Sooo lemme get this straight, you have never heard of the lab, did no back ground research, and decided to pin it anyway?....Did you filter it yourself or at the very least shake it to see if it got cloudy due to water contamination? Also as a general rule I would be wary of the quality of any product that has a printed language on it other than the language of the country of origin....in this chase Chinese. You can actually find some pretty high quality near GMP gear in China, kinda grey market like PHs in the us, but I can assure you that the packaging isn't in English. Also another thing to note with this product is that the dates are printed on the label when it was made, not stamped on at a later time. This is yet another practice of both counterfeiters and low quality labs.

Side note: While an Aromatase inhibitor (AI) can be helpful when running multiple aromatizing substances, if you are only running one aromatizing substance and oestrogen related sides are manageable it is best not to use an Aromatase inhibitor (AI). In other words, use it when necessary. Most Aromatase inhibitor (AI) negatively impact HDL, thus if sides are manageable there is no reason to reduced them considering the long term cardiovascular risks associated with lower HDL levels. Don't take my word for this, but rather the word of my endocrinologist and pro coach.
