Effects on training:
I ran out of whey powder before I bought this tub on Amazon. I have trained several periods in the last years with and without whey protein (replaced shakes with natural protein sources). I personally like the quick absorption of Optimum Nutrition Whey, the flexibility and creativity it adds to my day-to-day activities and the quality of the product. I have barely any other option to quickly get a protein amount while I am juggling my job, my workouts and my friends.
I personally think this whey protein has good effects on my training.
(I have gained about 10 lbs of muscle mass in the last 12 months of training - 4 day split). I run 2-3 times a week (approx. 30 minutes).
I have tried several brands before I discovered Optimum Nutrition. I prefer the Milk CHOCOLATE taste and it really does taste like chocolate. There are sweeteners in this whey but you can't really taste them.
Mixing with WATER:
Using a SMART SHAKER (tm) - mixes OK with water, there are no lumps and the process is quick. However the TASTE changes a bit if you are using the Milk CHOCOLATE with water only.
If you have further questions please do not hesitate to contact me.
Mixing with MILK (low-fat 0.3% milk):
Using a SMART SHAKER - mixes really well, taste is excellent. No lumps or issues. If you shake it hard enough there will be a little bit of "foam" on top of your shake which is good.
Mixing with fruit juice:
I have tried MINUTE MAID Orange Juice - mixing was no problem but I personally didn't like the chocolate/orange taste (but I also don't like this combination in chocolate, others love it - just try it out!)
Mixing/Combining with Quaker Oats (oatmeal/porridge):
ON Double Rich Chocolate with oatmeal adds a great chocolate taste and makes the oatmeal more appealing. However, there is also a floury side taste (similar to mixing with water alone) which is the only downside. I can live with it.
NEGATIVE / ADVERSE effects on body, skin or hair:
