I found collagen powder online which contains about as much protein as whey powder – 20g against maybe 23g.

Plus you get benefits from collagen: better skin, hair, nails – or so people who’ve tried it say, at least.

Do my comrades recommend switching to collagen or whey? What are the differences, if any?

I bought a 1kg pack of collagen for cheap so I’ll test and report! Haven’t tried whey yet, I’m starting out lol.
