Hey bud, got your PM obviously few things
1) Why test prop instead of a longer ester. 16 weeks is an extremely long time for a short ester cycle. You are going to turn into me in regards to scar tissue.
2) HCG weeks 10-17. 500iu per week (250 2x). I have read some things stating that longer periods on HCG actually creates a negative feed back loop further suppressing you.
3) Aromasin is great, if you experience little to no estro related sides I would kick it up to around 200mg EoD
4) Something to regulate SHBG might be good for a longer cycle like this.
5) If you are interested shoot me another PM, blasting IMO is a far better approach to cycling. I have been on non stop for around 5 years now and really wish I went that route instead of doing longer cycles like the one you have here.
