Why work out for 1.25 hours? I would try and cut that back to something closer to 30-45 minutes. The cortisol you're releasing into your system by over working your muscles is doing more harm than good.

If you're trying to put on muscle, for extended periods of time is counter intuitive. It seems your trips are only 30 minutes, so you're fine there.

And I'd recommend cutting you're time at the gym down to 2-3 times a week. You need to let your muscle rebuild, and time is the biggest part of this process. You're likely overworking your muscles and never giving them a chance to repair.

I'd aim for at least 1-1.5g of protein per pound of lean body fat when trying to up your lean mass. If you need energy, tubers and starchy vegetables are miles better than bread. Avoid that one. Each sweet potatoes or so before hitting the gym. They're delicious.

What does your workout routine look like? How many reps are you doing? If you're doing more than 5 or so, you're not pushing yourself hard enough and need to up the weight. I tend to do 15 slow reps at a low weight, 8 medium speed at a medium weight, and then 5 as fast as possible at my max weight. This works the fast tissue muscle while burning the glucose out of the slow tissue. This will help you in gaining muscle and lean mass. You can do a couple sets at 5 reps, but if you're able to do more than a few you're not lifting heavy enough.

Also, don't do isolation exercises. All you need are squats, deadlifts, bench press, barbell rows, and upper presses. Make sure you're not using a machine when doing these things, either--you want to build your balance on your own. Pushups and pullups are also fantastic, but avoid curls and presses. It makes you disproportionate and not actually able to do what you want to do (like lift things!) in the real world.

Don't do cardio. Don't work out for more than 45 minutes. Cortisol = boo.

Good luck! Keep up the active lifestyle, but don't workout if you're tired.

I wouldn't add the bread. Whatever you do, don't add the bread.

How do you feel? Is there a problem?

If you're worried about too much protein, then I'd up the fat. Maybe from a plant source?

I'm going to keep my advice pretty simple. If you're trying to put on muscle, don't worry about too much protein. Protein is good for building muscle and not dangerous. If you're undereating calories, eat fattier cuts of meat (ditch the tuna and chicken, eat more beef). Also, add in more carbs from paleo sources - potatoes (sweet or white) - especially post workout. Do not add bread.

I would incorporate more fruit and roots/tubers. White rice isn't a bad idea after a workout either.

Eat less protien, around 130-170g should do. Up the carbs to a considerable amount, 300+g a day is a good amount if your trying to gain. Fill the remaining calorie gap with fat.

Your training regimen is pretty solid for gaining but you need to up the calories even more. I would personally go for 4000 at least. Getting enough carbs along with enough calories will really enable you to push yourself and make some nice gains.

If you're eating regularly enough and getting good quality deep sleep, working out as frequently as you do will not be a problem, as the food you eat will repair your muscle tissue. Don't worry about working out too much, your food plan will take care of the recovery. Also I would recommend adding a couple of scoops of casein before bed to facilitate even better recovery and HGH release. That way test levels will be higher while you sleep and your muscles won't turn catabolic.
