I love the OPMS brand, they always have great products from there silver line to there Gold. The shots are great because the potency is so high, one bottle is 8.8ml, and on a normal day I’ll take 1ml mix it with a little water in the empty bottle & it can last a couple hours. It helps keep my tolerance low while still enjoying the potency of it, & it’s a good way to dose throughout the day if you want.
