Tren and Deca are both nor 19’s. If you have used Deca before I assume you have done so while avoiding Deca Dick and thus your continued desire to use it. However, compounding 2 nor 19’s [the gear most associated with severe shutdown] is potentially asking for trouble.
I strongly advise against the use of Tren and Deca concurrently. Furthermore, I’m not even a fan of kick starting a cycle with Tren and then switching over to Deca for the duration.
Also your suggested dosage was 100mg of Tren a week. If you ever run Tren you’ll need to know that is less than 1/3 of an effective dosage. Entry level doses are usually 50mg ED for Tren Ace or 200mg twice a week for Tren E. Obviously some guys use quite a bit more these are the minimums.
IMO you need to pick between Tren and Deca others might differ in opinion.
Finally, do have something against Test. Adding 500mg of Test a week to your Winny and Deca or Tren would make for a very nice cycle. If you prefer EQ due to the lower aromatization don’t worry too much. 500mg is well tolerated by most individuals. Or just run a very low dose AI
