Testosterone Undecanoate vs. Testosterone Enanthate

[Boka]

Hi! I am currently using 250mg/ml testosterone enanthate a week and I am planning to switch to testosterone undecanoate. According to steroid plotter I would have to use double dosage with undecanoate to achieve the same levels of testosterone in my blood as I did with enanthate.
Is this true, and can someone elaborate? I am assuming this is because of the half life of the ester..
Thanks guys!

get bloodwork done

The undecanoate ester is bigger, so more of the mg is "overhead"/waste, so per mg you get more test with a shorter ester. The longer half life is meaning you will take longer to reach steady state in blood

I plugged in 212 mg of test undeca into the plotter at every 3.5 days to give nearly same blood levels as 125 mg cypionate

You didn't front load test U on there.


It's gonna b low if you didn't bolus dose

Even then may need 10-20% more test U

Moving from Test C to Test U for TRT

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...

On topic what’s the difference between test e and cyp? I imagine virtually no difference.

 

[holy02]

As you say virtually no difference, if you want to go into details in test e you get 70% of the hormone while for test c you get 69% so you get little bit more test in case of enanthate (almost no difference).

In practical terms people usually get bigger pip with test e than test cyp.

Oil side, test e can have higher concentrations without crashing (if you can tolerate it)

Thanks man!

Double? Of course not.

Use this simple method:

TESTOSTERONE UNDECANOATE 100mg

=63mg of actual TESTOSTERONE.

TESTOSTERONE ENANTHATE 100mg

=72mg of actual TESTOSTERONE.

!That comes from the actual leaflet of both, not some BS on the internet.

EXAMPLE

Say you want to use 300mg TE, but you want to achieve the same with TU, so you compensate some extra and take about 360mg TU.

*300x0.72=216
*360x0.63=226

Simple mathematics.

I know and I agree with U but the steroid plotter says otherwise so I'm a bit confused...

It's just a tool to get an idea of peaks/valleys and also helps to frontload long esters or switch between them. Otherwise it is not accurate at all. Besides older version was better and more useful anyway. You are overthinking.

Some anecdotal piece of mind for you.
My total Testosterone on 250mg compared TU to TC:
1342ng/dl (TU once weekly injection, taken 6 days after)
1516ng/dl (TC twice weekly injections, taken 3 days post)

By your logic, I assume you trust steroid plotter more than manufacturer of said steroid?

I did not trust anyone, I gather anecdotal opinions and read various studies and posts to form my own opinion. This is the part of that. Others have said to me like U that I am overthinking it so I guess I'll go with that.
Thanks for valid and conclusive response, I appreciate it.

It's all right. One more importang thing I will say, is that when it comes to TU the biggest difference is not those milligrams, but rather how it stays so leveled (stable) compared to enanthate/cypionate.

When you inject TU you don't get that high like you do with other esters, but you also don't go down low before your next injection. It stays much more even and leveled. So there's that and it's very important to understand.

Should I go for twice a week as I did with enanthate or will once a week be enough?

Once per week is more than enough with undecanoate. You can even extend to every 10 days if you wish, but I myself like once every week as it's easier for me to plan out injections.

What oil is it in? It affects half life too, so if you have mct, sesame grape seed or similar it's 3 weeks, if you have castor it's almost 5 weeks. So you can even do every two weeks.

It's sesame oil. So once a week it is.

Only issue I have with test u is that it takes too long to tinker with the dosage. Even cyp takes me a while to adjust.

 

[Sampei]

Test U you can go once every two weeks if you have castor oil.
