I don't know about pure DHT-powder, but Masteron, Primobolan and/or Proviron can keep your E2 in check depending on the dose. A 2:1-1:1 ratio of testosteron to Masteron/Primobolan will probably be sufficient.Oh interesting. I guess the same might also be true of using pure DHT for AI then?
However, it can vary depending on the individual. Typically, Masteron is more potent than Primobolan in that regards, but they can all come with other unwanted side-effects.
