Nebido (testosterone undecanoate) in the US.

I know that it isn't approved by the FDA, I was just wondering if anyones HRT doc was importing and making available directly for their own clients here in the US yet.

Bump

Are the shots bothering you?

I don't see that much difference between it and Cyp/Enan.

Besides just a few days longer injection schedule.

30 day half life, quaterly injections is what they are doing in EU, marcus confirmed this. I could see monthly.

Right now I am twice a week.

I have heard of it's half life being around 16 days.

Compared to Test E & C entire active life being 11-14 days that looks pretty good.

Looks like half life is between 16-21 days.

Meh, it looks like every two weeks is all you really can do. Manufacture has been quite deceptive with the every 10-12 week marketing. They claim normal ranges with 10 week shots. Um, so 300-1100 is normal. I don't want to be at 1100 and then at the end of the 3 months at 300.

What a rollercoaster ride that would be. I would rather stay with weekly sticks than have that range of highs and lows. I would venture to guess that by day 10 you start to slide down and day 14-16 you would be begging for a shot. First five days would be a hell of a ride though.

could this be used with additional sustances to help with the tail off near the 10th week

Not sure what you are asking.

**ruffcute** · 03-27-2009, 05:42 PM

I dont, I just have to get the injection soon and have a box of testogel that i wont need

**ruffcute** · 03-27-2009, 05:43 PM

**zaggahamma** · 03-28-2009, 07:29 PM

same reason as above....had it left over from when i was just on gel and actually still have a little

**scubadoo** · 04-05-2009, 09:36 PM

i got this stuff in ecuador right from a drug store... works good.. but its a 4 mil dose.. so i have to shoot twice anyway.... good yes does it blow away cyp? not.

i think it would be great if it were avail here for your doc to give it to you, but dont worry your not missing too much...

Looking at one study (I only have the abstract) a terminal elimination half-life of 23.7 days was reported for testosterone undecanoate. The mean residence time was 23.0 days (for the 1000mg dose). First, with terminal elimination half life of 23.7 days, you don't calculate when the serum level will be halved until after pseudo-equilibrium is established, which is probably about one week. Serum levels reached near twice the high end of the normal level in men so that 29 days after injection, levels were probably at the high end of normal. After another 24 days the level should be right at mid range for the subjects studied. That's 53 days, 7 1/2 weeks. Given this information, a ten week interval is quite reasonable, especially when one considers the risks of accumulation. See Zhang, et. al., J. Androl. 1998 Nov-Dec;19(6):761-8.
