Not to take away from your thread, but I had a similiar structure to you when I was around your age. Im 35 now.
This was me at 16, after 2 straight years of training (my growth was painfully slow, but didnt have alot of money and biked 7 miles each way to the gym, moved furniture almost daily)
Id be glad to provide you with any guidance. Come post in the journal here on elite or PM me if you have questions. Its never worth taking anyones advice as fact, but Im sure you can gain some knowledge through my 21 years of lifting experience.
I wont post after pictures, but you can see the video and all of that in my journal. Not looking to hijack your thread. One thing Ill say is, dont be fooled by alot of the bullshit out there about people saying you need massive anabolic doses to get big and that you need 400 or 600 grams of protein daily. I can still grow on 200 grams of protein or less, aslong as my carbs and calories are sufficient, and thats on an HRT dose of testosterone weekly, after 21 years of training.
Just to put things in perspective. My results were painfully slow, so its not that I have exceptional genetics. My shape is decent but thats about it. Remember that taking more drugs means an equal negative trade off. You will in turn need more drugs to maintain that chemical built muscle, you will lose motivation anytime you go off or lower the dose and you will never build a solid base and foundation. You can become very dependant on chemicals that way. Id wait til you hit around 30 or so before you consider maybe doing an HRT dose, if you are going to ever go on. If you experiment with anabolics, no need to go crazy with the dose. You should just be looking to do whats needed to make steady progress. Most of the time its because youre not eating enough carbs and calories. Thats the hardest part.
Protein is marketing bullshit. Thats one of the main products that supplement companies sell.
If you think that I have decent size and strength, then it should be achievable for you as well without taking alot of hormones and with slow steady progress.
KEEP KILLIN THAT SHIT !!
