Does anyone out there have experience with injectable Testosterone Undecanoate? I got a few bottles of this stuff dosed at 500mg/ml. Info on injectable Test U is harder to find than Test C since most of the info I can find after a Google search is really about Andriol pills - not injectable Test U. So I've got a few questions.

1. Is 500 mg/week Test U going to really be equivalent to 500mg/week Test C? I read it can be weaker than other Test esters mg/ml so I'm curious if I need to dose a little higher. I've been searching for days but can't find the reference where I read this - it's driving me nuts. Do I need to boost this to something like 550mg or 600mg/week for the same effect?

2. How long after my last Test U should I wait until I start PCT? I've got conflicting info below - My best guess was probably 3 weeks but the Steroid .com active life of 3 months for Test U - compared to active life 15-16 days for Test C really has me concerned. No way will I use this stuff if I need to wait 3 months after my last pin to start PCT.

3. I normally pin 2x/week but here the 1/2 life of the esters of both injectables are even longer than Test C so can I reduce my pinning schedule to inject every 5-6 days or maybe just once/week & keep relatively even Test levels?


My Info:

Age: 34
Height: 5' 10"
Weight: 195 lbs
BF%: Not sure - but quite low

I'm an ectomorph (was only 145 lbs out of college). I train 4-5 days/week, lots of jiujitsu + weight training.

Cycle Experience (3):

500mg/week test E weeks 1-12
PCT

500mg/week Test C weeks 1-12
40mg/day Dbol weeks 1-4
PCT

500mg/week Test C weeks 1-15
40mg/day Tbol weeks 13-17
PCT


Research:

Ester 1/2 life found here: Please do not post outside links *admin*

Test Cyp: 12.0 days
Undecanoate Ester: 16.5 days
Deca (Nandrolone decanate): 15.0 days

If this is right I would think to run my cycle like this (Test & Deca front-loaded at double dosage - 1st week only):

Test U*: 500 mg/week weeks 1-12
Deca: 400 mg/week weeks 1-12
Arimidex 0.5 mg/eod weeks 1-14
T-bol**: 60 mg/day weeks 10-14
Nolva 20 mg/day weeks 15-20
Clomid 50 mg/day weeks 15-20

*I realize that without a kick-start & using such long esters it's going to take maybe 3-4 weeks to really get going. With Test C I start to feel it in about 2 weeks.

** I like t-bol because d-bol gives me major sides (acne like crazy).

Conflicting info here. http://www.steroid.com/steroid_profiles.php

Active life Deca: 15 days
Active life Test C: 15-16 days?
Half-Life Test U (Nebido): 3 months?!

Thanks in advance fellas.
