Naposim are 5mg human grade methandrostrenolone made by Terapia in Romania. They have an excellent reputation as a properly dosed and high quality dbol among BBers. They are on par with the best dbols available on the market today, including Jelfa's Metanabol. Sadly, due to their popularity, they are counterfeited more often.
Here we have some pics of legit Naposim. Notice the 'nipples' on the plastic above the tablets and that the epiration dates/lot numbers are stamped on both ends of the blister pack, ensuring these dbols are legit.
