Proccor Pre-RX – Workout Enhancement for Focused Athletes

Proccor Pre-Rx 2.0

Proccor has upgraded their monster pre workout Pre-Rx and it’s the perfect prescription for your workout.

Pre workouts are like dress shirts. You can have a different one for every day of the week. Some days you’re really feeling a certain flavor and go in one direction, other times you’ll need a huge hit of energy just to get moving and pick a different one.

With the wide range of options available, sometimes it can be dizzying to figure out which one to go for. When you come to a crossroads like this, it’s time to reach into the cupboard and choose a pre workout that hits all the right notes when it comes to energy, focus, endurance, and pumps.

Pre-Rx 2.0 is the brand new pre workout from Proccor that is a massive upgrade from its predecessor and looks to deliver on ALL fronts. But will it land a spot on our Top 10 Pre Workouts list?

We’ll reveal the panel below, but first, make sure to check the best deal and sign up for PricePlow alerts:

Pre-Rx 2.0 Ingredients

Pre-Rx 2.0 contains a hefty 21g scoop made up of 13 fully dosed ingredients including goodies like Betaine, Creatine, and Beta Alanine. You can also see the exact amounts of all the other ingredients thanks to the completely open label:

  • CliniForm Performance Blend

    • Citrulline Malate (6g)

      Proccor Pre-Rx 2.0 Ingredients

      Pre-Rx is packed with clinical doses of just about everything you’d want in a pre workout.

      This is how you start of a performance blend, with a nice full dose of citrulline malate. This is a dual-headed monster when it comes to pumps and performance.

      Most associate it with being a superior arginine/nitric oxide (NO) booster, but that only scratches the surface.[1] Citrulline reduces fatigue and soreness while improving your overall training capacity.[2,3] This enables you to workout harder for longer periods of time, which ultimately leads to better gains.

    • Beta Alanine (3.2g)

      When looking to improve your endurance, strength, and sports performance, there’s no better place to turn to than Beta Alanine. Once ingested, it binds to histidine in muscle cells to form carnosine.[4]

      Carnosine buffers the accumulation of lactic acid in skeletal muscle which helps reduce the “burn” you feel when doing high volume training or endurance sports.

      Pre-Rx 2.0 contains the full clinical dose of 3.2g which will help you increase power output, strength, muscular growth, and most importantly endurance and stamina.[5,6,7]

    • Creatine MagnaPower (3g)

      Developed by Albion Nutrition, Creatine MagnaPower is a patented from a creatine also known as magnesium creatine chelate. Here, creatine monohydrate is chelate bonded to a magnesium salt to improve absorption and bioavailability in the body.[8]

      While the current research MCC isn’t any more effective than monohydrate, we support its inclusion due to the additional magnesium it contributes to the diet.[9] Most of us simply don’t get enough of this essential mineral in our diets. It’s one of the main reason ZMA works so well for a wide range of people.

    • BetaPower (2.5g)

      Proccor Shaker

      Given the massive scoop size of Pre-Rx 2.0, you’re going to need a BIG shaker to mix it properly.

      Another PP favorite is the power booster betaine. Pre-Rx 2.0 uses the patented BetaPower form of betaine anhydrous, which has also popped up in Carbon Recover and Kris Gethin’s Pre-Kaged.

      More people are seeing a solid reason for using betaine, as studies have repeatedly shown it to improve power, endurance, and muscle protein synthesis.[10,11,12]

      Additional research also shows betaine reduces muscle soreness[13] and potentially enhances the body’s production of creatine.[14] Like every other ingredient so far in Pre-Rx 2.0, we get the full clinical dose of 2.5g.

    • Taurine (2g)

      Taurine is a conditionally essential amino acid that’s stored predominantly in the brain, heart, and skeletal muscle of the body. It’s acts as a cell volumizer in the body, helping to pull additional water and nutrients into the muscle cells[15], which sets the stage for some pretty nice “water-based’” pumps.

      Additionally, taurine may improve mental focus since such a vast amount is stored in the brain.[16] We’ve noticed more and more pre workouts including this ingredient as of late and are beginning to think they’re on to something when using a strong dose like the one here.

