I recently did a 2 week cycle of M1T and gained 7lbs using 10mg/day. I already had some nolva (pill form) on hand for PCT, although I have had it for about 1 year. I have been taking the nolva for 10 days now, 4 days at 40mg and 6 days at 10mg. So far I have already lost 5lbs, which is almost all of my gains from my cycle. Training and diet have been on track, so is it possible that this is due to my year old nolva? Could it have lost its effectiveness for PCT?
