The short version
- One 32 g scoop: 25 g protein, 120 calories, 1 g fat, 2 g carbohydrate, 1 g sugar and 180 mg sodium, per the Nutrition Facts panel on Dymatize's product page.
- $109.99 on Sep 30, 2026 for the 5 lb tub (71 scoops), sold by Amazon.com: about $1.55 per scoop, or about 6.2 cents per gram of protein.
- The listing images show the Informed Choice mark, which is about banned-substance testing, not about whether the powder works. It contains milk and soy, and "filtered to remove excess lactose" is not the same as lactose-free.
Not a workout tool.
The quickest way to put 25 g of protein into a meal that has almost none.
Often drunk right after a session; a meal within a few hours does the same job.
What the label shows
We read the Nutrition Facts panel, ingredient statement and amino acid table on Dymatize's product page for the Gourmet Chocolate flavor, and the ingredient text, warnings and label photos on the Amazon listing for the 5 lb tub, on September 30, 2026. A serving is one scoop (32 g); the tub says 71 servings. Percent Daily Values are the FDA label values based on 2,000 calories a day [1].
| Ingredient | Amount per serving | What to know |
|---|---|---|
| Calories | 120 | Of those, 100 come from the 25 g of protein at 4 calories a gram. Very little else is in the scoop. |
| Protein | 25 g (50% DV) | Dymatize's footnote: "100% of the protein from whey protein isolate," part of it hydrolyzed (see below). Half the 50 g label Daily Value in one scoop. |
| Total fat | 1 g (1% DV) | Saturated fat 0 g, trans fat 0 g. Isolate filtering removes most of the milk fat. |
| Cholesterol | 10 mg (4% DV) | Small; it is a dairy product. |
| Sodium | 180 mg (8% DV) | Less than half the sodium of the Orgain plant powder per serving. |
| Total carbohydrate | 2 g (1% DV) | Dietary fiber less than 1 g; total sugars 1 g; 0 g added sugars. The sweetness comes from sucralose (and, on Dymatize's current label, stevia). |
| Calcium | 120 mg (10% DV) | Comes along with the whey. Potassium 230 mg (4% DV), iron 0.8 mg (4% DV), vitamin D 0 mcg. |
| BCAAs / leucine | 5.5 g / 2.6 g ("typical") | Dymatize labels these as typical amounts, not guaranteed panel lines. The leucine figure sits inside the 700 to 3,000 mg per-dose range in the ISSN position stand [2]. |
The ingredient statement on Dymatize's page reads: hydrolyzed whey protein isolate, whey protein isolate, cocoa powder (processed with alkali), and less than 2% of salt, soy lecithin, natural and artificial flavor, potassium chloride, sucralose and steviol glycosides (stevia). Contains: milk and soy. The Amazon listing's ingredient text is an older version that says "less than 1%" and lists sucralose without stevia, and Amazon's own note on the page says the panel on the tub you receive "may vary slightly." Read the tub. Amazon's product details list it as gluten free; the Dymatize pages we read did not say so in the text, so that one stands as the listing's claim, not the maker's.
The two words on the front. "Isolate" means the whey has been filtered further than a standard whey concentrate, which is why the panel shows 1 g of fat and 2 g of carbohydrate; Dymatize describes it as "filtered to remove excess lactose, carbs, fat, and sugar" [4]. "Hydrolyzed" means part of the protein has been pre-cut into shorter peptide chains, which the maker markets as faster absorption. The ISSN position stand notes that whey isolates and hydrolysates are the most studied proteins around resistance exercise, largely because of their essential amino acid and leucine content, but it does not claim that hydrolysates produce a practical advantage over plain isolates [2]. In plain terms: the hydrolyzed part is a manufacturing detail, not a reason to pay more.
The testing mark. One of the Amazon listing images shows the Informed Choice mark under the words "Banned substance tested," and Dymatize's ISO100 page repeats "Banned Substance tested" [4]. (The front of the tub in our photo does not show the mark.) Informed Choice is a program that tests supplements for substances banned in sport; Dymatize's own listing image describes the tester as a "world-class sports anti-doping lab." It is not the same as Informed Sport (a separate program from the same certifier), not the same as NSF Certified for Sport, and it says nothing about whether the product does anything. The certifier's public directory shows an entry titled "ISO100 Hydrolyzed Protein Powder (USA)" under Dymatize Nutrition in search-engine listings, but the directory page itself blocked our automated access on Sep 30, 2026, so we credit the mark on the strength of the listing image plus that indexed directory title, not on a directory page we could read ourselves.
