USAgScience is definitely very impressive. With regards to their Research SARMs Cardarine and Ostarine, specifically; there have been noticeable increases in stamina, greater endurance, and noteworthy body comp improvements. These all can occur without any focused changes to foods or supplementation.
The Customer Service is remarkably precise. Orders arrive quickly. Inquiries garner immediate responses. Jeff Behar has remarkable knowledge and experience that is reflected by the integrity of the products.
I highly recommend following Jeff Behar and/or giving USAgScience a try. Ideally both.
