   A website for comparing protein powder prices▲122

   diskprices.com, but for Protein Powder! Buying protein powder is a mess, and comparing different products is frustrating, since all brands choose their own serving sizes. By collecting nutrition facts, and normalizing the serving to contain 25 grams of protein, we can properly compare price/nutrients per serving. Inspired by diskprices.com, the idea is to provide an equally functional interface to compare products. The prices are collected once a day, currently from iHerb US. Aiming to improve the coverage soon. Any tips / suggestions / other feedback more than welcome :)…
