There's definitely some interest. Please start the process of expanding on that information.
Also is it cool if I PM you to talk about Cosmic?
I may have made it sound more exotic than it really was. the TL;DR is just that, after multiple misdiagnoses I was finally narrowed down to MDD. I tried SSRIs, SNRIs, I tried low dose naltrexone, I tried mostly everything. this began in.... 2004. fast fwd to 2012, I'm still on the hunt for relief. a year later I discover Cerebrolysin. by this point I was already a gearhead, so pinning myself wasn't an issue. I read a lot on Longecity about it, then researched it on various health databases and decided to try it.
I've gone off and on cycles of it (and by cycles I mean multi-week/month stints), but ultimately settled on continuous use. I'm happy. I've battled anxiety in my times off of it and the shit nukes it every time. this is a common effect, but isn't the case for everyone. I find that the effects tend to last for 2-4 weeks after stopping based on how much I've taken per day, but, the thing with me is that it really creeps up in a bad way and tends to be unpredictable. typical signs of depression - I'll lose drive, interest in stuff, sometimes get too negative about everything, etc. so I made the choice to stay on for good. I use 3mL per day and that treats me pretty perfectly. (i'm 265-270, but cutting now so that might reduce over time. I'm aiming for 225-230 and single digits, far from that now lololol).
as for Cosmic, they're overall great. I've had a handful of issues with orders with them and they have pissed me off over them but they always send me coupons for 15-20% off to make up for it. add that to the 10% off for crypto and it works out well for me. US shipping is fast. RU is 15% less cost but will take the extra time of course. You will never have issues importing the stuff, it's 100% legal to own and use in the USA.
i'll say this. even when i was off the stuff (like in between cycles) my brain was completely different than before ever having used it. orders of magnitude better. my first and second cycles were AMAZING, oh how I wish I could have that experience every time.
last point. Memantine is a drug I used briefly when was off Cerebro. I got a script for it. NMDA class drugs are one of the more exciting developments in psychiatry IMO and will help a lot of people who like me have been failed by all others thus far. Ketamine acts upon NMDA receptors as well IIRC, and it's making a fine debut to the world of treatment. Memantine was difficult to dose correctly for me, and ultimately the sleep disturbances were too much, but it's a shame because otherwise i loved the stuff. Totally destroyed my anxiety and my negative head noise - or what is left of it.

my dose seemed best at 15mg per day, but, still, the lack of REM sleep is something I'm still trying to recover from.
hope this helps. I never found much use in therapy once I realized what was really bothering me about my life, which cerebro certainly helped me see pretty quickly. from that point on it's a matter of acceptance and ingratiating within yourself that you need to change things. downhill journey from there.
