I'd like to try different flavours of protein powders to see which one better suits my taste. However, almost all those sold in shops/online weigh at least 500g, often 1kg or more. Which makes it impossible to try more than 2 or 3 without spending a lot of money and possibly wasting a lot of powder.
How do people actually do it in practice? Do they just try their luck and hope they'll like it? Are there sample bags of miscellaneous flavors with a small amount of each that can be bought? Or do shops offer small amounts for you to try?
(I didn't see any of that at Holland & Barrett, and I didn't go to any gyms, either, in case that's relevant.)
