The Verdict
BulkSupplements takes it on our rubric, 92 to 88 on our 0-100 execution score, and holds our Best Value badge in the BCAA scorecard. The gap is almost entirely value, a perfect 25 against 22, at roughly $0.12 a serving against $0.28; transparency splits 23 to 22 and the two tie at 25 on dosing and form and 19 on purity verification. That purity tie is worth reading carefully, because it flattens a real distinction: NOW Sports is Informed Sport certified and BulkSupplements is not, and if you compete under a banned-substance policy that is not a tiebreaker, it is the decision.
In our view BulkSupplements is the right buy for most people and NOW Sports is the right buy for anyone who gets tested. One thing our data says about the category rather than either brand: we grade the evidence for both at C-plus, because isolated BCAAs have limited support once total protein intake is already adequate.

Why This Comparison Matters
Both of these are unflavored, additive-free 2:1:1 BCAA powders, which is the ratio most clinical protocols used, and both are bitter enough that our notes on each tell you to mix them into something flavored. BulkSupplements gives you 5g per serving from three ingredients: leucine, isoleucine, and valine. NOW Sports gives you 5.6g per serving of pharmaceutical USP grade BCAAs, also unflavored, also with nothing added.
The difference that matters is certification. NOW Sports carries Informed Sport certification, the banned-substance program drug-tested athletes need; BulkSupplements is third-party tested with a CoA available on request but carries no NSF, USP, or Informed Sport seal. Both are made under GMP.
On cost, BulkSupplements is about $0.12 per 5g serving from a 200-serving container at $24.97. NOW Sports is about $0.28 per 5.6g serving from 58 servings at $16.09. We scored both on dosing and form, purity verification, value, and label transparency.

How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.
