Ok so if you are thinking 8 wks, sure Sust would be a good option. Prop may be a good option too if you wanted to do something else. Either would be in and working fast. NPP would be an option. Something like Anavar would be another great option. Just 40-50mg ED for the whole 8 wk cycle would be fine. This will produce some great strength, improve recovery like other gear would, plus I feel its an easier one to recovery from. NPP isn't always hard to recover from and if you kept it at 4 wks, that shorter time frame would help with bouncing back but it still is a 19-Nor. So my thought on Var is that it would work fast, not cause a bunch of water weight and may be easier to transition off of when you go back down. But your plan is just fine too. Mainly, the thing you want to look at with shorter 8 wk cycles, is to probably use faster compounds that will give full benefit within a shorter period of time
