Testosterone undecanoate

Yuiserr · 2025-08-17T03:07:03-0400

Hey so long time lurker of the forum first post here as my questions are usually answered here.
Has anyone taken test undecanoate at doses of 750 mg or 1500 mg once a week for 4/6 weeks?
I found ppl saying it’s great for cruzing but they only take 500 every other week. Some at 3/400 weekly but haven’t found anyone taking high doses. I’m wondering if anyone has done it and could provide some insight on it or knows that it is dangerous.
Half life ranges from 16-52 days from different sources but anecdotal evidence on multiple forums say they experience a crash around the 14/16 day mark and another at 4 weeks.
It’s the only thing available for me atm I can but some cream for a bit more money but the convenience of once a week plus the cream goes on the

for the absorption so not the most convenient but doable.
Any input is appreciated

How can they usually be replied to if it's your first post? Plus it says long time lurker and 'new member'. Which is it?

Why, when it's got one of the longest esters would you want to run it like a short to medium estered product?

it was designed to be taken a larger amount more INFREQUENTLY. so you would take it once a month max. a lot of people take it once every 2-3 months even.

i would use it for trt only where you are 100% not coming off. i would not use it for cruising cause when you come off it will be in your system a long time
