I'm guessing it is, I'm wondering if anyone knows for sure?
I believe the long ester creates oral bioavailability problems. Primo ace is used almost exclusively orally, I have never heard of a long chain ester attached to a steroid intended for oral use. I am not stating anything other than my opinion, though.
Anyway if you have access to the powder, why not just brew it up and inject it? Primo enth brews up very smoothly at 200mg/ml.
Andriol is test undecanoate and is supposedly orally bioavailable.
That being said, I don't know about the OP's question.
