Best post-workout product
As always, the people at Reflex have put together a great product. This one is designed to ONLY be used post-workout. Best to see the info at Reflex for everything that is included in this product. The only sssues with the product are: (1) the fact that the taste takes a bit getting used to (2) the cost However: (1) after a few weeks of using the product, I do look forward to it. See my mixing advice below. (2) but considering the ingredients list...this product is actually fairly cost effective; to stretch it out a bit more... I sometimes only use 70 grams of product instead of the full 105 (and then supplement with some whey) Best way to mix?: Despite some reviews to the contrary, I find Reflex mixes perfectly...but I advise buying the Reflex shaker...as other products just don't compare. Before the workout, I put 400-500 ml of water into the shaker...add 2 scoops of product and some whey.. (or 3 scoops of product)... add a scoop of powdered milk... shake until dead smooth. I then put in about 5 ice cubes and put in the fridge. At the end of my workout... the ice cold chocolate shake is there to enjoy. I've found fruit only makes this product taste worse...milk or water in my opinion is best. Also best ice cold. This product (like all Reflex prodcuts in my opinion) does not cause me any stomach or gastric upset; and only makes me feel good.

Terrible flavour
I have used before and is good but this flavour was a huge mistake

its good quality protein but ….
Reflex is one of the best quality proteins you can get for this kind of money. The only thing that bothers me is the servings, 105g is one serving, the usual serving for most proteins is 30ish grams, ive weighed it out and its 3 and a half scoops meaning the tub does not last long. The flavour in chocolate is very rich, almost like a bitter dark chocolate, wont be for everyone

Quality Product
Taste seems to be the main criteria for rating whey based supplements, but to the serious trainer it should mean nothing. This is a high quality product and delivers - no, the taste isn't great, but you get used to it!

I was drawn to this product because it contains hydroslysate which a lot of websites recommended. I am now on my second tub
I bought this product after researching on the internet about protein supplements. I was drawn to this product because it contains hydroslysate which a lot of websites recommended. I am now on my second tub, I have started to notice diffferences. Obviously there is no magic supplement out there apart from "juice" that is going to get you ripped, you have to put the work in. This supplement has the right balance of protein, carbs and low on fat. On first tasting the shake I was slightly pissed because it tasted horrible but I've actually got quite fond of it. Plus if you are sticking to a strict healthy diet you welcome the rich taste of this shake after all that bland stuff. I do recommend it. It might only be early days for me to say but this product suits me down to a T.

Tastes Horrible and Makes you feel sick to drink
DO NOT GET THIS!!! The product tastes absolutely disgusting and is inedible, I have had a lot of different protein shakes over the years and know what should be right and what is not. This is hard to keep down and makes you feel sick, go elsewhere and save your money as they don't offer refunds (Hmmmm I wonder why that is???)

The ultimate post workout supplement for anyone!
I have tried at least 30 different protein shakes over the past 8 years and nothing beats this...Since using this product for the last 3 years it has become the only post workout protein supplement that I will use or recommend to anyone else. The chocolate flavour is my favourite and the taste is not amazing but that should never be the point when buying a high quality post workout shake that has the best ingredients profile you can find! Reflex is definitely one of the best supplement companies in the world and you can always trust their products to give you the results that you are looking for. I find that the serving suggestion is a little bit too much for me and by cutting it down to 2 scoops it mixes better and lasts a bit longer while still helping you recover much faster than normal. I really hope that they never change this product or even worse stop manufacturing it.

Number 1 post workout
Expensive for what it is but the best post workout on the market IMO. I’ve been using this on and off for prob 10 years and nothing compares. Tip: Don’t get the orange one it’s disgusting but the choc one tastes great.

Kann ich nicht empfehlen, da der Shake wirklich ekelhaft schmeckt. Und ich finde, es enthält auch zu viele Kohlenhydrate, aber das ist nur meine Meinung.

The product is awesome but the flavour not as per my request and bad taste.
