so ive read that LGD has binding affinity of 1nM and ostarine has 3.8 but what are they based on ? I thought everything was based on methyl tren which has ba of 0.20 and that test has ba of 0.80--so then I see they come out with RAD140 and it reads ba of 7nM vs 29nM for test--how did test go from 0.80 to 29nM?
