Pre-Workout PRO ST is a highest quality concentrated powder pre-workout with a perfectly balanced composition and scientifically proven* by the University of Greenwich that provides all the nutrients necessary to enhance your workouts and competitions, both strength and endurance .

Its extraordinary formula consists of:

  • Essential Aminoacids (EEAA): necessary and fundamental for the perfect functioning of the muscles that are working. Pre-training intake of these amino acids has been shown to delay fatigue and improve recovery through less muscle wasting (Jäger, R. et al., JISSN. 2017; Hoffman, J.R. al al., IJSNEM. 2009). Provided in optimal proportion, similar to that of muscle mass.
  • Nitric Oxide Precursors (NO)
  • Taurine: among others, it has antioxidant, metabolic and ergogenic effects (Galloway, S.D.R. et al., JAP. 2008). Its intake along with the other ingredients has been shown to improve muscular endurance during exercise (Hoffman, J.R. el al., JCSR. 2008).
  • Tyrosine
  • Betaine: This glycine derivative improves performance because, among other effects, it increases the rate of re-synthesis of creatine and increases the levels of nitric oxide (NO) in blood (Trepanowski, J.F. et al., JSCR. 2011). It also improves total volume loading to fatigue, in addition to improvements in power and force output (Lee, E.C. et al., JISSN. 2010).
  • Acetil-L-Carnitine
  • Caffeine and Yerba Mate: We have added (in pure form and as Yerba Mate) the most effective ingredient for direct performance improvement, both endurance and strength (Grgic, J. et al., BJSM. 2.019), caffeine. In addition to activating the Central Nervous System (CNS), it delays fatigue and optimizes the use of cellular fuels (glycogen and fat). But the most important thing is that it improves muscle contraction (Lopes, J.M. et al., JAP. 1983), hence its effectiveness especially when fatigue begins.

* Scientific study under revision. This matrix of ingredients was studied with 2 portions (30 g) of PRE Workout PRO ST together with about 16 g of added carbohydrates, so if you want to take a product similar to that of the scientific study, you can add 2/3 of the intake (approx. 20 g = 1 +1/2 of intake) from Isodrink & Energy Lemon and the effectiveness will be maximum according to the scientific study.
