Pure Protein is the value play, plain and simple: 21 grams of mostly-complete dairy protein for roughly $1.30 a bar, the best price per gram of protein in this entire lineup and a fraction of what David or Legion cost. If budget is your binding constraint and you just need convenient protein, it does the job. The honest caveats are why it sits at the bottom rather than the top: it leans hard on maltitol and maltitol syrup — the sugar alcohol most likely to cause gas and stomach upset — uses hydrolyzed gelatin as a binder, and tastes more processed than the bars above it. For the cheapest 20-plus grams in bar form, though, nothing here beats it on cost.

Read the complete Muscle Growth guide →21 g of mostly-complete dairy protein — milk, whey isolate and whey concentrate — which clears the ~20 g MPS-maximizing dose (Moore 2009). The catch is a hydrolyzed gelatin binder (an incomplete protein), so a small share of the count is padding; the majority is real, usable dairy protein.
The weakest ingredient deck among the picks: it leans hard on maltitol and maltitol syrup — the sugar alcohol most associated with gas and GI distress — plus sucralose and a hydrolyzed gelatin binder. 3 g sugar reads fine, but the sweetener and binder choices are why this axis scores low.
~$1.30/bar for 21 g is about $0.062 per gram — by far the best price per gram of protein in the lineup, roughly a third of David's per-gram cost. As SAC policy states plainly, powder and whole food still beat every bar, but among bars this is the value leader.
Chewier and more processed than the bars above it — perfectly edible, but it tastes like the budget option it is. Fine for the price, and not a reason to buy or avoid it on its own.
Non-weighted SAC transparency gate. The maltitol load and hydrolyzed gelatin binder are disclosed on the panel, but the '21 g protein' includes the gelatin binder, so a slice of the count is incomplete protein — a modest honesty knock, in line with its bottom-of-lineup placement.
“21 g of protein.”
The bulk is mostly-complete dairy protein — milk, whey isolate and whey concentrate — which is genuine and usable. But hydrolyzed gelatin, an incomplete protein, is used as a binder, so a small portion of the 21 g does less muscle work than the number implies. Mostly real, partly padded.
“Cheapest / best-value protein bar.”
At ~$1.30 a bar for 21 g — about $0.06 per gram — it is unambiguously the best price per gram in this lineup, a fraction of David or Legion. The value claim is fully accurate and the basis for the 'best budget' badge.
“Low sugar (3 g).”
The 3 g sugar figure is accurate, but the low number is held there with a heavy maltitol and maltitol-syrup load. Maltitol is the sugar alcohol most likely to cause gas and GI upset, so '3 g sugar' is true while understating the sugar-alcohol burden.
“Good source of protein.”
At 21 g of mostly-complete dairy protein it clears the ~20 g that maximally stimulates MPS (Moore 2009), so as a functional protein dose it delivers — the ingredient quality, not the protein amount, is what holds it back.
At about $0.06 per gram of protein, Pure Protein is roughly a third the per-gram cost of the premium bars and cheaper than every other pick here. If budget is the binding constraint and you just need convenient protein, this is the honest answer.
Pure Protein holds its 3 g sugar with maltitol and maltitol syrup — the sugar alcohol most associated with gas and GI distress. That's the single biggest reason it ranks last despite strong price and a solid protein count; sensitive stomachs should be cautious.
Hydrolyzed gelatin — an incomplete protein — is used as a binder, so a slice of the headline count is padding. The majority is real dairy protein, so it's not the collagen-heavy story Barebells tells, but the number is slightly softer than it looks.
Per SAC policy, price is a tie-breaker, not a trump card: Pure Protein wins on cost but its ingredient deck is the weakest here, which is exactly why it's ranked #8, not near the top. Buy it when budget rules; step up to Quest when it doesn't.
Pure Protein is the budget pick, plain and simple: 21 grams of mostly-complete dairy protein for roughly $1.30 a bar, the best price per gram in this entire lineup and a fraction of what David or Legion cost.

The honest caveats are why it sits at the bottom rather than the top: it leans hard on maltitol and maltitol syrup — the sugar alcohol most likely to cause gas — uses hydrolyzed gelatin as a binder, and tastes more processed than the bars above. Quality still outranks price on this page, so it's #8; but for the cheapest 20-plus grams in bar form, nothing here beats it.

Total daily protein drives muscle gains. A cheap 21 g bar is a perfectly valid contribution toward that daily total — the bar's job is convenience, and Pure Protein does it at the lowest cost here.
Aim for ~0.4 g/kg per meal across ≥4 meals to reach ≥1.6 g/kg/day. A 21 g Pure Protein bar covers one distributed feeding cheaply when whole food isn't around.
