OSTAR1NE converts to E2 so you will notice things like that if you are estrogen / gyno sensitive. I normally notice about 2 weeks in on an effective dose. However the E2 is also part of what helps you heal while using Osta. So crushing all of it won't get you healing effects if that is what you are after.

Maserati Wife, I would pick up either TransFORM, or AR1MACARE Pro. Ar1macare Pro is an all in one cycle support that has arimistane in it as an AI. It is effective in controlling estro and also for controlling cortisol. Also has TUDCA and some other important supports in there. The anti-cort properties of arimistane make it great during PCT because it controls the normal cortisol spike that starts about 1.5 weeks into PCT which is when most people lose that hard earned muscle from the cycle.
If using OSTAR1NE for it's healing properties I would opt for TransFORM, this way you do not lower cortisol to the point that inflammation gets out of control. YOu need the cortisol in enough amounts to do it's job if healing is your goal. If so I would use TransFORM and only use enough to keep any feeling of gyno at bay but do not use it to try to get the dry look. If healing is the goal you want to have some E2 in your system. Don't be so vane you don't get to experience the healing because you chose to go after temporary aesthetics.
These are just my opinions on the matter from what I have both read and experienced with the compound.
