Nutrition face-off: protein, calories, fat, carbs, and BCAAs
At-a-glance macro breakdown
Quick side-by-side of what matters for recovery and body composition:
Optimum Gold Standard (Double Rich Chocolate): ~24 g protein, ~120 kcal, ~1 g fat, ~3 g carbs, ~1 g sugar, ~5.5 g BCAAs (naturally occurring).
Dymatize ISO100 (Chocolate Peanut Butter): 25 g protein, <120 kcal, 1 g fat, 2 g carbs, 1 g sugar, 5.5 g BCAAs (listed); 71 servings per 5 lb tub.
Isolate vs. blend — what that actually means
Optimum Gold Standard is a blend (Whey Isolate + Whey Concentrate + peptides). Dymatize ISO100 is primarily hydrolyzed whey isolate — higher purity, lower lactose, and fewer carbs/fat per scoop.
Isolate (ISO100): faster absorption, gentler on lactose-sensitive stomachs, more protein per gram.
Blend (Gold Standard): slightly slower digestion, contains more intact whey concentrate and naturally occurring carbs/sugars, still excellent for general use and often cheaper per scoop.
Why BCAAs, calories and scoop counts matter
BCAA content helps stimulate muscle protein synthesis; both list ~5.5 g BCAAs, so recovery potential is similar per scoop. Protein purity (isolate) gives a leaner macro profile — useful if you’re cutting.
Cutting: ISO100’s lower carbs and slightly higher protein-per-calorie make tracking easier.
Bulking/Everyday use: Gold Standard’s blend is fine and often more wallet-friendly.
Tracking note: scoop weight and servings per tub affect daily totals — check the label; Dymatize lists 71 servings, 5 lb tubs of Gold Standard are typically ~70–75 servings depending on scoop size.

Choose this if you want a cost-effective, good-tasting daily whey with many flavors and solid macros. Opt for this when value per serving and flavor variety matter more than having a pure isolate.
Pick this if you prioritize pure isolate macros, minimal carbs/sugar, and fast absorption for post-workout gains or cutting phases. Choose the premium isolate when digestion, minimal lactose, and lean macros outweigh cost per serving.
Taste, texture & mixability: Double Rich Chocolate vs Chocolate Peanut Butter
Flavor profiles & sweetness
Optimum Gold Standard — Double Rich Chocolate: classic, slightly creamy chocolate with moderate sweetness and a familiar milk-chocolate vibe. It’s made to please wide audiences, so expect a rounded chocolate that’s not aggressively sweet and leaves a mild cocoa aftertaste.
Dymatize ISO100 — Chocolate Peanut Butter: lighter, cleaner chocolate base with a distinct peanut note. The peanut is noticeable but not overpowering; sweetness is more restrained and the finish is less lingering than Gold Standard’s. If you like a faint nutty twist without syrupy sweetness, ISO100 delivers.
Texture, mixability & mouthfeel
Gold Standard: creamier mouthfeel thanks to whey concentrate and instantizing. Slightly thicker in milk, can get a tiny bit foamy in a shaker but rarely chalky.
ISO100: thin/clean isolate texture that feels lighter on the tongue. Dissolves extremely well, low foam, minimal chalkiness — especially with water.
Mixing tips:
For a quick hit: water + ISO100 (clean, low-calorie shake).
For creaminess and calories: whole milk or oat milk + Gold Standard (makes a dessert-like shake).
Smoothies/blender: both work fine — use blender for frozen fruit, bananas, or nut butters to avoid lumps.
Shaker bottle: OK for both; shake 20–30 seconds, tap the lid to reduce foam.
To reduce sweetness or mask aftertaste: add unsweetened cocoa, a half banana, or a tiny pinch of salt.
Flavor variety & buying guide
Protein & sugar: Gold ≈ 24g protein, ~1g sugar; ISO100 = 25g protein, ~1g sugar.
Price per serving (approx.): Gold $83/5 lb ≈ $1.10; ISO100 $92/5 lb (71 serv) ≈ $1.30.
Quick buying guide:- Pick Gold Standard if you want creamier, more classic chocolate and better value.
- Pick ISO100 if you want a cleaner isolate mouthfeel, distinct peanut note, and faster digestion.
Price, servings & real-world value per scoop
How to judge cost-effectiveness
Basic math: Price-per-serving = (Amazon price) ÷ (number of servings on the label).
Dymatize ISO100’s 5 lb tub lists about 71 servings. Optimum Gold Standard’s 5 lb tubs generally give a similar serving count (roundabout the low‑70s). Plug the current Amazon price for each tub into that formula to get a true apples‑to‑apples cost per scoop.
Relative positioning — what to expect
Dymatize ISO100 is positioned as a premium isolate and typically shows a higher price-per-serving than Gold Standard.
Optimum Gold Standard is usually the better “value” if you prioritize overall cost and a creamy blend.
ISO100’s higher price reflects purer isolate, hydrolyzation, and lower carbs/sugar — factors some users happily pay extra for.
Value beyond raw price
Faster absorption, higher protein purity, and lower sugar/carbs in ISO100 can justify a higher per-serving cost if you’re cutting, training fasted, or need gentler digestion.
Gold Standard gives more bang-for-buck for general recovery, meal supplementation, and flavor variety.
Quick buying guide
Buy Gold Standard if your priority is lowest cost-per-scoop with solid taste and a balanced macro profile.
Buy ISO100 if you need ultra‑low carbs/sugar, rapid absorption, or have stomach sensitivity and are willing to pay a premium.
Tip: Always check the current Amazon listing, note the exact serving count, and calculate price/serving before you click “Add to Cart.”
