|Citrulline Malate 2:1 | 8,000 mg|
From a performance standpoint, citrulline malate is the “star child” of pre-workout science.
We chose citrulline malate over L-arginine because it provides better absorption, higher plasma arginine levels, and has been found to:
PreSeries STIM-FREE contains 6,000 mg (6 grams) of citrulline malate per serving.
|Beta-Alanine | 4,000 mg|
A majority of pre-workout supplements contain beta-alanine, but at significantly underdosed levels. Supplementing with proper dosing, as found in PreSeries BULK, is shown to:
PreSeries STIM-FREE contains 4,000 mg (4 grams) of beta-alanine per serving.
|BetaPure™ Betaine Anhydrous | 2,500 mg|
Recent clinical studies suggest that betaine supplementation triggers a significant muscle growth response. This response is independent of testosterone and is significantly advantageous alongside typical supplementation protocols.
Betaine supplementation has also been shown to:
PreSeries STIM-FREE contains 2,500 mg of betaine anhydrous per serving.
|Taurine | 1,300 mg|
Taurine is an amino acid that is essential to pre-workout supplementation. Taurine competitively interacts with beta-alanine; thus, supplementation with beta-alanine and without taurine can lead to states of taurine deficiency .
Additionally, taurine used alongside BCAAs, has been found to reduce next-day muscle soreness more than either taken independently .
PreSeries STIM-FREE contains 1,300 mg (1.3 grams) of Taurine per serving.
|L-Tyrosine | 1,000 mg|
L-tyrosine is the acetylated version of the amino acid L-tyrosine. The acetylation improves the absorption and effective period of L-tyrosine, as well as optimizes the effectiveness of the energy and focus ingredients in PreSeries STIM-FREE.
PreSeries STIM-FREE contains 1000 mg of L-tyrosine per serving.
SenActiv® is a patented combination of two adaptogenic extracts: Panax notoginseng root and the more familiar rose hips (Rosa roxburghii). The notoginseng in SenActiv is highly concentrated in notoginsenoside R1, a beneficial compound that helps accelerate muscle recovery during/after intense exercise. Likewise, the rose hips provide several ginsenoside-like molecules that confer synergistic recovery-enhancing effects with ginsenoside R1 .
The distinguished adaptogens in SenActiv are suggested to work by bolstering a cellular process known as autophagy, particularly in skeletal muscle cells [34, 35, 36]. This serves as a bona fide "cleansing" of damaged organelles and structures within cells, and those components can then be recycled to make new molecules essential to cellular homeostasis. Hence, the resultant cellular damage from intense exercise requires efficient autophagic coordination for optimal recovery, and that's precisely where SenActiv comes into play.
|elevATP® Ancient Peat and Apple Fruit Extract 150 mg | 150 mg|
|BioPerine® | 5 mg|
BioPerine® is a patented extract obtained from black pepper fruits (Piper nigrum) standardized minimum to 95% Piperine. BioPerine® may be co-administered with various nutrients to enhance their bioavailability in both human and animal. In general, BioPerine® was found to enhance absorption of nutrients by at least 30%.
PreSeries STIM-FREE contains 5 mg of BioPerine® per serving.
|Huperzine A | 100 mcg|
