I recently purchased CJC 1295 through RUI Products after reading positive reviews of this company on this board. After injecting my lab subject with a dose of 2 mg of this peptide, there was no noticible flushing effect. This seems contrary to what other researchers have observed. Is this something that I should be concerned with as to the purity of this peptide or is the flushing effect subject dependent? Also, not that it matters but I noticed that the cc charges for the purchase of this research chemical were to a Chinese company called Healthycenter Shenzhen.
