1-2 lbs I would still consider to be doing very well! That's 52 lbs a year if only 1 a week! I agree with the initial bloat, but just because you are gaining LBM, it doesn't always mean it will show in your arms, chest, etc right away.
I have to ask, why did you decide to run Deca for only 4 weeks? I did this myself in my very first cycle YEARS ago and deemed it a complete waste by the time I was done. The half life is so ling that I feel like it's just starting to get going by week 4....maybe. Personally I think you should have stuck with Tren from the beginning to avoid the bloat and "artificial" weight gain. You can bulk with tren just as easily as you can cut with it. Adjust your calorie intake and frequency accordingly to achieve desired results. Remember this when you are contemplating the next cycle, just a suggestion.
Also, how well do you respond to Tren? When you cut the test to 100mg weekly I would consider running the masteron and tren near the same dosage as this seems to have a greater effect than one high and one low. Even if you just bump the mast to 300 and lower the tren to 500 I think this will make a big difference for you as far as hardening up and gaining aggression in the gym (as well as the sexual benefits from masteron).
