I think that letter confirms what you were saying early learning curve about it being too expensive.
My interpretation of the letter is that NSF has to test every single batch of the products (except for the musclegel shots mentioned) to mark them officially as NSF. This would mean that every single batch would have to be tested, which costs mucha mulla. The specific batches mentioned for the non-musclegel products are probably held by Muscle Pharm for athletes (probably the sponsored ones) who order directly from Muscle Pharm. All other batches are sold to retailers and online distributors.
However, I really doubt that NSF certification had already cost Muscle pharm a great deal of money since they didn't certify that many batches. I'd say once NSF said wtf are you doing with our labels, Muscle Pharm tried to work out a deal, dragged it out as long as possible (or try to work a deal and ignored the initial WTF letter from NSF), then ultimately got dropped/made the decision to not pursue NSF certification for all batches. Meaning, I don't think this "decision" will lead to many savings since it sounds like they didn't spend too much in the first place.
