I understand that. That is why I inquired.... just looked very similar in structure.
They are extremely similar both in structure and function. Dien-diol is the 3,17 diol prohormone to "Dienolone" another name for Tren is "Trienolone" it would also be accurate to call Dienolone "Denbolone" or "Dienbolone"
Dienolone is 1 hydrogen off from tren. This is because tren had three carbon-to-carbon double bonds whereas Dien only has two. This is where the "di" in Dien comes from and the Tri/Tr part of Trienolone/Trenbolone come from.
What's significant here is that the third double bond on tren is an 11-12 double bond. This bond can, to some degree be hydrolyzed into an 11-OH functional group. Cortisol also has an 11-OH group; because of this similarity, tren can have a profound effect on corticoid hormones which can have string subjective effects/side effects. The absence of this third bond on Dien may explain why some refer to Dien as "Tren with less sides" or "tren-lite"
I may add a third double bond to Dien at some point but in a different place... I'm hoping this will yield a hormone as strong as Tren/stronger than dien but still with fewer side effects than Tren...
Maybe I'll call it NuTren...
