I think you would need 3 standards and three tests, at a cost of about 900 dollars@Millard Baker
With compound blends, or mixes if you will, becoming more popular, would it be prudent to test some of these blended compounds at some point?
For a lab to claim a compound blend of lets say 3 different Tren esters or 3 different different compounds at a particular ratio, it would be both interesting and important to see how close they come or if in fact the 3 Tren esters are in actuality just Tren E.
