Depends on how your going to run your epi cycle. I ran mine as a pulsing cycle. Ran it as follows:
week 1: 10 mgs (1 capsule) every other day
week 2: 20 mgs (2 capsules) every other day
weeks 3+4: off
week 5: 20 mgs (2 capsules) every other day
week 6: 30 mgs (3 capsules) every other day
week 7+8: off
week 9: 30 mgs (3 capsules) every other day
week 10: 30 mgs (3 capsules) every other day
weeks 11+12: off
week 13: 30 mgs ( 3 capsules) every other day
week 14: 40 mgs (4 capsules) every other day
On cycle I took multivitamin, cycle support, EFA's, and axis labs smash (creatine + N20). As PCT I took post cycle support (contains reversitol), diesle test hardcore, axis labs smash, multivitamin, and EFAs. Running the pulsing cycle I had pretty much zero suppression and I had my vitals run afterwards and everything was spot on. Its always good to have a SERM but running my pulse cycle I didnt need one. Everyone is different though so id start with a low dosage of epi and work up from there to see how your body responds. Good luck with the cycle though and keep us updated!
