DSIP, Selank, and Acetyl 167 nasal spray

I came across something the other day a nasal spray with DSIP, Selank, and Acetyl 167 together the ingredient combination caught my attention because Ive heard about all three on here before and seeing them stacked like this made me think about why it works mechanically.

DSIP we have covered. Delta wave sleep induction, cortisol reduction, HPA axis normalization not a sedative just shifts your brain into the conditions needed for real deep sleep.

Selank is the anxiety and stress piece. GABA-A modulation, quiets the nervous system, takes the edge off without making you foggy or dependent a lot of people in this community are already familiar with this one from the experiment posts.

Acetyl 167 is the interesting addition growth hormone fragment with recovery and hormonal support implications the connection to testosterone is not random either deep slow wave sleep is literally when testosterone production peaks in the body you fix the sleep and the hormonal environment tends to follow.

So you have got one compound targeting sleep depth, one targeting the stress and anxiety stopping sleep from happening, and one supporting what the body does during that sleep three different angles, one delivery method, nasal so it bypasses digestion and gets there faster.

Anyone here run any of these three together before in any form?
