Injected T is testosterone ester dissolved in oil. You inject that and it takes time to be absorbed. As the T esters become free molecules, a few different process strip the ester group off of the T ester, which yields bio-identical testosterone. All medical testosterone is synthetic because it is man made.
There are many anabolic steroids that are not testosterone.
200mg every two weeks is horrible. You need to self inject and inject 50mg twice a week.
You probably need a different doctor. Yes, there is a sticky for that.
Read the protocol for injections sticky.
hCG should not be used in high doses to increase T, that will create high E2 levels. hCG will work if you are younger and have health testes. If your low T is because of the testes, hCG will not get the job done.
Post your lab number and ranges.
Some drugs can lower T.
In many cases, the issues can be more than replacing testosterone. Read some of the threads here.
