First and Foremost
every day I do chest, bi, back, shoulders
I noticed that you didn't mention legs in your exercise regime.
Your legs are comprised of the largest muscles (muscle-groups) in your body. Disregarding them is at your great detriment. Moreover if your interested in increasing your testosterone levels naturally, it's well known that training legs brings the biggest increase to testosterone.
Considering that testosterone is the primary hormone in muscle growth, it's time to integrate those leg exercises into your workouts.
Also no abs and triceps exercises are mentioned...
I am 42 and have been working out for 2 months my primary goal is to bulk up
I am working out every day
Bulking up (training for hypertrophy) requires rest. Even if you don't feel sore your muscles still need time to fully recover (and Grow!). I would argue that if you can train the same muscle groups everyday at the same intensity, then your are not training for hypertrophy. You're also not training with your utmost intensity.
I spend between an hour and a half to 2 hours in the gym
It's not about the time, it's about the Intensity. Quality over quantity.
Take a shot of espresso if your working out when your tired, blast some pumping music and give it your all. Yell a bit of you need to (at your own discretion). Those guys (or girls) who are shouting at the gym are annoying, but they are (generally) putting some serious intensity into their workouts.
Workout 3 days a week
Each day full body - Include Legs! (Squats and Lunges are your new best friends)
Make it INTENSE
Take a fourth day for cardio
Change your Diet
Bulking doesn't mean your free to eat what you want, it doesn't go straight to your muscles (despite what the "bro-scientists" in your gym might tell you).
Stay away from fatty high carb foods (like Pizza), and sugar (no more Pepsi).
If you don't want to go to a nutritionist, check out the slow-carb-diet.
(Any considerable change in workout routine or diet should be discussed with your healthcare provider- or a certified nutritionist/Personal Trainer).
