You're not as bad as it seems, I'm calculating you are 185lbs @ 84kg and started at 127lbs @ 58kg. It looks like your weight has been miscalculated by 27lbs . You have put on 57lbs or 25.8kg since you started cycling.
My concern might still hold true that he has not figured out how to eat for his goals if he could not break 160lbs naturally at 5'10.
Each can walk their own road, but I am a fan of maximizing natural progress at least to some reasonable extnet prior to jumping on AAS. It took him 5 cycles to hit 185, I would question where this is all going.
I would suggest a simple lean bulk to 210 w/ 1lb per week weight gain. (500 cal surplus). This would be true either on or off AAS. If you want to progress you have to learn to eat for your goals.
You arent the first person ever that jumps on AAS early, but really figure out how to maximize your progress without relying on higher and higher doses.
Of course there are always your goals. If you want to be IFBB big, then sure, no one can hold that size without getting on and staying on significant doses. If you are looking to be fit and being such long term, my adive is slow and steady wins the race. I am approaching 50 and still hold 200+lbs lean at 5'9 >10 bf. I would be 225 at avg bf levels. Not huge by any means, but I can maintain my size and strength on a normal hormone profile and dont always need to be 'on' to be where I want to be.
In the end, let us know what your goals are. If there is one truth I have seen in the 20 years I have been in the gym, is people do not understand the power of food. It is the most powerful tool at your disposal. Even more so than AAS. If you learn to use it to your advantage, it will benefit you regardless of what path you choose.
