excellent products, eeas and amino acids definitely help with recovery, pre work out gives a good kick. for me the taste is a bit too sweet for all these products. ideally i wish we had unflavored versions.

The sample box is nice. The 4 different powders all have a lot of serving in them. Some don't mix that well with the instructed amount of water, but a little bit more water makes it mix better. Beware of the size of the scooper for the pre-workout. You only need 1 scoop, and not 3 like it says in the instructions. Overall, I like these powders and they work pretty well.
Goes Well With:
Water.

Got the Item as an add-on. Pretty stoked to try a variety of Pro Items. Flavors are great. Only one issue is that I’m pretty sure the scoop for the Pre Workout is wrong. The Serving Size 3 scoops (15g) but the included scooper measures 18cc (so if 1 cc = 1g, then 3 scoops = 54g!) Be on the lookout since preworkout can give you jitters if you take too much. Glad I opened the other samples first since those have much smaller scoops. 

I was lucky enough to get this pro sample box and am very happy. The shaker is super nice, stainless steel with a variety of samples to choose from. I will be purchasing two of the samples in larger volume now that i had the chance to taste these. I would recommend picking this up!

Let me start by saying I have used many (at least 10) different pre-workout powders with caffeine and I have been fine. However, using the pre-workout sample from this box (I followed the label - Serving Size 3 Scoops) and it did not mix well at all with 12oz of water. It was extremely sweet and chalky and there was still powder left at the bottom after a full minute of shaking (this is way more time than I usually spend). I was absolutely wired during my workout (kinda nice actually) but shortly afterwards I had a very runny bowel movement and the bowl was BLUE (flavor was blue raspberry). That's when I knew the serving size is definitely incorrect, DO NOT TAKE 3 SCOOPS! I had 3 more bowel movements the same day, all runny and blue. Suffice it to say I am miserable, and this has never happened even with other preworkouts that have more caffeine (250+ mg) per serving.
Goes Well With:
ONE SCOOP, not THREE

A perfect way to get started with My-Protein to get to know their products. All of which are great!

This is a great option when bought on sale to taste different products plus a shaker. Will definitely be buying the coffee boost separately. 
Goes Well With:
Almond milk or water 

1st review here. I love Myprotein products. Great stuff, variety, and deals. I was dssapointed (at myself too) for the pre workout directions. It says 3 scoops per serving for a total of 10 servings. First time I tried it it seemed like it was too much, but I was dumb to disregard it. Right after taking it I felt weak, and my stomach reminded me in the next few hrs of how much I took. The directions pretty much tripled what it should be, so be careful.

Since I tried my protein products I loved, the best flavor and the best quality for all product, I used and recommend for everyone.
