Were you dropping weight intentionally? Take a look at your diet because your just spinning your wheels if its not where it needs to be to grow.
As far as programs go, my personal preference has been to never follow anything strictly to how its written. My philosophy is how can anything anyone else writes apply directly to me, or anyone for that matter. There are so many different variables that need to be taken into consideration, and fact is no one can take them all into consideration except you. Granted, I do have an education on the matter its still possible for you to grasp the simpler concepts and approaches needed to succeed without blindly following someone else's template.
Take the information in the programs for what its worth and experiment with some different training principals and approaches. Look at your results then ask yourself, are they favorable or not? Build on everything from there as your knowledge grows so will your body and understanding of what is happening and why. The same principal can be applied to your diet. It goes back to the simple concept, give a man a fish and he eats for a day, teach a man to fish and he eats for a life time. Guaranteed you follow 5/3/1 make some decent gains but end up plateauing soon after and come back and say, "ok what now."
Now I'm not saying just throw a bunch of sh1t together and hope it works, read and understand the concepts and the effect they have on your physiology. Then apply as you see suited from there. While a lot of the templates out there are great and will yield results, they are so often followed blindly with little to knowledge to why the individual is doing what he or she is doing in the first place. Bottom line is understand what you are doing, should you choose to follow a program or experiment with concepts on your own, and why otherwise your on a road to nowhere. You can incorporate sarcoplasmic hypertrophy targeted exercise right along side strength targeted exercise, you just need to have clearly defined goals and a method/understanding to why you are doing what you are doing.
