, fat burning , Strength, intensity was there in workouts more than with str8 TRT with 200mg cyp. Sides as well. Sleep was affected negatively and libido was also affected negatively even at that low of a dose so had to add in pramipexole at just .25mg nightly. i must add on a positive note, its been 2 months since and i still see that my physique did benefit from tren for a full year at low dose, meaning looks like the muscle gains made are mature, permanent and solid. I chose this protocol because my prostate becomes slightly enlarged at just 200mgs tesosterone a week TRT by week 5. I think I would try 100mg/test 100mg/primo on my next experiment.
