I have low free testosteron, probably due my stupid cycle 3 years ago. I still have it on normal range, but it is on the below line which seems is not enough for my normal life.

I am wondering how is about beeing all life on testosterone. Not high doses but just a little bit, to put values to the top line of the normal range. This would mean to dobule my free T (now is 8 pg/ml while normal is 4.25-30.4).

My main concern is that if I use this little doses let's say for 10 years constantely. Can this decrease even this little value of natural production that is left? Or would be those little doses to little to make any damage since it would be probably still the same as before natural production and I can stop it any time?

Tnx for any thoughts!
