Resveratrol (3,5,4'-trihydroxystilbene) is a polyphenolic phytoalexin. It is a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase.
It exists as two geometric isomers: cis- (Z) and trans- (E), with the trans-isomer shown in the top image. The trans- form can undergo isomerisation to the cis- form when exposed to ultraviolet irradiation. Trans-resveratrol in the powder form was found to be stable under "accelerated stability" conditions of 75% humidity and 40 degrees C in the presence of air. Resveratrol content also stayed stable in the skins of grapes and pomace taken after fermentation and stored for a long period.

thx but are they both as effective? which is better for pct?

I think right now its all trans, but its not a prefix that is mentioned, cause no one wants to buy the old formulations. In my experience its best to buy 98-99% pure, micronized Resveratrol. Purity is the major issue for most people.

Trans-Res works very well in pct another problem with res is it has a low bioavailbilty and that is why we we use Quercetin in out Post Cycle Support. Good luck bro.
