  • Peri-RX new formulation

    Not sure if this was covered elsewhere. Can you explain a bit about the reformulation of the new Peri-RX? I believe I have this info correct off the supplement section of the site...

    Old Peri-RX
    8 grams of muscle-building Branched Chain Amino Acids (BCAA’s) in a 2:1:1 ratio (Leucine:Isoleucine:Valine)
    2.5 grams of Creatine Monohydrate
    3.2 grams beta alanine for increased work capacity and volume tolerance
    4 grams of Citrulline Malate to enhance muscle protein synthesis
    1.5 grams of HMB for improved recovery
    1000mg of Betaine Anhydrous to complement creatine’s effect on increasing cellular hydration and ultimately, may benefit performance and recovery
    800mg sodium to maintain electrolyte balance


    New Peri-RX
    10 grams of muscle-building Essential Amino Acids (EAA’s)
    2.5 grams of Creatine Monohydrate
    3.2 grams beta alanine for increased work capacity and volume tolerance
    4 grams of Citrulline Malate to enhance muscle protein synthesis
    1000mg of Betaine Anhydrous to complement creatine’s effect on increasing cellular hydration and ultimately, may benefit performance and recovery
    500mg Nitrate
    300mg sodium to maintain electrolyte balance

    And if it isn't too much trouble, I'm very curious as to how much Leucine:Isoleucine:Valine is in the 10 grams of EAA's. I'm a bit hazy as to the optimal dose for them.

    I'm assuming these are the EAA's:
    Tryptophan
    Valine
    Threonine
    Isoleucine
    Leucine
    Lysine
    Phenylalanine
    Methionine

        Not sure about Jordan's reasoning but pretty sure HMB turned out to be not as advertised by the earlier studies and nitrate has had some positive ones recently.

        The Stronger by Science had a segment on nitrate supplementing a while back that would probably be better at explaining it rather then my half remembered info on it.

          Why would this question be moved to the unmoderated forum? This is a specific question about a product sold by BBM?

            I am looking at the "new" Peri-Rx Watermelon as I type.... and I see NO Betaine Anhydrous. Also, nothing about anything "nitrate".

            Unless it's a label error, or unless "Beet Root Powder" means something special: both the BA and the Calcium HMB Monohydrate were dropped out.

            It's interesting to see (or infer) now that the key ingredients would be just four: the BCAA-EAAs, creatine, Citrulline Malate and Beta Alanine.

            As to the BCAA balance included in the new EAAs: um, RTFL - and do some grade-school arithmetic.

            The label states L-Leucine 3000mg, L-Valine 1000mg, L-Isoleucine 1500mg. So the ratio is 3:1:1.5, for a total of 5.5g of BCAA, along with another 4.5g of the remaining non-BCAA essentials.

            Lastly, my two cents on the sodium. It seems like a mistake for this product to include it. Most people's diets have more sodium than is good for them. I don't need more sodium, I need more potassium. As it is, I have to eat bananas to stave off spontaneous (resting) muscle cramps. At least the "new" formula adds a bit less sodium.
