He site injects in the bis, but I wouldn't say for sure that there is synthol present.
well that's true. it seems to be a consistent thing with german guys. heiko, ruhl, marko savoleinan, more i can't think of. they inject their shit in the biceps. makes sense, it's a good place. but if it was serious synthol usage he'd do it in the triceps.
thats my verdict, site injections.
