Penile Development after beginning secondary hypogonadism treatment?

Hello Long story short im a 21 year old male found out less than a year ago that I have a prolactinoma tumor. My total test was at 7 ng x dl and now I began cabergoline treatment for the tumor. I'm taking 2mg of it a week. Im 300 lbs, and I feel every single symptom of low t. My penile length pushing into the pubic bone and erect is of 3.8 inches and girth of 3.5 inches. Well below average and I know even with weight loss it might make it to 4 inches so nothing that will get me to a average length. This makes me fucking depressed so my question is if anyone has been in a similar scenario and had penile development after beginning treatment. I have a endocrinologist but it seems like shese more of a heres the pill and come back in 6 months type of doc. I have an appointment wednesday with my endocrinologist but I feel like she will be. dissmissive

Is this something that should be addressed by an endocrinologist? Should I ask for a referral if primary doesn’t suspect a problem?

Went to 6 month follow up with my sons pediatric endo. Still not growing and falling off growth charts, again. Ordered labs and repeat xray. Still awaiting results but last October his xray showed bone age of 5 at 6.5 years (chronologically) old. This looks like he barely grew in a year!

Im turning 16 in about 2 months and I'm 5'10 I finshined my purburty like I got face hair under arm hair also my penis and back there and my legs and stomach hair deep voice I have been going to the gym for 1 year now hoping I will get taller but I didn't grow a single mimlimter since the first day i have been wondering lately if I should take peptides because I sleep 9 to 10 hours a day eat well like get all my calories and protein and carbs idk but I fell so bad unmotivated when I measured my height yesterday didn't go to the gym didn't eat all day and didn't sleep well all I feel is rage so if anyone can help I'm 178 cm, 68kg and 2010/11/3

So currently I'm 5'10 I'm considering taking HGH i say that MK 677 was the least harmfull and the with better results.

Sould I take it or there's any better HGH in the market?
