New Test??

I will post this in the lab as well but I figured I'd ask here since it gets much more traffic. I was just viewing my sources new list of powders and I came across a type of testosterone that I have never heard of. Isotestosterone :scratch: ? They had many different esters of this type of test. Undecanoate, Succinate, Ethylcarbonate, Methylcarbonate. Anyone have any experiences with these types of test? If so, do they convert the same way or similarly to the more conventional tests? i.e. prop, enth, cyp? :unsure:

BUMP for info
