Ok this question will probably get answered better but some of the vets who have been in the game for a long time. Just reading around the net like I always do and has come across this form of test. Originally when it first came about it was slightly different but from what ive found now days if you do find someone carrying it,its even more virtually the same as sustanon. So anybody that actually had experience with it,whats your take on it and would there really be an advantage if of using it VS sustanon. I just like to learn and hear opinions on things that are new to me.

Omnadren 250 is an oil-based injectable containing a blend of four different testosterone esters: Testosterone propionate, phenylpropionate, isocaproate and caproate. Being as it is a four-ester testosterone, Omnadren is most commonly compared to Sustanon. While it does contain Testosterone propionate, testosterone phenylpropionate and isocaproate in the same strength as Sustanon, the last ester is different. Please note however, that the older versions of Omnadren list isohexanoate and hexanoate as the final two ingredients. Hexanoate is simply another word for caproate, so the last ester (decanoate) is the only Sustanon constituent missing from Omnadren.
One of the only noticeable differences between Sustanon and Omnadren seems to be the speed in which estrogen buildup occurs. In comparison, the process appears to be slightly more pronounced with Omnadren. This is of course just a matter of timing, as the slowest releasing ester in Omnadren (caproate) is a little faster acting than enanthate. Blood testosterone levels will therefore peak much faster with this compound, not having the same gradual release time imposed by testosterone decanoate
