrition (you can find it on this site's store).
If you don't take the above prescribed amount of protein, you'll never grow, and you'll waste the anabolic properties of your testosterone supplementation. Steroids increase protein metabolism, but if you don't eat enough protein, it won't work.
As far as HGH is concerned, unless you have a black market source, you can't "choose" to substitute it for the testosterone therapy. Unless your blood work reveals very low IGF-1, your doc won't prescribe it for you.
You should be eating 5-6 times a day, roughly every 2 1/2-3 hrs and evenly dividing your protein over those meals. Every ounce of chicken, turkey, beef, fish has 8g of protein in it. Every whole egg has 6g and every egg white has 3g. Have three meals with real food protein sources and 2-3 meals w shakes. There's no way around this. It's simple math and simple science.

You didn't say how old you are.
Only 10% of the testosterone in the creams make it into your system. So the creams have about 10 times the test in them than viable by design. That being said, your getting about 70-90mg of test per week under normal dosing protocol. That's usually enough to bring a 45+ year old man's testosterone level to mid-normal range. What most doctors don't test for and is paramount in providing proper dosing is Sex Hormone Binding Gobulin (SHGB). This is a "policing" protein that gathers up testosterone and estrogen, keeping it from binding with you androgen receptors. You should have your "free" testosterone tested as well as total. Only the free test is bio active. A normal or high total test with low free test indicated high SHGB. You want your free test to be high normal as a 45-over male for resistive weight training to be productive.
In addition, you should have you Insulin Growth Factor 1 (IGF-1) tested. If it's low, then your growth hormone release is low and muscle growth will be hindered. HGH (Human Growth Hormone) will fix that.
It's difficult to find a doctor well versed in male sex endocrinology. An Age Management clinic might be better suited to help you. As far as cycling on creams and implants…total waste of time. Ask your doctor for injectable testosterone for your HRT. It's much more effective.
