Target, I initially had the same thought about microneedle delivery. There is a microneedle delivery insulin approved for use in Europe somewhere, I believe. But the problem is as follows: microneedle delivery (if feasible) will achieve systemic delivery the same as an injection, it's basically a pain free alternative, but for our purposes, do we need the TB-500 to work systemically or locally? The microneedles deliver the drug to the vascular epidermis where the drug is "picked up" in the blood, so it's essentially the same as injecting it subcutaneously in the abdomen or anywhere else, the end result is the same, systemic delivery, not necessarily local delivery. Like the insulin you read about, it would not work to lower blood sugar if the delivery did not achieve systemic circulation. The reason the insulin had faster uptake transdermally than subcutaneously is because the adipose tissue is not very vascular compared to the epidermis, so transdermal delivery reaches systemic circulation faster that subcutaneous delivery. The question is, does TB-500 in systemic circulation serve our purposes for Penis Enlargement? I don't know enough about TB-500 to guess about this. I know Snake injects into the CC and clamps off in the hopes that he will maximize exposure to the receptors locally before going systemic, but there is a whole lot involved in drug/receptor binding (I'll spare everyone the details) that needs to be taken into consideration for his theory to be sound, and I'm not saying that is isn't, only that I don't know. Snake, I'm not questioning your work, you're a pioneer and we need more like you! I'll try to learn more about TB-500 to see if I can shed some light on how it might be best implemented for Penis Enlargement purposes. In the meantime, keep up the innovative thinking Target, it's inspirational!
