I'd like to write a bit on selegiline (deprenyl). I'm a 26 year old 83 kg male from Istanbul. Sorry for my (probably) bad English. I've been using the brand name drug SELDEPAR for about 3 weeks. I've been taking about 2.5 mg every day. Some days I took 5 mg, some days none.

Summary
Selegiline is a selective, irreversible MAO-B inhibitor at therapeutic doses (5-10 mg/day oral), used for Parkinson's disease and major depressive disorder. At higher doses (>20 mg/day), selectivity is lost and it inhibits both MAO-A and MAO-B, increasing risk of hypertensive crisis with tyramine-rich foods. The transdermal form (Emsam) is used for depression and has less dietary restriction at lower doses due to reduced first-pass metabolism.

Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 7.5 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.

First off, I'm a 19 year old male, about 170lbs, who is experimenting with nootropics out of curiosity. A few months ago, I ordered a bottle with 60 doses of 5mg Selegiline from a research chemical site and took it pretty much every day. The day I started taking it I noticed a marked increase in motivation.
After 42 years I had to face the sometimes debilitating depression that was affecting my ability to function. Rather than see a conventional MD I found a clinical researcher that was testing new drug therapies as part of FDA approvals.
The problem with legal drugs is that there's usually not much to talk about. Deprenyl is similar to an extent. I've experienced nothing truly unusual while using this product. I began taking Deprenyl as an anti-aging agent and a smart drug.
I'll be 60 years old next month and have been using Deprenyl for about the past 10 years. In most respects it's difficult to quantify the effects of this compound: in terms of its reputed anti-aging benefits I can say that I am very active, never get sick and am still alive.
Well, I tried deprenyl as a 'smart drug' years ago and I also did it 'recreationally'. Tried it as a smart drug while I was taking some classes and couldn't handle it for that purpose as it overstimulated me and caused insomnia. I Did the rest of my supply 'recreationally' over the next few years.
I have depression, anxiety, social anxiety, OCD. I have tried many medicines the doctors have given me. One day my doctor gave me a box of EMSAM patches, 9 mg each. I tried them for a couple months, one a day, and I felt nothing. No improvement was evident, I felt just as tired and anxious as always.

Alright, so I've been uber-curious about this mysterious substance for quite some time now. Everything I have read about this drug on BL has been excellent, so I decided to give it a shot to see how well it does as an anti-depressant.
Howdy folks, Long time lurker, though I rarely post so I apologize if Trip Reports is a more appropriate place for this post. I've seen a few threads on the PEA-Deprenyl combination, but no hard proof or first hand info. So here's a bit from the perspective of someone who's tried it all.
