Test undecanoate - high estrogen?

Hey guys,
I was on 100mg a week of test E (split into 2x weekly) and recently made the switch to Test U (pharma as it's prescribed).

On test E, my estrogen was always fine even a little low sometimes.

I'm using 1mL (250mg) test u every fortnight, for the past 6 weeks and getting sore nipples and big lumps under. I didn't Front load a huge dose or anything.

Anyone else had this when switching esters?

And yes I intend to get bloods as soon as I can, I have been traveling so haven't been able to. But I haven't had high E for a very long time on my dose of test so I'm not sure if changing esters can change that.

Did you stopped injecting test E for how long before starting test U?
 
If you are using 250mg every four nights, that might be the problem. Oh, wait. Fortnight? What the hell is a fortnight? Lol

But seriously, get labs soon. E2 sensitive has about a 2 week turnaround. When you say prescription, do you mean Nebido? It has a half life of around 3 weeks. You are pinning every two weeks. That’s likely a lot higher dose than you were taking on Test E.
 
Stopped pinning test E about a week before the switch.

Yes using Nebido.

Dose is pretty much the same - 250mg test U every 2 weeks opposed to 100mg per week test E.

So you had overlapping of different ester.

Try pinning once a week and see if it changes anything
 
Test E is still not quite out (even though it's not a big amount) and is interfering with your test U. Can't tell anything without bloodwork.
 
Also forgot to say that the test U is not anywhere near at stable level yet. So you need to do a blood test and see where your levels are at. Use steroidplotter or steroidplanner to see what I mean. It takes a very long time for test U in castor oil to reach stable levels without front loading.
 
I switched to test u from c years ago and it was seamless. I also had a fairly elaborate plan that I stuck to, which made the transition very easy. Try shortening the interval between shots to something like 10 or 11 days and see if it doesn’t smooth out within a few weeks.
 
I'll tell you this. Test U was causing me high blood pressure, I had to take telmisartan to get it down to 130's/80. I took it for 2 years not changing the ester.

After I have switched back to Test C, my problems vanished after about 2 good months and I felt much better. I still take meds, but my blood pressure is very healthy now.

It's crazy and strange, how different we react. I have only seen 2 guys say the same as I do. They had similar issues.

Yeah I get that, I know with test U it will take a long time to reach stable levels.

I'm just very surprised that I have puffy and sore nips that started after the first dose - if anything I would have expected that my estrogen would be lower because total test at this stage, and at the early stage generally of going to undeconoate will be lower than my stable dose from test E

Or am I retarded?

I have taken some arimidex that I had left over from when I started trt years ago, seems to have alleviated slightly over the course of a week. AIs always make me feel shit generally though - I get a weird sore throat from them.

Reason I changed is I travel internationally all the time with work and can't be fucked dealing with any questions.

I agree with others every fortnight sounds strange. Seems to defeat the purpose of using such a long ester.

any idea why it happened to you mate? did you investigate?

I got higher BP from test E, I've been on Telmi and amlodapine for years now.

Yeah, on paper makes sense what you say. I know I aromatise more on test U than test E, but I aromatise a lot anyway. I just worked out how much aromasin I needed and went from there.

For me the reason why I do test U is to have the stable levels of test E pinning daily, but just pinning once per week while on trt. And for not having to worry about test when I travel.
Then I add test E as needed when I increase the dose for my mini blasts.

Out of curiosity, what carrier oil was the test U in?
