MR carries the Powdered for and the prediluted form which is best for storage? I would presume that the liquid form would need to be used quite a bit sooner than the powdered form.
I am trying to figure out why the powdered form costs more.
I was wondering the same thing ...
The powdered form probably would be better for long term storage, but MR has gone from a BA to AA solution, so the prediluted should be even more stable. I think the powder is from a different lab also. Check out this thread: IMPORTANT IGF NOTICE!!!
