Then give up.
No pheromone would change your personality for you. Let me tell you something that I have never told anyone because it is too personal. I have been raised in canada all my life starting at age 10. Before that I was in Kuwait and I didn’t have my parents around(they are divorced), my mother moved on with her life and left me and my 3 siblings living with the maid, and my dad ran away from the country because he was stateless and wasn’t allowed to work in decent jobs, he faked everything until he got to the US.
At that time I was 6 years old, my brother who is a year older then me has autism, and my sister was 3, and the youngest was 2. We went from one place to another with the maid just so we can stay alive. I have been raped, I have have experienced a lot of physical abuse and to this day there are some signs of that(I’m 28 years old 2 days ago) so if anyone here who has the right to give up and complains why life is so shit is my siblings and I. We suffered a lot as children but look at us now, both my sisters are married, I got married 2 years ago and have a beautiful son now. And no amount of pheromones would help us if we didn’t help ourselves first.
Be glad you are whole, alive, have money to spend, live in a house, had a better childhood, have a job. Now look at the people who don’t have any of those and see how You feel
I realized that when a person hangs out with people who have more than him, he becomes greedy and there is no such thing is enough, and if he hangs around his like or people less fortunate than him, he appreciates life more.
If you didn’t understand anything I said then you are just trolling and or too depressed and I suggest you go see a doctor.
As for pheromone advice, get away from the sexual mixes, and get the social mixes. Concentrate on instant shine, instant openness, p74 annnnnd a SMILE. People want to be around others to make them feel good and they would approach you if you smile at them. There is no such thing as an ugly smile. Concentrate on getting to know people and try to have a good time socially instead of thinking about sex or a girl friend.
What are you good at? why are you good at it? what do you enjoy doing a lot?, write them all down. Now write down what are you bad qualities and what personality trait you want to exude and then dedicate a whole month learning each one. If depression hits, go take a cold shower and go for a run or something. Yes, emotion comes from motion, once you change your physiology, your attitude changes. If you keep on doing what you doing in the past, you would keep on getting what you’ve been getting. Change how you live your life and I promise you everything else changes for the better.
You fix what is inside and your outside is fixed automatically guaranteed… Or your money back 
Remember to smile… Or go see a doctor.
Take care
