There are no steroids that you can take forever without negative effects. Many people suffer from the issue you are suffering from. There is a lot you can do based on nutrition to increase appetite. Food choices. If you are eating a very clean diet, believe me, you will get very hungry. Chicken, brown rice and broccoli, eaten for each meal will get you starving after a week or 2. The key is, you have to work hard and with the same dedication to diet as you do to training and increasing strength in the gym. It does not happen over night, just like you dont bench 315 over night, but with time and dedication, it came be done. If you need some help and want to work with a professional, contact me through the Next Level Nutrition page, here at Naps. There is a lot you can do and you can "trick" your body into wanting and craving food.
Anoteher option is cardio. Cardio helps a lot to get appetite going. 30 min walking post workout will make you more hungry than you would be otherwise. There are so many changes you can make, but these are a couple options to start with.
And as for drugs, EQ which must be used with test, makes some people more hungry. I dont get it from EQ but some do. I have the same issue as you, so believe me, I know how it feels and I have still managed to consume 10k cal diets to push weight up.
Another option would be a shot of GHRP6. 250mcg to 500mcg gets many people very hungry. Try the nutritional options and then consider adding these drug options to help if you still need it.
