Since there's no source or brand talk, I'll comment on your other question rocco. Eq is one of my favorite compounds, I've used it successfully to cut, and make gains. Many benefits with this hormone, better O2 capacity, increase in red blood cell production, little to no conversion to estrogen, in my experience. General feeling of well being improvement. Unlike the popular consensus, I also don't need to use up to or over a gram per week to see progress I've done well using 500mgs weekly. Like any or all the rest aas, proper diet and nutrition is the determining factor. Either cutting or adding mass it's lean, hard muscle tissue with better vascularity. And that's my 2¢ friend...

First, there is no source talk in the open forums. That is what the SI pages are for. Use the search function up top and you'll answer both of your questions.
