Review on NutraBio Pure L-Leucine – Enhanced Muscle Recovery and Support – Naturally Fermented Free Form Amino Acid – Vegan, Non-GMO, Gluten Free – 500g by Milagros Iser

I like the trustworthy seals, the convenient packaging and the presence of the scoop. However, one of the small plastic spoons provided should contain 1 serving = 3 g of leucine. The problem is that 1 level scoop just isn't 3g. More like 2 years. And if you're not careful to fill the scoop to the brim, it's more like 1.7, or just over half a serving. In 5 attempts of 3 different measuring methods on the gram scale (crumbly, compact, heaped), everything was averaged. to less than 3 g (2.1, 2.7 and 2.8 respectively). Based on "loose" measurements, the scoop should be about 43% larger; a measuring spoon of 7 or 8 cm3 is suitable for 3 g dry weight.
