I have had no luck identifying the legitimacy of MC Labs products: Masteron 200, Tren E 100 and Test E 500. I can report that there have been some blood tests which might infer contamination in their products. Dosage is also being questioned. I have attempted to contact SIMEC AG for a full review, but, unfortunately, I have not heard back from them. This could be due to the COVID-19 restrictions. ANY knowledge or help appreciated.
