Why are the names of the suppliers not shown on the product certificates?

You claim that your product is 100% natural – are the aromas also natural?

All the powders are 100% natural. No additives, coloring agents, aromas, sweeteners etc. For the users who prefer flavored products, we add the aromas, so you can make a shake at your own desired flavor (mixing aromas to make a NEW flavor, adding more or less aroma to suit your taste). Aromas are all natural-based. To improve the flavor we only add a sweetener - sucralose.

How much powder can I mix with 1 Aroma?

One aroma is usually enough for about 2,5 kg of protein powder. For amino acid products 1 aroma should be enough for 2 kg of product. Depending on the desired taste, this information can vary up to 30%.

How many drops of aroma should I add to 1 shake (1 level scoop of protein)?

Depending on how strong you would like the taste to be, you can add between 8-12 drops per 1 sccop and 3 dcl of water. The fun, however, is in creating your favourite mixtures and blends so we encourage you to experiment.

Can I use your products, if I have a lactose intolerance?
