Pre-workout stimulant Dr Jekyll Signature - an innovative caffeine-free pre-workout suitable even before evening training

Pre-workout stimulant Dr Jekyll Signature is characterised by a functional composition operating in 3 areas of sports performance. The performance-enhancing complex contains the amino acid beta-alanine, from which carnosine is synthesised together with histidine in the body. The higher concentration of carnosine in the muscles is associated with its ability to reduce muscle acidity during exercise and potentially improve performance. Other substances in the complex to increase performance during intensive training include creatine and inositol.


The second building block of the product is complex to improve concentration during training. The complex contains choline bitartrate, which is a precursor of acetylcholine, which plays an important role in the optimal functioning of cognitive abilities, concentration and muscle activity. It also contains tyrosine, which is the amino acid needed to make dopamine and adrenaline, and ginseng, which is an adaptogen.


The last adaptogenic complex consists of Ashwagandha extract (Withania Somnifera), which, like ginseng, can help to cope better with stressful situations and increase physical performance. Furthermore, aframomum (Aframomum Melegueta), which has similar bioactive effects as ginger. The last substance in the complex is black pepper, which increases the bioavailability of some substances.


Pre-workout stimulant Dr Jekyll Signature does not contain caffeine and is therefore particularly suitable for use in the late afternoon and evening without a negative effect on the optimal sleep regime, which can be disrupted by high caffeine consumption.


If you have your caffeine intake under control and its use does not cause you a problem even later in the day, you can combine the pre-workout stimulant Dr Jekyll Signature with caffeine stimulative substances.
