of course it was, manfred hoebrl the strongman, was using the "posing oil" that german guy, Clark, I think, invented around 1990/91
What you have to understand, is synthol is not just the stupid lumps haphazzardly injected like a lot of idiots do. Its injected deep into the tissue, like darrem did, that's why his arms didn't change shape, like priest, like flex, like kevin, same principle as esiclene, but instead of temporary inflammation, what they do is stretch the muscle fascia, by injecting the muscle and training it, thereby accomodating for new localized growth one wouldn't normally be able to achieve.
This is what dex has achieved, what kai has done, heath is by far the best example
the thing is with Darrem---if you seen old pics of him, and followed his natty claims, this dude was one of the Mesomorph78 type of guys, he liked lifting...and this was back in the late 80s, and he turned Pro sometime in the 90s. His arms were never that big, and he was never that big. I don't believe he used it, as it was fairly new on the scene in the 90s, and it was more a Euro thing, until Esiclene supplies dried up...thanks partly in part to Flex And Kev from what I understand. Darrem was too proud of his natty claim as well...plus he had nothing to gain.
The only knock on Darrem was when he had lumps on his calves---something Flex, who knows a thing about Synthol and SEO had noticed.
