Having used both vendors, and used multiple compounds from each, I would take Opti over the other every single time. In fact, I refuse to order from the other source now; far too many inconsistent tests with customer tests showing totally different results from their own testing. Opti has great oils, great orals, and great GH. Only peptide of his I can speak to is his Reta, and it's solid as well. There are other excellent sources here, but amongst the larger sources, Opti is a standout. In my opinion, it's worth waiting a bit for him to open vs ordering from that other questionable source.
This unsolicited opinion brought to you thanks to Sunday afternoon boredom.
