it really is junk bro......
How is it junk, especially if he's happy with the results he has seen thus far?
I used Super Mega Mass 2000/Giant Mega Mass 4000 for the better part of 3 years when I was in college. And, it worked well for me. Is it the best weight gainer? Not anymore, as there are better products.
But back in the day, it was among the best on the market. In fact, the only gainer that I can say was better was the one to which I eventually switched, N-Large (and later, N-Large
2).
If G.R.H. is an ectomorph, in his teens or early 20s, he needs all the calories he can get to grow. And Mega Mass is as good a product as any to help him get it.
