They have technically been around since the 50s but non steroidal SARMs are relatively new. 2000 time range. I’m waiting to see if the results stay when I get off cycle before I post them on my chart but I measured today and I’m up an insane .3 inch in girth since last measure. If they stay I will be shouting from the rooftops. If not then I’m going to do more testing on myself and report. Before the next cycle I will get blood work done and again after. I’m also going to do pre cycle halfway and 2 weeks post cycle measures. I measure 5 days in a row at the same time in the same room then take the average to post results.
