Magnum Hard Muscle Builder


– Builds More Muscle*
– Increases Energy*
– Decreases Stress and Anxiety* 
– Enables Quicker Recovery*



 Bigger, harder, leaner, more muscular, better energy, higher testosterone, less stress and anxiety, quicker recovery!  Finally a nutritional supplement, backed by science, which delivers the physique results you’ve sought after. 

When HARD MUSCLE BUILDER™ is combined with high intensity weight training your gains will be quicker and more consistent than ever before.  Even better, taking HARD MUSCLE BUILDER™ on a low calorie diet, as used to prepare for a physique show or photo shoot, you’ll retain more muscle throughout your diet and be a bigger, leaner, more densely muscled athlete.  If that wasn’t enough a key ingredient in HARD MUSCLE BUILDER™ was shown to increase strength, size, and produce a greater decrease in body fat over a placebo group. 

HARD MUSCLE BUILDER™ also boosts your immune system, increases your testosterone levels, combats stress, and lowers the muscle-cannibalizing hormone Cortisol.  Now you can stay natural while achieving the lean muscular body you’ve always dreamt of having. 



myHMB® helps prevent muscle wasting and protein breakdown, improves exercise performance, and reduces recovery time. Studies have shown HMB has a nitrogen sparing effect, slows blood lactate accumulation resulting in greater time to reach VO2 max, improves aerobic capacity, and aids fat loss from exercise.

In one human study using a 1.5-gram daily dose of HMB versus a placebo, the HMB group showed decreased muscle damage and protein degradation, a 13% increase in total weight lifted, and a 1.8lb gain in lean body mass versus a placebo in only three weeks! 

HMB has been shown to affect muscle protein turnover by stimulating protein synthesis via the mTor pathway, and by decreasing catabolic signalling pathways. HMB may also stimulate protein synthesis through the growth hormone/IGF-1 axis.


PureKIC® (Alpha-ketoisocaproate Calcium) is a keto acid of the amino acid leucine.  KIC is anti-catabolic, which means muscle growth by moving the body from a catabolic (muscle wasting) to anabolic (muscle building) state.  Studies have shown that KIC increases muscle protein synthesis, antioxidant action, improves nitrogen balance, fat loss, HMB synthesis, insulin release, anticatabolic action, ammonia scavenging and immune system stimulation.  Researchers demonstrated significant reductions in signs and symptoms of exercise-induced muscle damage following eccentric exercise when they gave their subjects a combination of HMB and KIC daily for 14 days.



KSM-66® is a standardized extract of the adaptogen Ashwagandha.  KSM-66® produced significantly greater increases in muscle strength and size over placebo groups, and significantly greater reductions of exercise-induced muscle damage. The KSM-66® group experienced a significantly greater increase in muscle strength on bench-press (26.4 kg for placebo versus 46.0 kg for KSM-66®) and leg-extension (9.8 kg for placebo versus 14.5 kg for KSM-66®). The KSM-66® group also showed a significantly greater arm muscle size increase (5.3 cm2 for placebo versus 8.6 cm2 for KSM-66®) and chest (1.4 cm for placebo versus 3.3 cm for KSM-66®).  The KSM-66® group also demonstrated a significantly greater reduction of exercise-induced muscle damage, a significantly greater increase in testosterone levels (+15%), and significantly greater decrease in body fat percentage when compared with the placebo group.


Bigger, harder, leaner, more muscular, better energy, higher testosterone, less stress and anxiety, quicker recovery! Finally, a nutritional supplement, backed by science, that delivers the physique results you’ve been looking for!

How quickly can I expect results from Magnum HARD MUSCLE BUILDER™?
Reported results include strength, endurance, and recovery increases from the very first dose. Lean muscular gains, by their very nature, take longer, but users generally notice some lean gains within the first month of use.

What results can I expect from taking Magnum HARD MUSCLE BUILDER™?
Users routinely report an increased number of completed reps with weights than they normally train with. Users also report better recovery post training, strength gains, and more lean muscle. Each user will experience their own results, but all users report better results when pushing their limits to the edge while training. Hard Muscle Builder™ works best when you go harder than you normally would!

Will I get anxiety and/or jitters from Magnum HARD MUSCLE BUILDER™?
No. Magnum Hard Muscle Builder™ contains no stimulants of any kind. This makes it perfect for high intensity late-night training sessions or for stacking with Magnum PRE-FO®, our delicious, high-stimulant pre-workout!

What is the optimal way to take Magnum HARD MUSCLE BUILDER™?
We recommend that you take 1 capsule in the morning, 1 capsule prior to training, and 1 capsule immediately after working out. On non-training days take 3 capsules spread throughout the day. Combining with pre-workouts like PRE-FO®, or other supplements before you train is acceptable, as these will not slow down the absorption of Hard Muscle Builder™.

Are there any products you recommend to take with Magnum HARD MUSCLE BUILDER™?
Yes, Magnum HARD MUSCLE BUILDER™ has been formulated to work synergistically with Magnum OPUS®, DNA®, VOLUME®, PRE-FO® & THRUST®. Many clients have written testimonials on how these products helped them to set new personal strength records and drastically change their physique. However, Magnum HARD MUSCLE BUILDER™ can be stacked with any of Magnum’s products for your own unique stack. *
