I wanted to wait a bit before leaving a review and after two weeks of use, I think it's time.The product is really good. I've never used sustain supplements before during my workouts, so I wasn't sure what to expect. I've definitely felt a difference with it, it helps me to push my last few reps and squeeze out the needed energy to finish.The taste is alright, not the best but after a few uses, you get used to it.Quick disclaimer; a family member tried it as well and said they had a weird feeling in their stomach from it, I personally haven't had any problems with it, just be mindful your body might react differently to it.

By far the best tasting BCAA
Absolutely love the flavour and taste of this product. I have tried a few others and honestly they are normally overly sweet or terrible at mixing.The Optimum Nutrition strawberry kiwi mixes easily and tastes great! I would highly recommend

Tastes good,gentle on stomach, bit pricey
Great taste (raspberry and pomegranate flavour), not too sweet or artifical, really does taste of raspberries fresh from the field/packet! Nice inclusion of electolytes as well as the essential BCAAs, not sure the inclusion of vitamins worthwhile TBH though in a BCAA drink. Mixes well with water with no clumping. Would like to see the price a little lower, its a small tub (260g) yet almost the same price as Grenade BCAAs which come in a 390g tub and are much better value.
