Alpha-Pharma is one of a handful of steroid producers with origins in the underground who have transitioned (or at least claimed to have transitioned) to legitimate and/or registered companies i.e. Alpha-Pharma Healthcare, Unigen Lifesciences, Balkan Pharmaceuticals and of course everyone's favorite Asia Pharma.
My experience with Alpha-Pharma and Unigen Lifesciences involves negotiating an advertising deal on MESO. (Since they don't sell AAS on their website, it was legal for me to advertise.)
They pre-paid for a six-month campaign for Unigen to be followed by Alpha-Pharma but they pulled it after a couple of months. The reason they gave: the presence on a controversial AAS site caused concern among some of their hospital / pharmacy clients.
