I did 2000 mgs of Propinate and 1500 Mgs of Cypionate per week interchanged with same amount of Enanthate [cyp for enan] for many months way back when and didn't suffer from bloat, even if my sodium was high or diet was briefly out of whack.
Some guys bloat and some don't.
Maybe you don't have Propionate? Maybe its Cyp or Enan (fake Prop)?
Try injecting every day and see if this cures the bloat. Give it two weeks and let us know.
