Size at puberty from Test & GH levels? And replacement therapy later in life?

(I haven’t made enough posts to be able to put this into the main Forum, so I’ll post it here, but if anyone wants to repost it there, feel free to) As best I can tell, most of our penis size happens during our teenage years during puberty. It just so happens that this is the time of our lives when we have the max combo of Testosterone and Growth Hormone. Look at this graph I found out out there:

We can see that Growth Hormone is at it’s max from the time we’re born and decreases from there. Testosterone shows up in our teenage years. These are the years we have the biggest combination of test and GH. This is obviously puberty when our penises get their biggest size increase, pretty much for life.

Am I correct so far?

And if so, what might happen if a man starts taking Testosterone (as part of TRT) combined with Growth Hormone (or the peptides that are the precursors for GH) ? Has there been any studies done that shows supplementation with Testosterone combined with GH may cause some kind of penile growth if this is done later in life?

I don’t know, but i suppose reason for size increase is rather stress with following recovery or mass gain. For example, during hanging person stretches connective tissue to make it bigger and with good erection it fills completely. And during puberty size increases because natural growth to full size coded in genes. So maybe some supplementary effect? Because there is no reason for growth in single hormone therapy. I heard people with undeveloped penis can increase size from taking testosterone, or something like that. But again, those are undeveloped with bigger sizes in their genes which they didn’t naturally got.

I am also curious on this topic. I feel like i have all my life been experiencing symptoms of low T. Mild gyno, barely any hair on arms, no hair on chest and non existent beard. Very late puberty since i got my hair in armpits at like 16-17 (i am 20 now).

I am not small by any means at 7” BPEL and 5.2” MSEG but i feel like i could be bigger since my dad has a HUGE unit at 9 inches. Before questions like ”How do you know about your dads dick blablabla” i’ve seen it flaccid multiple times and once he told me that he has a 9 incher.

I know the logical explanation is genetics. But i just feel like i maybe lack of testosterone or maybe due to some other hormone imbalance i did not become as big as i could. But i am not really sure how hormones work either, can you lack hormones responsible for manly features and penisgrowth etc. during vital years (like from age 10-16) and then have normal levels at 18 and therefore ”mess up” your growth?

Or should normal levels kickstart the growing and fill out your genetic size?

Either way i will soon test my hormone profile and see. If everything is well i will try to stop this way of thinking and just be content with what i have and enjoy life and do PE. Another thing that kind of ”supports” this theory of hormones and size is that i barely ever see anyone with gyno or other low t features that’s really big.

I suspect the lack of studies on this issue stem from a lack of illness.

In these developmental years hormone supplementation has the potential to be disastrous if not needed. Excessive testosterone is a medical condition with side effects that include baldness and other endocrine complications.

I doubt studies in this area will be done unless the risks are weighed against certain poor results being caused by an illness affecting testosterone or growth hormone production.

Look at pro bodybuilders on stage, you decide.

I know there’s a tendency for people to attribute one’s natural size to “genetics” but “genetics” are really just “instructions” telling the body what to do like “pump out out more Testosterone and GH at this level for this period of time”. Which makes me wonder if the test/GH combo has a lot to do with size.

As for bodybuilders, it’s common for them to dehydrate themselves for competitions so that the muscle striations are more visible. Might this have an effect on penis size? Combined with tight speedo’s? But bodybuilders might be a good example for this question. Does anyone know if bodybuilders taking anabolics (when they’re not dehydrating themselves for competition events) make any gains in penis size just from the use of Test and GH?

The only issue with this argument is that every body reacts differently to the same amount of a chemical. Different reactions to various doses of testosterone and HGH are plentiful.

Genetics does decide how much of those we naturally kick out. But simply kicking out more is an overly simplified answer. Too much testosterone can be harmful and malfunctioning pituitary glands have caused various rare illnesses with causing testosterone and HGH spikes past the human body’s natural design. Notable cases are gigantism but also feature sped up development (rare cases where 2 year olds are the size of a 13 year old but stop growing by age 9) and odd growth patterns.

Genetics are more complex than simple static levels of a chemical. The time in life they are released, frequency and reaction are just as pivotal if not more so.

Just my .02

Mm, well i dont think your view of genetics is really right. Genetics is more like a blueprint, hormones and nutrition are the building blocks. A man suffering from low t all his life from pakistan had his penis grow like two inches from testosterone injections since the body was now able to fullfill his build in blueprint in his DNA, even though he was like 30-something years old.
