Has anyone tried Semax for depression after SSRIs didn't work?

[YukiWay]

Anyone here with hands-on experience of Semax, or another peptide, when SSRIs and herbal options had already failed? My partner has fought low mood, mild to moderate, in waves ever since childhood at school. SSRIs never worked well for them, and we are running out of standard options, so we are looking at alternatives. If you have taken both an antidepressant and a peptide, how did the two compare for you? Anything you would recommend, or steer clear of? I know everyone reacts differently and nobody can promise anything. I am just hoping to learn from people who have actually been through it rather than from marketing pages. Any details on dose, how long it took to notice a change, and side effects would be very helpful. Thank you in advance for reading.
