Seems to act differently depending on route of administration. If you've ever had weed, it's like edibles (injecting) vs. smoking (nasal).

Intranasal is more cerebral, "in your head" type of effects.

Subq is more bodily, "all around your body" type of effects.

If you're looking at it as a nootropic, I would recommend the spray. It feels similar to prozac and wellbutrin, if they weren't so terrible.

If you're looking at is as an anodyne or body-anxiolytic, I would recommend subq. If feels like baclofen.

I guess I'm a little confused by your answer - are peptides nootropics or sensation-type experiences? I guess I perceive nootropics as like "become smarter" or "having better recall" but this answer makes it seem like a recreational time bound physical experience? I also could see how the mental and physical have blurred boundaries.

I'm nodding off right now, so my verbal fluency is off. I think I was trying to make an analogy on how their effects differ, not on how their effects are.

For example, with eating weed, you get bodily sensations, and so its effects are more on your body, i.e. physical; while with smoking weed, the "sensations" are more in your head, and mental.

Likewise, with injecting NASA, the effects seem to be spread around your body and more "physical"; while administering NASA intranasaly, the effects are more mental, and focused "in your head."

The route of administration changes the expression of the drug on your body and mind. Dependent on that, it can either be a nootropic (nasal route) or akin to a mild and sensationless (compared to painkillers like opiates) muscle relaxant (subcutaneous).

It's difficult to explain, because the effects are so mild and without the normal "Oh, I'm on drugs. I can feel it" sensations, that you can only see them in hindsight (in my case, by perusing old journal entries).

Are there short and long term benefits as far as memory and what not?

Uncertain. Likely nothing noticeable.

Only thing in the vein has been a better ability to plan, reason about in my head, and make use of visualization to reason about problems (and their solutions).
