Protein

Mass gainers

Powders with lots of carbs plus protein – many calories per shake. They make it easier to eat more than you burn, which you need to gain weight.

28 products from US online stores, sorted by what 30 g of protein costs – not by the price per pack.

What does 30 g mean?

protein per serving in most of the products we checked
16–55 gprotein per serving in most of the products we checked
  • 30 g is a fixed amount to compare by: half of the 28 products we checked have up to 50 g per serving, the other half more.
  • There’s no single daily amount for protein – it depends on body weight: 1.4–2.0 g per kg a day for people who exercise, from food and supplements together (ISSN (opens in a new tab)).

We compare by 30 g only so products line up – it’s not a recommendation. Not medical advice.

Where products miss quality points

How the 28 products score

  • Very good 90+: 13
  • Good 75+: 13
  • Fair 60+: 2
  • Low under 60: 0
have no seal from an independent testing program
54%have no seal from an independent testing program10 of 30 testing points for GMP, 15 for the 2 whose label says “third-party tested”
contain artificial sweeteners
64%contain artificial sweetenerscosts 2 of the 20 additive points

The full 30 testing points need an independent test. Every supplement sold in the US is made under the FDA’s GMP rules – the maker checks its own products, which gives 10 points. A seal from a testing program like NSF, USP or Informed Choice means a lab outside the company checks that what’s inside matches the label. Most brands don’t take part. That doesn’t make a product bad – without a seal, a clean product still gets up to 80.

We find seals on the label and in NSF’s public lists. USP and Informed Choice don’t let us search their lists automatically, so a seal that’s only in their lists can be missing. How the score works

Good to know

Fact
500%more per 30 g for the most expensive product than for the cheapest.

How we checked: one-time price for each size in the store’s US online shop, before sales tax and shipping, without subscriptions or coupons. Prices change often, so check the store before you buy. More on how we check

The amount we compare by only makes products comparable – it is not a dosage recommendation. Not medical advice.

How we calculate

Cost per dose = price ÷ (servings × amount per serving) × comparison amount. Example: $119.99 for 74 servings with 24 g of protein each is 1,776 g of protein. $119.99 ÷ 1,776 g × 30 g = $2.03 per 30 g of protein.
