Myprotein Instant oats unflavoured is the seller by nothing but pure oatmeal (which for me is a positive criticism).
It is very finely ground and therefore readily soluble in shakes. For taste, as already mentioned by the Vorrezensenten, there is nothing negative to say, it is just oats.
My standard shake with the Instant Oats consists of oatmeal 150g, 30g protein powder, 500ml milk. The everything dissolves easily in the hand shaker and tastes thanks protein powder also delicious, in my case of strawberries ...
So a shake has approximately 930 kcal, as you have enough energy to get in top shape through the morning and due to the high fiber content of oats you're a long time saturated and may well survive without snacks until lunch.
Lately, I have made myself now and then also a "Sport Pizza":
For this I take 250g instant oats, 200g low-fat quark, only 15ml of water, 1 tablespoon olive oil and half a packet (ie ca.3,5g) Trockenbackhefe. This will be kneaded well and rest after 2 hours, you have a great pizza dough.
Just try it;)
What I'm saying is actually, you can use the Instant Oats versatile, which is also a reason why the pure flour variant (unflavoured) is for me the most sense. Pizza dough with for example vanilla flavor is then but not really my thing ...
So; Long story short:
Definitely worth the money in my view, I actually have no negative criticism!
Another little tip:
The resealing of the bag works well, but not rashly throw your old Proteinpulver- / Weight Gain punch box away, because it is of course a bit cumbersome if you look must bring every small portion of a 5kg bag ...
