Thanks! It's hilarious that even people in the comments can't agree, when they think they're agreeing with him. It's interesting that he complains about getting garbage, but doesn't just send his own vial to Janoshik from one of the more reputable sources for $300. The prices are as usual 10x for the vial vendors.

All the medical commentary I've seen suggests it has the longer half-life rather than 10min Ryan claims because,
"...they added a 13 amino acid tail to the end terminus, hence long. And replaced the glutamic acid that was in the third position with arginine, giving you R3... What's fascinating about this is normally additions to the molecule extends its half-life...Those changes to the peptide reduce its affinity for binding proteins by roughly three orders of magnitude... LR3 rarely ever binds to binary proteins. So, it's definitely not going to make it to the ternary complex step. It's not going to last anywhere from 12 to 24 hours."
Journal of Pathology says,
"To determine the effect of continuous administration of Long R3 IGF-1 [an IGF-1 analog with an extended N-terminal tail and Arg for Glu substation at position 3, leading to a prolonged half-life (20 to 30 hours) due to decreased binding to IGF binding proteins] on early atherogenesis or advanced atherosclerotic lesions... During treatment, plasma Long R3 IGF-1 levels were measured by a human ELISA kit (Gropep). Plasma total cholesterol levels were measured spectrophotometrically using enzymatic procedures, and triglyceride levels were quantified using a commercially available kit (Roche Diagnostics)."
Insulin-like growth factor-1 (IGF-1) signaling is important for the maintenance of plaque stability in atherosclerosis due to its effects on vascular smooth muscle cell (vSMC) phenotype. To investigate this hypothesis, we studied the effects of the ...

Not sure it really matters since bilateral isn't that much more of a pain in any case. Now if bio-availability or degradation in BAC was <5min that would really push to AA reconstitution.
