They're very different structurally...
Allyl trenbolone, aka altrenogest you're talking about?
Structurally I'd expect them to be very similar actually as the only difference should be the ester attached to the actual molecule which is rather small. 3 carbon atoms.

Lol don't make me come at you bro!
I haven't looked at organic about 7 years google doesn't recognize propionyl as an ester....hmmm
Pm me GSracer if you want to know what I think is going on.

Proprionyl trenbolone
I have a feeling that the allyl will cause problems with binding to the AR. Would be a bad one for gains I feel.

You posted the same structures for each it looks like from my phone. Where did u find the structure from ptren?

That's what they say on PHF...

You're right, I searched google images for ptren and it was the first result. Probably should have checked!
This is the propionyl ester (3 carbons!), attach that to trenbolone and you've got it.

What type of functional group is propionyl? Where getting somewhere now.

It is common practice for US pharmaceutical companies to add a bullshit compound to an existing drug to deal with a patent expiration. Then, they can re-market essentially the same drug under a new name.
Bravo to Colochine for recognizing that propionyl tren is the same thing as allyl tren. It looks like the underground market has been taking lessons from Merck, Pfizer, Schering and all the other behemoths out there!

Thanks GS!! When you look at the compound of a structure their are endless possibilities at how to name them.

Propionyl and allyl are different groups! I'm not familiar those specific types of tren though. Best bet would be to look up studies of the effects on animals (as these are both veterinary compounds). I wouldn't be hopeful though, they seem to be used for fertility and such.

Propionyl is an Allyl.
