I might be a little late to this conversation, but I've been using Monster for about 4 years now and have never had any serious issues with them. On one occasion, the shipping took a little longer than expected, and on another occasion, it took a little longer than usual to receive the tracking information. In both situations the reps were extremely helpful and acted quickly and thoroughly. Both "problems" were resolved within a day (for the shipping delay issue, I at least received a new and accurate ETA). Aside from those small incidents, I've probably placed around two dozen orders through Monster and have always received the products within 2-3 business days. The quality has always been excellent - I have not had any independent tests conducted, but I have a mirror and a workout log that includes lifts, weight, and reps, as well as rest times and TUT. Based on my personal experience, I am confident in vouching for the quality of the products. Finally, for a domestic company, they are very fairly priced. A jar of 300 mg Test E for $45 is as good as it gets from a legit domestic source. Anyway, to answer your initial question, in my experience, Monster is a safe, reliable, and quality company. Good luck, hope everything works out.
