The main muscle ingredients in this whey shake are its amino acids, leucine and L-carnitine, all at or above the studied doses. Across 96 studies of 7,596 people with age-related muscle loss, training plus protein-based supplements gave the biggest gains in strength, walking speed and muscle mass [1]. In 130 older adults who exercised, whey protein with amino acids added 1.7 kg more lean mass than placebo [2]. Not every review agrees: in 763 women, supplements added no muscle beyond exercise alone [3]. Leucine-rich protein supplements improved strength and muscle mass in 699 older adults [4], but leucine taken on its own mostly did not help [5][6]. L-carnitine raised muscle mass in elderly people with fatigue [7] but did not change strength or body makeup in healthy women aged 65 to 70 [8]. Calcium did not build muscle in trials of children and teenage girls [9][10]. Potassium did not raise muscle mass or power in older adults [11][12]. The enzyme blend is below the dose studied, and enzymes did not change lean mass over 90 days [13]. Animal and cell studies are never counted.

Buyers mostly like this chocolate powder, mainly for its taste, how well it mixes and its protein per scoop, though some find it pricey. It carries about 181 ratings across the stores. The reviews all come from one store page, and I found no reviews of other product forms to leave out. **What buyers say it did for them:** Several describe good workout results and recovery. One says it "delivers great post-workout recovery!" Another reports going "from 135 to 205 on bench in a month and a half," though they had also just returned to lifting. One says it "seems to boost my pump." Others call it a good pre- or post-workout shake. **What they complain about:** Price is the main complaint. One buyer says it is "too expensive for the amount you receive vs other manufacturers," and another says "there is better protien out there that is less expensive." One reviewer warned "DO NOT BUY. TASTED CONTAMINATED." Another says they will not order again. One reviewer wanted more calories for weight gain, and one says it can upset the stomach if you go several hours without eating anything else. **Taste, mixing and form:** Taste is the most praised feature. Reviewers say "Great flavor" and "tastes better than any other supplement I've tried." The store summary says the chocolate is compared to chocolate milk, with no metallic aftertaste noted. It goes well with milk or soy milk. Buyers say it mixes well in a blender or shaker cup and cleans up easily. One says three scoops "easily fits in one glass without being too thick." A scoop gives 20g of protein. **Digestion and calories:** Reviewers call it easy on the stomach. One says it is "easier on the stomach," and another had "No digestion isues." One says it "doesn't fill me up, so it's easy to eat a real meal." Others like that it is low in calories, fat and sugar. One says it has "a good ratio of calories to protein content." **Value for money:** Opinion is split. Some call the price fair for the quality, one saying "a pretty good price for quality protein." Another bought again because of "a really good buy one get one deal." Others accept that it is expensive, with one saying "it's expensive, but comes with a lot more protein." Others think cheaper powders do as well or better. Several reviewers say they will buy it again, and one has used it for years. **Who it suits and who it did not:** It seems to suit lifters who want a high-protein, lower-calorie shake that tastes good, mixes easily and sits well in the stomach. It is also suited to people who want to eat a normal meal soon after. It suited less well people watching the budget, since cheaper brands were said to work as well. It also suited less well anyone wanting a calorie-dense gainer, and the buyer who found a bottle that tasted contaminated. Repurchase intentions are mixed but lean positive.

Biohacker Summary

Members Only10 of 10 recommend it
10 of 10 biohackers on our panel recommend it

Amino acids, the main ingredient, get a mostly positive response: four of the ten panelists recommend them, two use them, three are neutral and one warns. Those who recommend them stress getting all nine essential amino acids each day, with one citing 7.6 grams of aminos in a morning drink, and another using them as a faster-absorbing alternative to whey when they want something that isn't milky. Several tie them to muscle building, and one says leucine acts as the trigger, with a sufficient dose needed and the other essential amino acids to keep the signal going. The one caution is that amino acids should not be taken during a fast because the leucine insulin response can shut down ketosis. Leucine, potassium, calcium and L-carnitine are smaller ingredients in this product, and the panel mostly talks about them as separate nutrients for muscle, hydration, bones and fertility.

RAL Summary

Members OnlyTier 4 for Muscle and Strength

The 1479 counted reviews do not fit the review summary, which found only about 181 ratings for this chocolate powder on one store page, so the count likely includes other products. Its reviews are set aside, so it is graded on its studies alone. Human studies support Amino Acids (29 of 48 human studies showed an improvement), but there are not yet enough reviews to confirm it (0).

  • Emerging: not enough evidence to rank higher yet.

Where the evidence disagrees: 35 of the 124 human studies found no effect.

Body systems: Muscular system, Digestive system

Combine with: For muscle building, pair this whey protein with creatine monohydrate (3-5 g daily) to support strength and lean mass, and with beta-alanine or citrulline malate for training performance and endurance. Vitamin D3 with K2 and magnesium glycinate support muscle function, recovery, bone health, and sleep. Omega-3 fish oil (EPA/DHA) helps manage exercise-related inflammation and also supports cardiovascular health. If blood pressure is a concern, discuss with a clinician about dedicated options such as magnesium, potassium-rich foods, CoQ10, or beetroot nitrate, as these are not provided by this product.

Possible side effects: Studies reported no major side effects. One buyer said it can upset the stomach if taken several hours after eating anything else, and another said one container tasted contaminated.
