The last time I checkee, they were selling Ald-52 and something else, 1P-LSD I think, as Orange Sunshine. Both were widely available and legal to purchase online. Plus many other knockoffs. I've never tried any (knowlingly at least. I have taken weird shit lol), or the original Orange Sunshine though. The original was way before my time. Most likely the dude just ordered some legal acid from the internet though.
Wiki: Tim Scully has confirmed that the speculation above is incorrect. In a Reddit AMA
[2] with the director of the movie The Sunshine Makers, he says "The Orange Sunshine we delivered was LSD 25. ALD 52 was an ill-advised desperate defense strategy that failed miserably... The story of Orange Sunshine is complicated by the fact that The Brotherhood distributed LSD from more than one manufacturer as Orange Sunshine. "Nick and I made the original Orange Sunshine in Windsor. That was the last lab I worked in making LSD. Ron Stark managed several LSD labs in Europe and most of his output was tableted and sold as Orange Sunshine. At least some of the LSD that his labs made was not pure."
