What blood assay to pull when having low libido

Hey guys,

I have been on TRT for 7 months now and for about the past 1 month or so, I have been experiencing low libido and lack of random erections I once had. I do usually get morning erections but not as much as I normally did.
I am currently on 160mg split 2x/wk. I got off hcg in December due to still having anxiety despite being on adex and e2 normal. I am now only on T at the moment.
I am going for bloods this Thursday and was wondering what assays should be pulled to check for these issues, aside the obvious e2? I never had DHEA or DHEA-S tested and assuming this would be one of them. Prolactin will be checked. Anything else specifically?

Much regards.
 
Здравствуйте! Меня зовут Сергей, я из России. У меня проблема с тестостероном. Где можно задать вопрос по результатам анализов? Поблагодарить.

Interpret please??
 
Translated from above: "Hello! My name is Sergey, I'm from Russia. I have a problem with testosterone. Where can I ask a question on the results of analyzes? Give thanks."
 
Is there a way to add this panel to the "TRT MALE Hormone/Wellness Follow Up Panel" without paying for duplicate parts like Test and e2?

DHT and prolactin.
 
I created this panel:
ED Blood Test Panel
Thanks Nelson I saw that in your original post above. What I want is to combine that panel with the other health marker tests from the hormone/wellness follow up panel but not have to pay for double T and double e2. I think silver surfer answered my question... I just need to add prolactin and dht to the wellness panel in order to essentially combine the two panels.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
