So far so good 👍🏽

Early stages of use but it is very good so far. These sort of powders are sometimes very sickly and lumpy because only the thickening agents used. This is a light and tasty powder (vanilla). Because I'm new to using I'm not using the 3.5 scoops recommended (as that's only 10 portions) closer to 2 scoops either in milk or porridge and so far so good with no after effects or bloating. Recommended!

Long time user - great taste

Perfect taste I wouldn't use any other brand, worth the money

Very tasty, good quality protein powder

Banoffee is a great flavour for a protein shake, and you get a decent portion of it for what you pay. Can definitely recommend mixing it with full-fat or semi-skimmed milk as opposed to water though, especially if you want something filling if your next meal is a few hours away.

Only criticism I can have is that sometimes the scoop that comes with it sometimes finds its way deep into the powder, so you have to really go digging, which can be a bit of a faff. But if you keep the scoop after you're done, you can use it for future and avoid the problem with the next one.

Easy to mix with water, helps my body recover quicker

Beyond sickly sweet, sack the taste panel!!!

I used to ONLY drink maximuscle banana flavour. To my horror they no longer do just banana.

I love a bit of banoffee so gave this a go. Flavour is ok but OMG it's like they had a 10 year old do the tasting. It's beyond sweet and I've got a sweet tooth.

Quality as always is decent and maintains my muscle %

Packaging is annoying, bulky and often hard to get the last bit out without tipping it out and then missing.

Excellent product help improve muscle.

Taste is excellent and works very well.

Not a miracle worker, definitely plays its part!

Heavy training 4 times a week, good diet, good sleep, a couple of other supplements (LA Muscle and Creatine), 2 of these shakes a day supplementing with meals 5 days a week, 12st 1lb to 14st in 3 months.

Great strawberry flavoured shake (Genuinely reminds me of McDonald's). Absolutely plays its part and does what it's intended to do for me!

I never review things, but this deserves a review. Maximuscle provide the best protein supplements, fact. This tastes amazing, like a fresh strawberry ice cream, put some ice in your shaker it's amazing. I have used various brand and nothing compares to maximuscle. Stick to maximuscle and achieve your goals, don't believe in the fake paid influencer hype of other brands.
