Product details
Where this label sits
BSN Syntha-6 is one of the protein powders in the Scoop Sense database. Every active ingredient on the panel is listed with its own dose — nothing is hidden inside a blend total. It runs 48 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of July 2026 — never from the marketing page.
Key ingredients & studied doses
- Protein Matrix (Whey Concentrate, Calcium Caseinate, Hydrolyzed Whey, Whey Isolate, Micellar Casein, Milk Protein Isolate) · 22 g. Combines fast-digesting whey with slower-digesting casein and milk proteins studied for sustaining amino acid availability after a serving.
Flavors & sweetener
Chocolate Milkshake is artificially flavored and sweetened with acesulfame potassium and sucralose.
Who it's best for
A standard-ratio powder — fine as a food supplement when total daily protein is what matters. Derived from the label figures above — not medical advice.
How we log this label
Every entry is built the same way: we read the current supplement facts panel, log each disclosed dose, compare it against the amounts used in published research, flag proprietary blends, and state the cautions plainly. The full methodology explains each step.
This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice.

What other people say
Why we don't rate productsTwo different things, side by side: the rating the seller publishes on its own store, and what independent users write in public threads. Scoop Sense writes neither and collects no reviews of its own. Neither is evidence that a product works — they describe what people experienced and expected, not what the research shows.

What people actually report
Reddit users consistently praise Syntha-6's taste and mixability, but the recurring point of skepticism is that it's a multi-protein blend rather than a straight isolate, which underlies its long-running amino-spiking reputation and higher price for less protein per serving.
- positive Taste. Commenters across multiple threads single out Syntha-6's flavor as notably better than other whey powders.
- mixed Value vs. plain isolate. Some users say they prefer it for taste but note it costs more and delivers less protein per serving than simpler whey options.
- mixed Protein blend, not pure isolate. Multiple threads point out Syntha-6 is a blend of whey concentrate, caseinate, and other protein sources rather than a straight isolate, the basis of its amino-spiking reputation.
- mixed Composition confusion. Buyers comparing it to single-source whey products note the blend contains added carbs and fats alongside the protein mix.

Common questions about BSN Syntha-6
How much of a BSN Syntha-6 scoop is actually protein?
22 g of protein from a 47 g serving — about 47%. The rest is flavoring, fats, carbs, and whatever else the label lists. A higher percentage means less filler per scoop.
Does BSN Syntha-6 disclose every dose?
Yes — the label lists an individual amount for each ingredient, with no proprietary blends. That is what the "label fully disclosed" tag on Scoop Sense means, and it is what lets each dose be compared against the amounts used in published research.
