You're referring to Syntherol,it's been popular in competitive bodybuilding since the mid-2000's. There's a detailed science behind it but I won't get into all of that..but basically,it's a site-enhancing oil that stretches the fascia tissue when injected directly into the muscle belly. It's primarily used for a lagging bodypart before a BBing contest and is temporary.

The original site enhancing compound was an Italian drug called Esiclene and it produced temporary swelling when injected into the muscle but was water based unlike Syntherol. Thats been around since the 80's but was never really popular and extremely hard to get.

Thanks for the explanation. The dudes in the second video are using Potenay B12.

I was cringing too much to watch the vids lol,people will do some crazy things to look good in their eyes. Personally I thinks its just ridiculous and looks absolutely dumb,I don't think any ladies are gonna look their way and say to themselves,"you look so hot,take me here&now"

Gregg Valentino was the 1st to achieve notoriety from site enhancing,I remember back in the day the guys on the BB'ing forums that Gregg was on would rip him to shreds lol...his arms "exploded" and that made news headlines all over smh

I’ve done two autopsies on men who have chronically used this and it was terrifying. Imagine a steak, cooked rare, but then mixed with paving concrete. Microscopically the muscle fibers are just obliterated and each section has sheets of granulomas (balls of scarring inflammation that never go away). Both also used anabolic steroids and had such profound heart disease I was shocked they made it as long as they did.
