So I take it that while your on TRT, you do not experience testicular shrinkage or testicular achiness?

No achiness but some minimal shrinkage (maybe ~10-15%). I'd like to not let my natural production die down completely, but hCG is unbearably estrogenic for me. Once I've dialed in Test + Primo I'm going to try Kisspeptin-10. I've seen some anecdotes of guys doing really well on it even with subQ injections (as opposed to IV as in the studies).

 

[Jerajera]

What do you think about running test prop alone ( or perhaps test prop/primo, in your case) for several weeks, then hCG on its own for a few weeks?
Would T levels be too low on hCG alone, following suppression from the test prop?

For me at least that would lead to some severe ups and downs. The dose of hCG I would have to run to retain even middle of the range Free T levels would probably give me high E2 symptoms that would make my life miserable, not including the withdrawal symptoms from the Test.

I think in general if you can tolerate hCG, running a small dose constantly is probably a better bet. It's hard to know for sure but I don't think there is evidence of any desensitization unless perhaps at ridiculous dosages. Something like 350-700iu/week is most likely safe to run "forever".

I do get very significant benefits from hCG in terms of libido and cognition, mood as well. So if the Primo is a strong enough AI to control the extra aromatization from the hCG, I'll be more than happy to run it. Even at 50iu/day it made a massive positive difference for me until E2 ruined the party.

 

[Jerajera]

Note that Primo reduces libido in some people. This may be due to the anti-estrogen affects, so hopefully it will still leave you in a good spot.

That's my theory as well, oftentimes in those anecdotes there is some implication that E2 levels got too low. For ex the guy will say he had great libido for a while and then it completely crashed, or something along those lines.

I've started keeping track of different symptoms daily in a spreadsheet - libido, erection quality, morning wood, water retention, mood, cognition, etc... - so hopefully I'll be able to follow what's happening and/or trace it back after the fact once I realize I've been looking at women for a few weeks the way I'd look at a plank of wood.

Hcg mono is tricky. Was on it for a couple years. Lots of variables to consider, which make it not ideal, imo, to use as a monotherapy, no matter how long the person plans on being on it

First thing is everyone is going to respond very differently to the same dose of HCG, as far as test production goes. All depends on how well it personal leydig cells in ur testicles respond to the LH signal from the HCG.

Then u have to factor in the quality of the hcg

Then u have to factor in how many days from the reconstitution date ur using it. HCG degrades as time goes on, post reconstitution. So ur not going to get the same response from it after say 20 days, as u did when u first reconstituted it. And then even less of an effect after 30-40 days post reconstitution

Then for some guys the amount of estrogen they get from a certain dose, is just too high, compared to the testosterone boost they’re getting from it. I had a ton of issues with itchy/ sensitive nipples, while on hcg mono, and started to form gyno. I would scratch my nipples until the point they would bleed. I’ve never had this issue on testosterone, even when running much higher test levels than I was getting on hcg mono.

Hcg mono is just not an ideal option for low test, imo. But just my opinion. Oh, and storage of hcg is a little bit of a pain, like if ur traveling or going away for a couple days or what not. Just a bit more inconvenient to have to worry about keeping it refrigerated, compared to a bottle of test

Also, only half of the testicles respond to hCG, the other half equals none response according to Dr. Saya.

This is why men typically achieve higher testosterone on TRT when compared to hCG.

Oh interesting, didn’t know that. I was a pretty good responder, to pregnyl HCG, at the time. 2000iu’s/ week consistently had my total test level around 1200, and 1000iu’s/ week had my total test level around 600. It was actually pretty crazy how consistent my test levels would be on the HCGA mono, at the time.

Now I feel like pregnyl HCG is like injecting water. For some reason I just don’t respond the same to it. Does nothing to prevent testicular atrophy, doesn’t seem to boost my test levels at all, and downstream hormones like progesterone and DHEA are unaffected by taking it. Compare to when I was on HCG mono, and my prog and dhea levels were always higher than not being on HCG

At least take a moment to read about Sertoli cells and Leydig cells so your posts on the subject have some redeeming value. You'll find that Sertoli cells respond to FSH, while Leydig cells respond to LH and hCG, which is presumably what Dr. Saya was alluding to. TRT-induced testicular atrophy is caused by a lack of both LH and FSH. With hCG you are replacing the LH, but not the FSH. Therefore, hCG alone may not completely reverse the atrophy due to the lack of Sertoli cell stimulation. However, Sertoli cells do not contribute to testosterone production.

The reason why men can "achieve higher testosterone on TRT when compared to hCG" is that in TRT you can increase the dose arbitrarily to increase free and total testosterone. With hCG you are limited by what the Leydig cells can produce, and worse, excessive amounts of hCG actually reduce testosterone production compared to lower amounts.

So hcg alone is not the answer for fertility. I wonder if I can get FSH via compouding pharmacy

It is for plenty of guys anecdotally, so I wouldn't make that assumption. I think the ones who fail to regain fertility on hCG (assuming pharma, dosed high enough, etc...) are in the minority.

I think there are studies showing fertility preservation on TRT with hCG alone. There you go: Indications for the use of human chorionic gonadotropic hormone for the management of infertility in hypogonadal men

"It was later shown that not only is intratesticular testosterone increased with co-administration hCG but spermatogenesis is preserved as well at one year follow up".

To be precise, that study is about preservation not recovery of fertility, but anecdotally it extends to recovery I think at a very high success rate.

Depends. I’ve had two kids while on TRT and HCG, and I’m sure thousands of other men have as well, and some not even using HCG. But then there’s obv some guys that need more, which is where things like FSH, HMG and Clomid, come into play

Testicular size comes primarily from the sertoli cells, right, Cat?

I don't know for sure, but this work says there are about four times as many Sertoli cells as Leydig cells. If the cellular volumes are similar then it would imply that Sertoli cells are the bigger contributor to total volume.

Seminiferous tubules/germ cells.


* Since 80% of testicular volume consists of germinal epithelium and seminiferous tubules, a reduction in these cells is usually manifested by testicular atrophy and this reflects the loss of both spermatogenesis and Leydig cell function

*Spermatogenesis is largely dependent on the action of FSH on Sertoli cells coupled with high intra-testicular testosterone concentrations. Within the seminiferous tubules, only Sertoli cells possess receptors for both FSH and testosterone. Numerous signaling pathways are activated when FSH binds to FSH receptors on these cells. It acts synergistically with testosterone to increase fertility and the efficiency of spermatogenesis

Menopur Effects On Ejaculate

Quick questionsl guys. Has anyone taken Menopur and seen a difference in ejaculate volume? I've been on TRT a few years along with HCG and my ejaculate volume is definitely less than it was before. Me and my GF are trying to conceive so I'm including Menopur in my stack but I wanted to know if...

Man crush reported. Thanks for taking the time to type that out. You are misinfo's worst nightmare. Do you have an official internet fan club? How do I join?

What's your test prop dose and injection frequency?

Try Bimix. Zero side-effects, much safer than Trimix and rock-hard erections within 5 mins of injecting.
