This is my first review, just sayin.
I just finished my first tub of Promasil by Rivalus Vanilla Flavored.

Taste: First off I loved the vanilla flavor I dont know about you but I'm so sick of chocolate flavored protein.

Use: I'd take 2 scoops a half hour before i fell asleep. Since their is virtually no carbs and sugar it was easy to fall asleep after ingesting it. Note:(also was taking a mass gainer post workout.

Effectivness: I noticed that after starting to take this product every night before bed i started to bulk up/while cutting quicker and saw a lot more strength gains in my routines.

Price: I bought mine at gnc when it was a buy 1 get one 50% off so not that bad but still a little pricey.

Overall: This is probably my favorite protein i have ever taken. I love the taste and that i could easily fall asleep after taking it. And saw more size and strength gains in the gym. The only problem is the cost but I will try to afford this product from here on out.

Good Taste, easy mixability,lean muscle gain, no side effects.This is my first Rivalus product, and I love it. I reallly like that it has no carbs and it has very low fat.
My muscles are a lo less sore the day after workouts. I am an endurance runner, it has help me to maintain lean muscle wile dropping some body fat.
I still recommend it to anyone.

Best protein I have taken so far.
A little to pricey.

I had a terrible stomachache after taking this product. Not good!!! I've taking many proteins and never had that problem so it's not me. I don't know what they use but whatever it is they should check what make it such a stomachache.

This is a Zero Carb Protein. So i decided to try it comparing it to Isopure zero-carb protein.

Content: 9
This protein is a blend of egg albumen, milk Protein Isolate, whey protein hydrolysate, and calcium casein, goat milk Protein Isolate and Beta Alanine. The last 2 really caught my attention, so I decided to try it.

Each scoop contains: 90 calories, 20 grams of protein and zero carbs.

Taste:7
I bought the chocolate flavor and it wasn't the best but it was ok. The best chocolate flavor I have tasted was pro-complex rich chocolate and it was not even close to it but it was drinkable.

Mixability: 7
I must say the mixability was terrible but we must keep in mind that the blend has casein in it and we know casein does not mixes well at all. I usually drank it in my blender bottle and I had to mix it like a BCAA. I had to shake it a few times and just left it in my locker while I showered and it was fine by the time I came back.

Price: 8
I bought this protein during gold card week at GNC. It was $33 for a 2.3 lb tub ($14 per lb), but I got 20% off dropping the price to about $27. Compared to Isopure zero-carb it was not a terrible price.

Effectiveness:
I have to say that this was a very good protein overall. You can't really feel protein working in your body, but it did the job. I am currently cutting and this protein helped me maintain my muscles while cutting fat.

Comparison:
I decided to compare it to Isopure zero-carb since it was the reason I picked it up. These are the stats based on one scoop since it will be the fair way to compared rather than serving since Isopure's serving is 2 scoops.

Promasil/isopure zero carb

calories 90/200
carbs 0/0
fat 1g/0
cholesterol 1g/ 0
sodium 7g/ 16g
Protein 20g/25g

Types of proteins:
Promasil: egg albumen, milk Protein Isolate, whey protein hydrolysate, and calcium casein, goat milk Protein Isolate

Isopure:Ion-Exchange Whey Protein Isolate

Overall: 9
I will pick up this protein any day over Isopure when looking for a protein without carbs (cutting). The price is very similar per pound, but I can get a discount on this protein when Isopure is very expensive and you can not really get discounts on it.

I also like the blend of proteins compared to just one type. I used GNC's website to compare the content of both proteins.

This is a great protein for meal replacements.I noticed in my third week of taking this my recovery was a whole lot better and my muscles never spazzed out at the gym with all the Super Sets i do. the chocolate tasted pretty good and iv heard to stay away from vanilla. its 90 calories per scoop, Zero carbs!!!!!!!!!! 1 gram of fat i think, and its 7 different types of protein, slow,medium, and quick acting. perfect anabolic protein and its perfect for anybody dieting or just staying anabolic all day, i mixed this with a scoop of Wheybolic first thing in the am. then i did the same thing pre-workout and then just 2 scoops of it by itself before bed . on my days off from gym i took it like that before bed and morning. interesting fact about the guy who made this protein, he left muscle tech because they were raising the cost of their products and reducing the more expensive factors of the supplement and replacing it with fillers.

Recently I have been working out to cut size and maintain muscle tone. Promasil is a great product to achieve what I'm looking for because its low-carb/calorie formula enables me to use it as a meal replacement and not feel as hungry post-workout.
My strength and endurance haven't suffered either and I feel as energized post-workout as before I went. I dont use more than 1 scoop per workout since it can become costly but besides that I have no other complaints.

I've been using this for over a year now and finally getting to my review. Let's start by exposing the worst thing about Promasil. It's a proprietary blend, which means there is no real way to tell how much of each ingredient is in the mix. This is the primary reason for an overall rating of 7. Now that we've talked about the worst, let's have a look at why I've been using this product for a while now.

The reason I tried this protein was because of the low calories, stevia sweetening, and added beta-alanine. These, in however small amounts, plus the label, which claims that this is the best absorbing protein on the market.

The results were fairly straight forward. I found that the day after my lifting I was not as sore. When I took it after cardio, I felt like I could head right back out again. Since I began using Promasil I've actually added a workout day to my week.

I was also more capable of handling my calorie intake. When I had a shake in the morning I wouldn't be as hungry throughout the day. I think the blend of casein and whey is working here and that is good news. As an endurance athlete, I cannot afford to gain or lose weight significantly. This product is great for weight management or a cut.

After the first tub, I stopped using this stuff because of the price. I had already tried isolates so I went with BSN's synthia-6 and was not impressed, so here I am back with the expensive stuff that works.

I should also point out that this protein blend isn't really made for bulking. Not enough protein, not enough calories. If you wee going to try and bulk with it, you'd be doing 2-3 scoops per shake and watch your wallet get lighter and lighter.

Overall I do recommend Promasil in the right situation. A 7 for a high priced prop blend that worked well for me. I think that's fair.

Let's get down to business. I've tried several other protien based powder which contain similar forms of whey protein isolate, but this is by far the best. The stevia sweetening is genius and I can't remember undermixing it bceause I don't think you can! Just remember, get the milk chocolate. The other flavors just aren't as good.

If you want a low calorie post workout product that is going to get those aminos to where they need to be (your muscles) I'd recommend you try this stuff

Top dog on the market. I have been using protein powders for years and it's official, Rivalus has done it! This protein is great for a weekend warrior or a professional athlete. I use it twice a day and after going through 2 of the 4.66lb buckets I have yet to get an upset stomach or come across that chalky taste that is inevitable with most proteins. I am sold on this product for good and would recommend it to my family and friends.
