Nice man
You are the perfect example of what people can do to build a foundation before drug use.
Thats a solid base and still growing .When (if) you do decide to juice you will explode and see awsome results.
At one time I was very similar to you I grew from 135lbs to 185lbs in 2 years with out a single drug from age 17 to 19 and people assumed I was on the juice.
When in fact i had never even touched a drug at that time.
So I know for a fact exactly what can be done with will power dedication and compound movements.
(admitted the 50lbs I gained in 2 years was very blocky from doing squats,Bp and deads but it was a perfect foundation)
You are making excellent progress keep up the work . eat eat and keep eating
worry about scuplting and polishing out the muscles later.
The first years are so important it's make or break for most.
What ever your doing is working so keep doing it !
