Anyone have experiences with test undecanoate?

[Banana Joe]

I never had gyno issues when front loading the equivalent of let's say 7-800mg of test E in the past (there was also DBOL and tren which are not known to be less problematic in that regard).
I frontloaded almost all of my cycles and NEVER had this happen, and back then I surely overshoot the curve just to be sure I reach the peak as fast as possible.

 

[Spaceman Spiff]

I do have a a mild gyno episode

but I have been on it for over 2 years. Probably need to reduce my dose in general.


Never had gyno flare, it's on my right nipple only

but i dont think u get me.

u got 2000mg flutaction instantly, and you will be changing everyday 100mg in fluctactions.

test e 700mg fluctactions would be those 700mg in 3.5 to 4 days which is instant.
and then u would have to see how much you drop.

you drop from 700mg to 350mg in 3.5 to 4.5 days. so around same 100mg fluctactions every day the first half life. half of that the next half life.

so you were only rocking with half of what 2000mg would do over its 20 day half life in terms of hormone fluctactions. i dont seem to understand how u dont get how u got gyno?

test u is more stable if u didnt do this big front load

 

[Banana Joe]

but i dont think u get me.

No, I frankly don't understand what you are trying to say, obviously I am aware what a drug's half life is, and how blood serum levels correspond to that.
When I look at the two different curves that I just posted, I see virtually no fluctuations - other than going from being likely at the very low end of normal to the levels of being on 250mg, in a matter of let's say a week.
Am I aware there could/will be more aromatisation occurring during the jump from low end of normal to maybe 1500 levels? Yes - but I can't see a reasonable explanation for having my gyno flare up, as if I were on 1000mg of Test E or whatever amount of Test E might have caused that, if those curves were even remotely true for E2 while frontloading.

test u is more stable if u didnt do this big front load

Not according to BOTH curves I just posted.

okay, let me explain it very very simply idk if i can do better than this.

when testosterone is injected, some of it is aromatized into aromatese. so you're getting instant estrogen of 2000mg aka big hormone fluctaction from 0>2g

by that you're getting a huge ass estrogen spike which is better than injecting lets say 700mg test e vs 2g test u, because test u is longer and u have more time to offset it. and that is the same principle in running test u is more stable and less fluctactions therefore test u will always give u less gyno than other esters.


here is a better plot for you, so you can see how the frontload will affect estrogen levels until first half life is over (around week 6) and you can see its because the test u thats been injected at 250mg now have finally reached 1 half life and is beyond that which means we are reaching stability.



if u had done that from the start u wouldnt have big ass fluctaction. now mind u this is just a graph. your estrogen spike with this graph would have been way higher maybe because you're metabolising test u faster, or aromatize more than avg or some other factor.


you cant just go from 0 > 100% of the testosterone blood levels in 3.5 days u need, get the whole estrogen spike for it which will normally take 4-6 weeks to build up and then say test u is less stable

Test U is 100% more stable.... I don't know if you are interpreting it right

pour some tussin on it (low dose aromasin and ralox?)

Just got back bloodwork last night.
112mg test u 90mg deca pinned weekly. If I want to do a little blast, I'll supplement with NPP and test p

damn u have really good shbg, free test and e2 numbers for someone not natty. i would have guessed you were natural just from those numbers

I very well might be, as I am honestly struggling with what @dinfar1337 is trying to convey. And I don't think is primarily caused by me (or him for that matter) being stupid, but a language barrier.

i may be stupid but i speak english fluently, not profesionally tho.

haven't had issues getting understood yet i just mess up grammar sometimes.

 

[Spaceman Spiff]

I mean, I would rather reduce the dose by 10-20%. My goal is to minimize drugs and interventions.

Im using raloxo

Ok, and I am not meaning that in a provocative way, but I am really not getting what your point is therefore:

1. Can we agree, that if I am a hyper metaboliser I will be for U and E because it is the same enzyme at work?
2. Can we also agree that I reach stable blood serum levels of total test within a week if frontloading no matter the ester?
3. Can we furthermore agree that peak free test and E levels depend on the total test levels in blood, and NOT any ester that the test is delivered with?

If yes to all three, why does a frontload to 500mg a week of Test E with Tren Dbol on top does not make my boobs grow, while front loading to 250mg of Test U does?
I don't know your calculator but you can redo that for 2x500mg twice a week, and then 250mg e3.5d - there even is a overshoot I didn't not* get with 2g of Test U, because it is so slow.


*According to the calculators - which seemingly are unable to tell the whole story.
Which is the entire point I was trying to make with my initial post, as well as the latter ones.

what im trying to say looking at these plotters is your estrogen is rising for freaking atleast 20 days before its starting to fall. front loading + injecting with test u since its such a long ester will get u 4-6 weeks of peak estrogen

even if you only have 50pg estrogen on 250mg test u when its stabilised after those 100 ish days you would be double that so 100pg for 4-6 weeks!

the same peak estrogen u will only have a week of front loading test e because its out of your system so fast.

maybe you never could tolerate doing 500mg test 2 times a week, but u only did it for 1 week and not 4-6 weeks.

How is E2 level dependant on the ester attached to the test and and not total test in my blood? I don't know which plotter that is, but please run 500mg of E a week with 1g frontload through it and show that I will have less E2 with double the amount of total test, because it has been cleaved off E and not U.
I asked these 3 questions for a reason.

Your comparison just shows that I have less E2 peak if I don't front load. Everyone knows that already.
And that assertion can be made irregardless of the ester, if we are talking about C/E or longer.

I really don't don't understand what you are trying to convey.

You are just playing the guessing game. You have no data dude...

look here dipshit.

I am the biggest pushers of Test U here

I have more data and posted stuff here than you have. I have contributed more than anyone else here in terms of brewing and front loading from Test C

Thread 'Moving from Test C to Test U for TRT'

Nov 6, 2023

So I know some people have interest in Test U.

Test U itself has roughly a 21 day half life. It will help create less difference between the drug peak and trough on a weekly dose compared to test C
Some people may prefer this as theoretically may reduce the possible need for an AI(Yes this is controversial topic for TRT users).
This ester is not advised for people that are not on TRT as the PCT would be a pain in the ass.
You can do this ideally every 1-3 weeks. I personally use it weekly.

If I go on a trip and may be away for 2 weeks, I will hit myself with a double dose. No, I do not...

Thread '500-550 test U every 2 weeks.'

Jun 28, 2025

I didn't get a lipid because this came from my trt clinic. Not really too worried as I was just on trt.

It was not a fasting lab and it was 6 hours after a workout.

Main reason for this is to show test U 500-550 every 2 weeks
This is a trough lab test.

220 Test U a week. This is the Trough(6 days after injection)

871 total test
35.7 E2

EDIT: Wow its been a year since I been on his Test U
