A Blend of Quality Protein Rich Supplements

Hydro-ISO Performance uses top quality hydrolysed whey and whey isolate to formulate a purer protein rich supplements mix that supports top end muscle growth and recovery.

When to take this? FIRST THING IN THE MORNING & POST WORKOUT. Using top end post workout supplements makes this protein ideal to have first thing in the morning when the body has been depleted of nutrition overnight due to sleep. This Hydrolysed Whey Protein is also ideal to have as a post workout shake due to its richness in muscle growth supplements. If you did opt for this, we would also recommend combining with “Muscle intra xcel” (carb recovery product)  to replenish the body with carbohydrates post exercise. This protein also boasts 6.2g BCAA which is great to enhance muscle recovery. Finally, this protein has less than 1g of sugar and 1g of fat making it perfect for anyone with strict calorie intake like a dieting bodybuilder. Unlike in other post workout shakes, taste has not been compromised. In fact, it is our biggest seller for a reason.

    Great tasting protein that does exactly what you want a quality supplement to do, mixes great and no bloat which I’ve found when consuming some proteins pre and post training. Like most consumers that train I’ve tried a lot of different manufacturers and find fission hard to beat in terms of quality.

    Great taste. Love the salted caramel. Undeniable quality.

  4. Liam (verified owner)

    One of the best if not the best post workout proteins I’ve used thus far, mixes well tastes amazing zero bowl or digestion issues and the price compared to other hydrolized or whey isolates is atleast a £10 difference if not more if you use a promotional code which there usually is one on most of the time. LOOK NO FURTHER FOR A FAST DIGESTING RAPID ABSORPTION PROTEIN

    Great customer service and rapid delivery, along side a very responsive team on their Facebook page also.

    The best protein I’ve ever used! Salted caramel is my favourite. Tastes nice, doesn’t cause bloating and mixes well with water as a shake and perfect to cook with (pancakes being the best)! Most other brands trigger my IBS and causes my skin to flare up but I’ve never had any issues with Hydro Iso.

  6. Koh Ong (verified owner)

    Blends well with no clumps , great taste is a bonus ! Definitely see the difference in quality after only 2 weeks! Recovery was noticeably faster. (Was using On for a year)

  7. kevhodge2802 (verified owner)

    Quality product is the hydro iso whey love the salted caramel taste one of the best proteins I’ve had for taste and mixing.
    Very helpful people if got a problem fast response to questions.

    Used Hydro Iso for the last 2 years and not looked elsewhere since. Tastes great and mixes well, I have had the chocolate and vanilla and would recommend both. Previously used other brands (my protein/BSN) but found hydro iso was the best for taste and price on the market. In other brands I have struggled with the high lactose content in them, I have had no issues at all using hydro iso. Would highly recommend.

    Great value, taste and service. Been using Fission for awhile now and wouldn’t look back!

  10. Brian Owens (verified owner)

    Started using fission recently. Easy to mix, tastes great, and goes down well. Excellent product.

  11. Suzanne (verified owner)

    One of the best if not the best post workout protein I’ve tried.

    I’ve been using this product since late 2016, & my go to flavours are Chocolate & Strawberry. The protein is really smooth, blends well & it does not cause any issues with my IBS.

    I honestly wouldn’t ever change to any other brand again.

    Customer service has always been spot on.

    Been using this protein for a few months now an the taste & quality is amazing! Just what you look for in a protein!
    Great value for money & great service.

    I’ve Struggled with a sensitivity issue towards milk and whey proteins for several years, I’ve tried vegan options in the past but the general taste was a downside and I still suffered from bloating. I Cut out all shakes completely for at least the last 12 months until I was recommended hydro iso performance to which at first I was slightly sceptical as it still contains whey, however to my relief, I suffer no bloating no stomach cramps or side affects at all! Absolute game changer for me, and for anyone with a similar sensitivity issue!
