He did disclose it, and that's how we all can figure that one out:
"Disclosure: I have no positions in any stocks mentioned, but may initiate a long position in OTCQB:MSLP over the next 72 hours. I wrote this article myself, and it expresses my own opinions. I am not receiving compensation for it (other than from Seeking Alpha). I have no business relationship with any company whose stock is mentioned in this article."
For a long time, the Arnold Series was at #10 in popularity, then started slipping in the last two weeks.
Now it is all the way down at #18.
Maybe it is not as popular as it was, but I prefer to think that direct sales on the Arnold website is taking sales away from them. I can't believe that his line of supplements isn't becoming more popular with each passing week.
regardless, I can't resist buying at these ridiculously low share prices. GLTA
