We have a hard time working with saliva test results here, simply little experience.
With one teste, ideally, the HPTA will increase LH/FSH to get higher T production from the remaining teste. Your results seem to indicate that this is happening. However, if the lab work is while on TRT, LH/FSH should approach zero.
Saliva testosterone is a measure of free testosterone. Your result appears to be decent.
Your high E1 and E2 suggest that your liver is not clearing estrogens or E2 production is very high or massive amounts of aromatization from high dose T injections -if labs are post TRT.
Lab work that measures "liver markers" can help with the possible liver issue.
High LH might be prompting extreme T-->E2 in your teste - a possibility.
A TRT protocol in-line with what is recommended here may resolve the E2 issue.
When you inject every three weeks, the lab results are more a function of when you do the labs than anything else. The results suck and the lab results are mostly meaningless. Lab results should be highlighting problems, but most of all should be guiding dose refinements... that is impossible.
You need new lab work, blood work, but first switch to suggested protocols.
Many here will suspect that there are other problems. Test fT3, fT4, TSH, morning cortisol, ferritin and a lab panel similar to: http://www.lef.org/Vitamins-Supplements/ItemLC322582/Male-Panel-Blood-Test.html
which also incorporates: http://www.lef.org/Vitamins-Supplements/ItemLC381822/Chemistry-Panel-Complete-Blood-Count-CBC-Blood-Test.html
You can pay for the above lab work out-of-pocket for a lot less than what a doc would charge if not covered by insurance. We can do a better job of working with your labs than almost all doctors.
Aches and pains: Lyme disease is a technical possibility. http://en.wikipedia.org/wiki/Lyme_disease
Have you traveled to any tropical countries prior to all of this starting?
