did u store the bottle in the fridge after?

Has anyone here used both of the following nasal peptide blends?

Limitless Biotech: N-Acetyl Semax Amidate / N-Acetyl Selank Amidate

Studz Peptides: Standard Semax + Selank

I'm interested in hearing from people who have personally tried both formulations, ideally for a reasonable period.

A few questions:

Which one gave you better results for focus, concentration, memory and mental clarity?

Which was more effective for anxiety, stress and mood regulation?

Did you notice a difference in potency or duration of effects?

Did either cause side effects?

Did you find the N-Acetyl Amidate versions noticeably better than the standard peptides?

If you've tried both, which would you recommend and why?

I'm particularly interested in genuine first-hand experiences rather than supplier claims or theoretical benefits. Thanks!
