IMO, pharma product is the only way to go. It can be had inexpensively from international pharmacies. Research Chems are far too easy to fake or under dose. Anyone with a few bucks to buy blue glass bottles and set up a .com can be in the research chem business in a few days. It's all way too sketchy for me.
Obviously pharma product can be faked as well. It comes with it's own inherent risks, and a higher price. But, I'll gladly pay extra every time for genuine pharma meds.
