No pip ever with methanolone enethate and ive used 3 different brands in my days results are consistent with other real primo. I bought sciroxx primo ace inject and that had major pip with flu and big ass lump. I sent it back and he replaced with these. Karl good guy and i like this primo enethate. Going on 9 weeks i have a quality look more roundness. Didnt pack on mass but primo wont ever do that i stay ripped and don't diet hard.
