During all my 25 years in this bodybuilding world i take alot of brands and labs , some very good yes mostly on past but alot of them very bad quality . Since i start using Med Tech i never stop because i always go for blood test every cycle and i know MTS is 100% real high quality. Ofcourse we have pharma grade that are top yes , but MTS gives you the same quality but much cheaper . Best relation quality / price
