For some reason, my spidey senses are tingling about your diet.
For a rough calculation of the calories you need to put on muscle, multiply your weight by 18-19 kcals per pound of body weight.
In your case this would be 3636-3838 kcal/day
To lose weight, this rough calculation is 12-13 kcals per lb of weight so 2424-2626 kcals/day
You are eating just above maintainance would be my guess, and if you are training intensely, it is probably not enough.
There are more accurate ways based on height, weight age and/or bodyfat on this thread

Have you actually worked out your calories? Exactly, or are you guessing? A lot of lads underestimate what they eat, women seem to overestimate.
No mention of veggies.
There also seems to be a long period between meals.
I would focus on diet, supplements are just that, supplements.
Trying to build muscle when your diet is dodgy is like putting scooter oil in a forumula one car and wondering why you are not going fast.
The other thing that has me wonder is that you are spending 1.5 hours in the gym.
What are you doing during this time? Is that all weights or weights and cardio?
How many days a week are you training?
