  • Can I stack Mr. Hyde® Test Surge?

    Absolutely! Mr. Hyde® Test Surge and Dr. Jekyll® were designed to perform individually and even better as a stack! By combining both, you harness the power of extreme energy and focus with enhanced pumps and training capacity and of course, the added Test-Boosting package. Additionally, Mr. Hyde® Test Surge can be stacked with other ProSupps products including Dr. Jekyll® PUMP Liquid Shots for a massive pump. We recommend assessing your tolerance if you decide to stack the two products by starting with ½ a scoop of each before proceeding to a full serving. †

  • IS MR. HYDE® Test Surge GLUTEN FREE?

    Yes, Mr. Hyde® Test Surge is formulated without any gluten containing ingredients.

  • What is HydroBCAA® +ESSENTIALS

    HydroBCAA® +ESSENTIALS is a complete amino acid matrix formula that utilizes the power of 7g of a research based 2:1:1 ratio of branched chain amino acids (BCAAs), 3g of essential amino acids (EAAs) and an electrolyte matrix to deliver comprehensive support to muscle tissue and promote exercise recovery, all in a sugar-free formula. †

  • What are the benefits of using HydroBCAA® +ESSENTIALS

    HydroBCAA® +ESSENTIALS contains both BCAAs and EAAs, a crucial aspect of formulation that helps ensure you are maximizing protein synthesis (for muscle growth and repair), supporting lean muscle, improving glucose uptake and effectively utilizing insulin, and supporting post-workout recovery. HydroBCAA® +ESSENTIALS also includes valuable electrolytes to help improve and maintain hydration both during and after exercise.†

  • What makes HydroBCAA® +ESSENTIALS unique?

    HydroBCAA® +ESSENTIALS is a revolutionary product as it not only features BCAAs (Branched Chain Amino Acids) but a comprehensive EAA (Essential Amino Acid) profile. This is crucial as recent studies suggest that consuming supplements with both BCAAs and EAAs has proven extremely effective at improving muscle protein synthesis. EAAs (including BCAAs) must be consumed from your diet or supplementation and when creating proteins in the body, including the protein that makes up lean muscle, all 9 must be present... not just the 3 BCAAs. As a result, without EAAs, the body will not build new muscle protein due to the lack of materials or worse yet, the body will start to break down existing muscle protein in order to get the required amino acids. In addition to the premium BCAA and EEA matrix, HydroBCAA® +ESSENTIALS features a unique blend of electrolytes designed to keep you hydrated through your workout and improve your overall recovery.†

  • What is the difference between HydroBCAA® Signature, HydroBCAA® +ESSENTIALS, and HydroBCAA® +ENERGY?

    The entire HydroBCAA® line is vegan friendly, zero sugar, zero carbs, zero calories, Banned Substance Tested and designed using our premium flavor system. The main differences between the three are:

    • HydroBCAA® Signature: 7g of BCAAs + 246mg Electrolytes.
    • HydroBCAA® +ESSENTIALS: 7g of BCAAs + 3g EAAs + 100mg Electrolytes.
    • HydroBCAA® +ENERGY: 7g of BCAAs + 125mg Caffeine + 160mg Electrolytes.
  • Why a 2:1:1 BCAA ratio?

    Numerous studies support the effectiveness of the Branched Chain Amino Acid ratio 2:1:1 for training for muscle size, strength, endurance and power. As the most studied BCAA combination, it has become the gold standard. And while other ratios exist, HydroBCAA® +ESSENTIALS has been formulated to include Essential Amino Acids and additional ingredients to further enhance the overall effect of muscle protein synthesis.†

  • Why 7G of BCAA?

    It has been demonstrated that 3.5g of Leucine is the ideal amount of leucine for maximizing muscle protein synthesis (repair and building of muscle tissue). Each full serving of HydroBCAA® +ESSENTIALS provides you with 7g of BCAA at a 2:1:1 ratio, meaning you are getting the research backed 3.5g of Leucine with the correct ratio of the other BCAAs in each serving for maximizing your results.†

  • When is the best time to use HydroBCAA® +ESSENTIALS?

    The ideal time to take HydroBCAA® +ESSENTIALS is anytime: before, during and after training. HydroBCAA® +ESSENTIALS helps support muscle tissue, stimulate protein synthesis and help reduce post-workout muscle fatigue among a variety of other researched benefits


    IncrediBULK® was created to be the most effective, highest quality lean muscle gaining formulations on the market. The fact of the matter is that some have faster metabolisms than others, and no matter how hard they try, they struggle to put on quality muscle mass. This is known as an ectomorph type body and can be one of the most frustrating issues when it comes to adding muscle size and weight. IncrediBULK® addresses the needs of the ectomorph ‘hard-gainer’ head on and pushes your lean mass building potential to the next level with a well-rounded profile featuring 250+ carbohydrates, 50g of premium protein and a total of 1,250 calories per serving. Further rounding out the nutritional profile is the addition of CLA and MCTs for lean muscle and metabolism support.


    IncrediBULK® is made specifically or those who have more of an ectomorphic or commonly referred to as “hardgainer” body type. These are individuals who have a hard time putting on lean quality muscle mass or weight and need the assistance of additional, high quality calories in order to grow and maintain weight.


    The protein sources utilized in IncrediBULK® include premium whey protein concentrate and milk protein isolate to deliver a fast, medium and slow digesting protein source for sustained amino acid levels.


    No, you may split up a full serving (3 scoops) of IncrediBULK® for a more customized approach to incorporating the quality calories it contains. Whether you simply need fewer calories than a full serving to help meet your goals or if you want to split up the full serving to separate times during the day, either way is perfectly fine!


    IncrediBULK® is best used first thing in the morning, between meals, or post workout. This is the time that your body is most responsive to a calorie influx and will best help to add and maintain lean, quality muscle mass.


    Yes, IncrediBULK® is formulated and manufactured free of gluten containing ingredients.
