Keeping Gains: the most important thing for keeping gains in PCT is to keep on the diet and training and try not to get demotivated when you see strength dry up. You WILL lose strength when you come off of SD and you WILL lose weight. If you don't lose any weight at all, you can be sure that you're holding a lot of water or adding fat. Keep the training up, and NEVER lower your calories during PCT, that is the surest way to lose everything you just worked for. Currently, my approach is to use solid doses of clomid to raise natural test as quickly as possible, keep cals the same as on cycle, and keep plugging away at the same routine/same exercises as on cycle. This may not work for everyone but I seem to do better at keeping strength if i keep doing the same exercises. If i see a lift decreasing in PCT and decide to switch it out, I will tend to find that the lift has suffered greatly when I come back to it.
