A peptide that modulates VEGFR2 in a cell culture dish, or heals a rat tendon at 10 mcg/kg IP injection, has not been shown to survive oral delivery in a human at 500 mcg and reach musculoskeletal tissue at any meaningful concentration
250 mcg 7.5 units and 500 mcg = 15 units on a U-100 syringe
Instead, theyre experimental compounds that are typically sold through gray market online storefronts and often labeled for research purposes only.
