3. Rgen is the lowest cost producer of p.a----but other can make it! Lly could also make it if they wished to get into the business!
you just also said in another post that you know everything about p. A ????????
cddog-you are obviously a joker, b/c rgen's protein a is embedded in the manuf process of the drugs that use it...it would be extremely expensive and unattractive due to the regulatory hurdles involved for those companies to change their drug manufacturing processes.
you are a proven liar! You try to come across as some sort of all knowing rgen superstar, but to me it appears that you are a dumb illiterate southerner has an inferioirity complex and never graduated high school....doctor friends??? Lmao
