My levels have been good after I started to move more, eat more decent, drink 4-5L clean water every day. Protein shakes and coffe not counted.
My levels rised after a period of inactivity, and now I am around 15-16g/dl
And I try to keep y T levels around 700- 1000ng/dl
One pump made me down to 300ng/dl, now I'm doing 2 - 3 pumps.
Testogel or androgel is same, just a different brand, and I really do not like it in hot climate like Thailand.
Testovan is much better gel, but I prefer testoviron. Rotexmedica was also easy available in Thailand, not sure they changed name yet.
Just stay away from underground labs, which is easily available everywhere in Thailand.
