If you are 19 and you used
M1T then your test level after discontinuation would be as low as that of a female. Don't kid yourself, PCT is essential!!!!
As to the whole test level issue in young men etc. Yes, some young men have less testosterone in their blood than others, but if there is a balanced HPTA then NO AMOUNT OF
TRIBULUS WILL HELP. Stimulation of the Leydig cells is done if you have too little
testosterone as far as your natural balance is concerned. If you are in balance, but you have a lower level of test (but still balanced in respect to estrogens etc) then stimulating the Leydig cells will help nothing since (yes in short term it might raise the level a bit) the feedback loop will negate the effects. If you however come off a cycle and your feedback mechanism is busy getting rid of the estrogens and pumping the testosterone, ANY help may it be from Tamoxifen/Clomephen/
Tribulus will stimulate the process where Clomid is the most potent and
Tribulus most probably the least potent (I stand under correction if someone has heard of a new study about
Tribulus)
Another thing. Most
endurance athletes have a lower testosterone level than normal men and many weight lifters (natural/no roids etc.) have slightly elevated levels. This is how the body compensates for the effects of training so if you are 19 and lift weights you should have an even higher test level than you would have without lifting. Just don't overtrain! This obviously will kill your test level!
