IBCAA 4:1:1

IBCAA 4:1:1 is a great branched chain amino acid mix that many people will benefit from. The 4:1:1 ratio means it does contain more leucine than the 2:1:1 formula. Leucine has been shown more recently to increase protein synthesis and therefore the 4:1:1 comes highly recommended. We stock 1kg packs and discounts start at 2.9% for a 2 pack and go up to 18.6% for a 15 pack.

IBCAA 411 provides a 4:1:1 ratio of Instant Branched Chain Amino Acids, that contains four parts leucine to isoleucine and valine.

Our Pharmaceutical Grade BCAA's are completely water soluble and mix easily with a spoon. They also taste fine as they have one tenth the bitterness of regular BCAA's.

Recent studies show that Leucine is the main BCAA which activates anabolic signalling that occurs via the mammalian target of rapamycin (mTOR) which is responsible for muscle anabolism.

As a result leucine has become the primary BCAA responsible for promoting protein synthesis to enable recovery, muscle building and fat loss. Therefore we have provided an alternative to the traditional 2:1:1 ratio of standard BCAA's at a cheaper price.

Studies have shown that leucine and BCAA's may assist with:

  • Increasing strength performance, (Ispoglou et al, 2011)
  • Muscle recovery & immune regulation for sports events (Negro  et al, 2008)
  • Increasing resistance to fatigue, (Gualano et al, 2011)
  • Increasing endurance exercise capacity (Masumoto et al, 2009)
  • Increases in fat loss (Layman et al, 2003)

Ingredients: Pharmaceutical Grade Instant Branched Chain Amino Acids, 0.8% Sunflower Lecithin

    Serving Size

    Posted by on 26 May 2016

    I'd like someone to explain to me how the recommended serving size of 1 heaped teaspoon can weigh 5 grams. I used a digital scale and a single teaspoon doesn't even register! I order to get 5 grams, I need to use a heaped TABLESPOON!

    I am new to taking bcaa's and was naturally skeptical of their usefulness if one were taking adequate amounts of protein. Indeed, a quick trawling of the literature and body building message boards online will give a veritable smorgasbord of opions ranging from seemingly plausible to downright bro science. And so the only way to really know the truth of something is to try it for your damn self.
    And so try I did. And notice a BIG difference I also did. I went from using only protein to taking bcaa's pre and post workout and also before bed. After adding this to my routine I noticed much faster recovery and ability to go much harder the next day. I can only assume that having an instant source of the 3 most utilised amino acids in muscle building available dramatically enhances repair and recovery. I'm going to keep using bcaa's as long as I'm training.
    Let the gains begin!!

    First time user

    I'm a hard gainer and have gained quite a few kilos through a meal program and found it hard to see any muscle tone/ build until I started using this product. My muscle definition is much more visible and as I'm not a fan of pre workout with caffeine and what not, having this pre-workout has allowed me to push through and endure my workouts.

    Excellent product, fantastic price.

    Posted by on 22 Jul 2015

    I recently did a month of intermittent fasting (approx 12 hours a day), I took this stacked in with MPI Casein in the mornings before fasting and again in the evenings post fasting with electrolytes and plain WPC. I maintained muscle mass during this period and lost fat, I noticed my delts in particular more defined.

    The taste is a little bitter, but who in the iron game doesn't put up with some discomfort for the bigger picture?

    Excellent value IBCAA.

    Look no further than PW's IBCAA's for your post workout needs.

    I really didn't know what I was missing out on until I added PW's BCAA's to my supplement list. This product allows me to make the most of my diet and maximizes my protein synthesis so I'm getting more out of what I'm putting in.

    PW's BCAA's mix easily, are neutral in taste (a big deal) and deliver proven results. Quite frankly you're cutting corners without it.

    Use with Glutamine and Creatine for excellent results.

    A different kind of horrible.

    Posted by on 12 Apr 2014

    Make no mistake - the BCAAs taste horrible. I mix them with Professional Whey's
    L-Carnitine L-Tartrate (another outstanding product) to make ...well ...a different kind of horrible. But let's be clear - it works. My recovery has definitely improved!

    Just right

    Posted by on 20 Feb 2014

    I take 1tsp unflavoured IBCCA per litre during my workouts and it couldn't be better. I use it to aid in recovery. Drinking it unflavoured is fine, just don't expected it to taste like a tropical party in your mouth. I drink it plain or add a little orange stevia flavouring if i feel like it.

    The perfect alternative to whey protein

    Posted by on 05 Feb 2014

    Professional Whey has improved the taste and dissolvability of their BCAAs since my last purchase. In comparison to other BCAAs on the market I have found this is a better quality, cheaper and less bitter product. I mix 5 g of BCAAs with 300 mL of water before and after my workouts, before bedtime and first thing in the morning.

    Easy to use

    Another outstanding value-for-money product from Professional Whey

    Posted by on 26 Dec 2013

    Excellent value BCAA's. Professional Whey's IBCAA is not only cheaper than other brands, its a better quality product. I won't buy anything else - A+ (I combine with Arginine AAKG and its a great pre-workout mix). Tastes nasty but so do all quality, pure BCAA's - add a little lemon juice if you can't handle the taste (you do get used to it however). Thanks Professional Whey!

    Tastes fine and mixes well

    Posted by on 19 Sep 2013

    I was a bit aprehensive about trying this. But add a bit of lemon juice and a pinch of stevia and it is like lemonade. It even tastes fine on its own. Best value product by far. Thanks PW!

    Pure, great value

    Posted by on 01 Aug 2013

    Dissolves easily. Tastes like any other pure branch chain, ie like crap, but that's what the pure BCAAs taste like, no way around it. Any flavouring or sweetener and it would not be the pure product! Easy enough to add some dextrose on your own to mask the flavour.

    Throw a pinch of this in to your Post WO to aid recovery.

    1/2 tsp in a drink bottle full of water, sip away at it intra-workout will help your muscular endurance across sets or through a
    functional fitness workout. (it will also make your drink bottle smell bad within a week or two. Wash it out regularly!)
