got some testabol propionate of a mate 100 mg/ml made by British dragon, he has been getting it of the same guy for a couple of years, he swears by the stuff and has had great results of it, i checked the hologram number with the website and its all legit, the reason im posting is because it was manafactured in 05/2001 and expires 08/ 2016......does gear really last that long?? 15 years!! im sure its fine but its worrying to think this was manufactured 11 years ago lol, will it get weaker over time does anyone know?
