Swedish Supplements has for a long time gathered scientific knowledge about the synergic effects of ingredients and how to create products with a substantial impact and how to make maximum use of the biochemical mechanisms available. After years of development, the Butcher is finally here. A heavily dosed pre-workout product with popular ingredients in carefully thought-out compounds to give you the little extra that can lift your results in the gym. The mix of L-Citrulline, L-AAKG, buffering salts, creatine and beta-alanine provides greatly increased blood flow to the muscles, a powerful pump as well as an increased explosiveness and lactic acid resistance. Caffeine, herbal extracts, and amino acids contribute to a razor sharpness and a focus through the pass without any sense of crash afterwards. The palpable energy boost comes from the synergy between caffeine, Glucorolactone and the amino acids Taurine and Tyrosine.
