STIM FX - the new pre workout from Optimum Health Supplements!

Following on from UNLEASH HELL V3 we wanted to tone things down slightly. Our new Stim FX is a blend of clean stims and high-quality Nootropics.  We wanted lots of clean energy and insane focus to power you through the toughest/longest workouts. The feedback on our trials has been fantastic, the number 1 comment was “lazer like focus” followed by “I felt like I could just keep going and going”. You will not be disappointed.

Our new formula consists of:

3200mg of BETA ALANINE which enhances performance by increasing exercise capacity and decreasing muscle fatigue.

2000mg of N-ACEYTL L-TRYOSINE greatly improves alertness, attention and focus

1000mg of L-TAURINE helps improve energy levels, combat exercise-related fatigue and reduce muscle damage.

500mg of CHOLINE BITARTRATE known to increase cognition and brain function, improve focus and motivation, and reduce fatigue.

300mg CAFFEINE ANYDROUS a nervous system stimulant that clears drowsiness and gives you an energy boost to stimulate athletic performance or weight loss.

200mg INNOSLIM® Increases glucose uptake in skeletal muscle cells, increasing fatty acid breakdown in fat cells, increases AMPK activation in skeletal muscle

150mg GUARANA SEED EXTRACT rich in caffeine, which can reduce fatigue and improve focus. Caffeine blocks the effects of adenosine, a compound that makes you feel drowsy and helps your brain relax.

100mg COCOABUTEROL® supports physiological pathways which improve insulin sensitivity, supports muscle protein synthesis, decreases skeletal muscle atrophy, promotes fat burning, increases blood flow, enhances mood and has antioxidant effects.

50mg L-THEANINE enhancing attention & focus. Under stress, the body increases the production of certain hormones, including cortisol and corticosterone. L-theanine helps to lower levels of the stress hormone corticosterone.

5mg BLACK PEPPER EXTRACT (st. to 95% Piperine) used increases the absorption of compounds.

20mg NIACIN (vitamin B3) used by the body to turn food into energy. It helps keep your nervous system, digestive system and skin healthy

1.4mg VITAMIN B6 (Pyridoxine HCL) is important for normal brain development and for keeping the nervous system and immune system healthy.

1.4mg VITAMIN B1 (Thiamine) helps the cells in the body convert food into energy.

Awesome pre workout! Great balance between super stimulant and laser focus at an incredible price! Makes waking up at 0430 to train a hell of a lot easier

First time buyer

As a first time buyer new to OHS, I contacted Pete regarding some products available. I found him very helpful & placed my first order of Whey & pre w/o. The products arrived less than 48h later and I can honestly say the whey is a cut above anything previously purchased. Pre is pre - never tasted one yet that doesn’t make my eyes tingle but this certainly adds focus and drive. Excellent all round.

Lauren Barratt
