I am 100% all in with this source!! Everything went smooth as silk from navigating the website, to the payment process which doesn't get any easier, to the speed of shipping. Bought a kit of his Optitropin and ran a serum test. Attached are the results it scored an impressive 30.6. Testing protocol was the entire vial (12ius) taken IM in the delt with blood drawn 3 hours later. Solid result. Looking forward to running an IGF1 test down the road using nothing but his Opti's. Will report back once that is complete, but until then I'm stocking up and so should you....BUY WITH CONFIDENCE