What the evidence shows
Where 25 g fits. The ISSN position stand suggests people who exercise regularly land between 1.4 and 2.0 g of protein per kilogram of body weight a day, spread into doses of about 0.25 g/kg, or 20 to 40 g, every three to four hours [2]. One scoop is a textbook single dose for most adult body weights. For someone who does not train, the baseline from the National Academy of Medicine is 0.8 g/kg, about 50 g a day for a 140 lb adult, and Harvard's Nutrition Source notes that many people in the US already reach that from food [3]. If your meals already contain eggs, dairy, meat, fish, beans or tofu, a scoop may be solving a problem you do not have.
Whey against plant protein. The same ISSN stand describes dairy and animal proteins as carrying more essential amino acids and more leucine per gram than plant proteins, and describes soy, although complete, as a lower-quality protein than milk proteins in the studies it reviews [2]. That is the honest case for whey. The honest case against it is that it is milk, and a fair number of people do not digest milk well.
Timing. The label tells you to drink it "within 30 minutes after workouts," and the marketing leans on speed. The ISSN stand's own key point is that total daily protein and calories matter most, that timing right before or after exercise has a minimal extra effect in non-athletes, and that muscle stays responsive to protein for up to 24 hours after a session [2]. Drink it when it is convenient.
Safety. The ISSN stand reports that published reviews find no indication of kidney or liver harm from higher protein intakes in active people, and cites trials in healthy, resistance-trained adults eating roughly 3.3 to 4.4 g/kg/day for eight weeks to a year that found no harmful effects on the blood markers measured [2]. That statement is about healthy adults. Anyone with a kidney concern, or on medication, should ask a clinician before adding a high-protein powder. Harvard also notes that, like other dietary supplements, protein powders are not regulated by the FDA for safety [3].
This is milk. It contains milk and soy (lecithin), and "filtered to remove excess lactose" means less lactose, not none. Five pounds is a 71-day supply at one scoop a day and the listing is non-returnable, so if you have never used it, the listing's own variation menu offers smaller chocolate tubs to try first. Ask a clinician before using it if you are pregnant, nursing, take medication or have a kidney concern.
How to fit it into a simple week
A sequence for using the tub without letting it run your kitchen; not a promise about outcomes.
Count before you scoop
Add up a normal day's protein once (our protein basics routine walks through it). If the gap is 20 to 30 g, one scoop closes it. If there is no gap, put the tub away.
Mix one scoop in 5 to 6 oz
That is the label's own direction and it mixes thin, more like chocolate milk than a milkshake. Water keeps it at 120 calories; milk adds its own protein, sugar and calories, so decide which you want.
Put it where the gap is
Breakfast on a rushed morning, or after a session on the days you train. Either slot is fine; the day's total matters more than the clock.
Keep the tub honest
Seventy-one scoops should last about ten weeks at one a day. If it is going faster, you are drinking calories you did not plan; if it is going slower, that is fine too.
Price and where it is sold
On Amazon we saw $109.99 on Sep 30, 2026 for the 5 lb (2.3 kg) Gourmet Chocolate tub, ASIN B002N6F2UW, shown as "In Stock" and "Ships from and sold by Amazon.com." Amazon's own unit price was $1.37 per ounce; by scoop that is about $1.55, or about 6.2 cents per gram of protein, against about 7.6 cents per gram for the Orgain plant powder on the same day. The listing's product title says "76 Servings," but the tub photo and the product-details table both say 71, so we priced it on 71. The listing carries a "non-returnable due to food safety reasons" notice, with refund or replacement only if it arrives damaged or defective. The same listing offers 1.34 lb and 3 lb chocolate tubs and other flavors through its variation menu. These are the numbers for that date only.
Who should look elsewhere
- Anyone with a milk allergy or who avoids dairy; the Orgain plant protein entry is the non-dairy option on this site.
- People with a soy allergy, since soy lecithin is in the ingredient list.
- Tested athletes who specifically need NSF Certified for Sport or Informed Sport; this product carries Informed Choice, a different program.
- People who avoid sucralose or artificial flavors.
- Anyone who is pregnant, nursing, takes medication or has a kidney concern should ask a clinician or pharmacist first.
