You mustn't done much reading about piracetam because everyone complains about the taste - it's impressively nasty, isn't it? (BTW, if you purchased the powder, I guess you noticed the price difference between the powders and the pills; you should have wondered why there was such a price difference and not then been surprised at the taste.) Anyway, what you can do about it:

1. hide it with citrus fruit juices (eg. unsweetened grapefruit juice)
2. cap the piracetam powder (might be a bit expensive if you don't already own a capsule machine and empty pills)
3. 'parachute' (make pills using toilet paper)
