Twenty-four grams of protein, 5.5 grams of BCAAs and 11 grams of essential amino acids in a single scoop — that combination is why this is the tub we keep reaching for. You get a full recovery dose without doubling up or doing arithmetic at the counter, and the protein comes from whey isolate and concentrate rather than all concentrate. The instantized powder breaks up in a shaker in about twenty seconds, as claimed, and Double Rich Chocolate tastes like chocolate milk rather than like a supplement.
Water is the least flattering way to drink it. At six ounces we found it a touch thin and faintly chalky; at eight ounces, or with milk, that disappears entirely. The sweetness is restrained for a chocolate powder, which matters more than it sounds — a shake you only tolerate is a shake that ends up at the back of the cupboard by week three.
It sat easily with us, but whey concentrate is the usual suspect if you're lactose-sensitive, and that's the one thing worth knowing before committing to a 2-pound tub. If dairy has bothered you before, start with an isolate instead — the Dymatize ISO100 below is the gentler option here and just as easy to drink. The 2-pound size also fits a gym bag and a crowded shelf in a way the bulk tubs don't.
Pros
- Full 24 g dose with 5.5 g BCAAs in one scoop
- Mixes in a shaker in about 20 seconds
- Chocolate flavor that doesn't taste like sweetener
- Banned-substance tested
Cons
- Thin and faintly chalky at six ounces of water
Our default pick: a full 24-gram dose with 5.5 grams of BCAAs, mixes in a shaker without clumps, and tastes like chocolate milk rather than a supplement. If you want one tub that does the job, start here.
