B vitamins should be taken with Tren to reduce prolactin levels, it also gives a boost to metabolism and energy. My question is, some people say B6, some say B12, some say B Complex. Imo B Complex sounds like the best, but when I looked up B Complex online, it says it's a water based solution... Would this mean that it would not be a good idea to mix it in the same syringe as Tren Ace and Test Prop seeing as they are Oil based? I have heard that many people do it and it lowers the pain, but is it possible that it causes some of the Test or Tren to crash and that is why it doesn't hurt as much?
