Understanding Testing Results

Here's my question, when looking at the rest reports and there are three different weight measurements for the same batch number, would you just average out the three to get your total MG's in the vial?

yeah average them out. Thats what we do. You will never see a perfect fill or the same numbers across the board. What we dont want to see is +/- 10% or more.

@mrjoshua44 The other thing to consider is how precisely you can actually reconstitute. Say you would have added 1ml if this vial truly was 10mg. If you average those out you get ~11.36mg. So in an ideal world you'd want to add 1.136 ml to reconstitute. I don't know about you... but I can't get to 1/1000th of a ml reliably

@PeptideEd Yeah, but you can easily simplify this by figuring out where you want to get to and backing into it. If you want to get to 1mg, you just reconstitute with the same 1ml, round to 11, and at 91 units you’re getting ~1.032 mg per shot. I tend to be very precise in doing my recon math, but at the same time, when I am arguing with friends over whether they should research 5 units or 6 units, we’ve gone overboard and should either add more bac water(if possible) or worry about it less. (If a difference of 1 unit is going to make you sick or otherwise impact our research, imo, we should definitely be taking a step back to reconsider our process.)

The good thing about this is that you can adjust the math a few different ways to get as precise as you want to if you don’t mind a little more work on the front end.
