If you're hard gainer and you are eating plenty of carbs but still not gaining, look into your fat intake.
Start eating fatter cuts of meat, put extra spoon of oil in your salad or on top of your rice, full fat milk etc.
Try it for 4 weeks.

If that doesn't work maybe check yourself for worms. LoL

Lots of honest advice here, up the calories and hold off on the gear. Gear changes the way you handle nutrients, retain nitrogen...so if you're not getting enough food, dbol, test, etc won't do much.

Personally I'm a big eater, love to eat and never had a problem getting cals. I also know my appetite goes through the roof due to my training. One thing to do is to look at how you're training. Are you training intense enough? If you're trying to gain size hit the gym with a purpose, guarantee the appetite will increase.

Also, I'm more into whole foods than gainers. I feel like a lot of weight gainer shakes have a lot of excess "filler" in them. I like to make my own gainer shakes if I need some extra calories. Try this:

-2 scoops of whey protein (your choice, I've been into Cellucor lately. Mixes and tastes well and they have good quality controls)
-12/16 ounces of milk
-1 cup of oats (you can use plain or if you like flavor packets you can use a couple of them for whatever flavor you like)
-half cup of plain Greek yogurt (extra protein and digestive enzymes to help ease the burden of digesting this monster)
-heaping spoon of peanut butter (healthy fats. If you're in desperate need of calories, no need to count servings).
-If you feel like you still need more, add a banana or half of a banana.

That shake will give you some decent calories with adequate protein, carbs and fat. And with your stats and experience, the protein intake may be on the higher side of what your body can readily digest at once so you can sip on it between whole food meals (meals spaced every 2-3 hours) or you can slam it at once and treat it as a meal and just drop a scoop of protein powder until your body becomes adept to handling more protein intake at a sitting.

Just stay consistent with calories. Try these shakes, eat up some good whole foods that are calorie dense. Red meats, nut butters, healthy oils, etc. Try to be mindful and consistent with the intake, you'll notice gains.

There's an app called myfitnesspal. It makes it easy to count your calories. I've used it in the past, just wasn't disciplined enough to keep entering everything. I think if you used it for a few days it would be eye opening.

I highly doubt you're actually eating 3000 calories ed. I started out at you're exact same stats just a tiny bit taller at 22 years old and I have a fast metabolism and 3000 cals was enogh for me to bulk until I got to about 165lbs. At that point I needed to up it a bit to keep putting on size. And that was natural no dbol. You don't need steroids you need to track everythjng you put in your mouth and see how much you're really eating. I thought I was eating a lot at first until I starting tracking it and realized I wasn't eating close to how much I thought. Id bet any amount of money you're not even eating 2500 cals ed.

Up the calories, Eat high-protein high calorie. Eat every 2 to 3 hours...do this religiously and your metabolism will change. A dbol cycle will leave you at 5'10" 130 lbs and a dick that don't work

With all due respect you have not researched enough if you're asking about an all oral cycle. Every day on the site I see at least one or two posts of somebody talking about an all oral cycle. All of them ended the same...Bad idea