    • HydroMax (1.5g)

      Our last performance enhancer, and another cell volumizer, is the patented high-yield glycerol known as HydroMax. Regular glycerol monostearate contains only 25% glycerol by weight whereas this form contains 65%.[17] Basically you get more of what you want (glycerol) and less of what you don’t (saturated fat).

      HydroMax turns your muscles into a super-absorbent sponge that sucks up extra water to store. This creates a state of “hyperhydration” that leads to increased endurance[18,19] and further fuels those water-based pumps we just mentioned.

      Make sure to drink plenty of water when using HydroMax pre workout (at least 16 oz of water) to get the most from this ingredient.

  • Focus, Pump, & Stim Blend

    • L-Tyrosine (1g)

      Proccor Stack

      Pre, Intra, and Post, Proccor has all of the bases covered.

      Tyrosine is a non-essential amino acid widely used to enhance focus during your workouts. It increases the production of dopamine and noradrenaline, two highly important neurotransmitters in the body. In addition to improving focus and overall cognition, tyrosine also helps reduce symptoms of stress and anxiety.[20,21]

    • VitaCholine (575mg)

      VitaCholine is a patented form of choline bitartrate manufactured by Balchem.[22] Most associate choline products with improving cognition, since it forms the backbone of the “learning transmitter” acetylcholine.[23] However, choline also imparts performance benefits for athletes.

      During intense physical activity or sporting event, choline levels become rapidly depleted which can lead to impaired performance.[24,25] Supplementing with choline prior to your workout or competition will bolster your choline reserves and enable you to continue to perform at your peak output.

    • PhenylThin (300mg)

      To boost your overall mood, Pre-Rx 2.0 contains PhenylThin, a patented form of Phenethylamine (PEA). This molecule functions as a neuromodulator in the central nervous system. It’s naturally found in nature, but more often it’s supplemented increasing levels of the “feel good” neurotransmitter dopamine.[26]

      The only drawback to PEA is that its effects last rather briefly, as it’s quickly broken down by your MAO enzymes.[27,28]

      Not much research has been performed on PEA in terms of enhancing exercise performance, but the increase in catecholamines should give you an extra boost in motivation to get in the gym.

    • PurCaf (250mg)

      L-Theanine Tea

      L-Theanine comes from tea leaves, and can helps smooth out some of caffeine’s more jarring stimulant kick.

      PurCaf is a patented form of caffeine that’s 90% organic pure caffeine extract derived from water-extracted green coffee beans.[29]

      Natural caffeine confers all the same energy-boosting and performance-enhancing qualities that more conventional synthetic forms of the stim offer. However, should you be a non-GMO fanatic, you can sleep sound at night knowing your caffeine source it’s naturally sourced.

    • L-Theanine (75mg)

      L-theanine has become increasingly popular in pre workouts to smooth out the harsh kick from high doses of caffeine and other stimulants, that some users experience. However, theanine does much more than that…

      It also enhances the cognitive effects of caffeine,thereby improving focus,[30] and helps reduce fatigue, stress, and anxiety.[31,32]

      Typically, we find a 3:1 caffeine:theanine ratio to be the sweet spot, and Pre-Rx 2.0 hits it right on the money.

    • Synephrine HCl (50mg)

      Synephrine is a naturally occurring alkaloid found in the Citrus Aurantium plant. It’s a potent Beta-2 and Beta-3 adrenergic receptor agonist[33,34] that liberates stored triglycerides and releases them into the bloodstream, a process known as “lipolysis”. This enables your body to essentially “burn fat” for fuel and save your glycogen stores for high intense activities.

    • Huperzine A (50mcg)

      While choline supplements help to directly increase production of acetylcholine, Huperzine A indirectly increases it. This molecule inhibits acetylcholinesterase, the enzyme responsible for the breakdown the acetylcholine.[35] Negating the effects of acetylcholinesterase means more acetylcholine is available which ultimately leads to better focus.

      Another interesting tidbit about huperzine, is that it protects against the “neuron death molecule” glutamine,[36] and possibly help create new brain cells thereby making it “neurogenerative.”[37]

    • BioPerine (6mg)

      With such a hefty scoop size chock full of ingredients, your body’s going to need some help absorbing each and every gram of performance enhancing goodness. Pre-Rx 2.0 contains the patented black pepper extract BioPerine to improve the bioavailability and absorption of all the other compounds.
