Hi everyone, Yesterday I decided to pop a pink NASA 2cb rocket (25mg). The first time I did 2cb was nearly 18 years ago so this was the second time and overal I was never really into doing psychs anyways, so I thought it was time to give it a try once again.

Summary
4-Bromo-2,5-dimethoxyphenethylamine (also known as Nexus, Bromo Mescaline, BDMPEA, Venus, and 2C-B) is a novel psychedelic substance of the phenethylamine class. It is perhaps the most well-known member of the 2C-x family, which are structurally related to the classical psychedelic mescaline. The mechanism of action is not fully known, although serotonin receptor binding activity is thought to be principally involved.
Perspectives
“2C-B remains one of those substances that defies easy categorizationβsimultaneously stimulating and relaxing, visual yet lucid, euphoric yet manageable.”
“A day at the Stanford museum. Things were visually rich, yet I felt that I was reasonably inconspicuous. The Rodin sculptures were very personal and not terribly subtle. I saw Escher things in the ceiling design, when I decided to sit in a foyer somewhere and simply pretend to rest. Walking back, the displays seen in the bark of the eucalyptus trees, and the torment and fear (of others? of themselves?) in the faces of those who were walking towards us, were as dramatic as anything I had seen in the art galleries. Our appetites were enormous, and we went to a smorgasbord that evening. A rich experience in every possible way.”
“Overall, this was a good experience. I can see how some people confuse it with MDMA, but I found it to be less empathogenic and I was much more body conscious.”

bro. im mad cuz I cant tell anyone irl abt this bc my only drug friends r dudes. and I'm a chick so that's weird. but I took a 15mg 2cb pill by myself a few days ago for the first time.
Wow! What an amazing experience we shared last night. Started low and slow as this was our first 2C-B trip and now looking forward to the future and exploring more. For all of you who share your experiences on here, thank you.
To kick off this tale, I was 17 and deeply immersed in the world of psychedelics and cannabis. My mindset was undeniably experimental, having indulged in acid numerous times at excessively high doses and thoroughly enjoying the experiences.
Iβm currently in Costa Rica and decided to sit with medicine today and I ate a mushroom chocolate with 2.5 g. Unfortunately my stomach did not like that and I puked all of it nearly 20 minutes after I ate it and lost desired effects. I had some mushroom honey, not sure how much.
Hey all, itβs a beautiful spring day today and I have a g of powder that has gone untouched for about a year because Iβve been too anxious to try itβ¦ but I think today might be the day! Really I want to try it now because I want to take it at a convention next weekend in lieu of...
I was hanging out with a friend, and she asked if I wanted to try 2CB. She said it was like ecstasy without a comedown, and would only last for 5-6 hours. I was nervous because I had been under a lot of stress, and also because coming up on MDMA is very unpleasant for me.
Popped two 24mg pills and had a really good trip that was super introspective and pleasant, right on the tail end of my comedown I smoked half a joint thinking it wouldnβt be that bad, spent the next 4 hours in the worst trip ever, pure anxiety and visual intensity without any eu...

Synopsis: Experienced tripper has his first worthy sexual experience with 2C-B, but only after letting go of desires and expectations and inviting an energetic entity he refers to as his 'ghostly lover'.
I had rented a cabin in West Virginia as a birthday present to Sam, hoping to relive the wonderful LSD Βtinged cabin trip we had taken in January. I still had two 25mg capsules of 2CΒB Hbr that I had weighed out the previous weekend and never eaten, so we decided to take those.
Preface: I could never have imagined a more perfect setting would present itself. My friend was back at his parentΒs house in the suburbs, a place familiar to me since I was 6 years old, a place of comfort and pleasant memories.

2C-B Teaches Me to Be 5:25 PM , 18mg 2C-B Will do this in a bit of an odd format, the note followed by my memory of the experience near the note. Seems the most convenient. Took a measured amount 18mg 2C-B hcl, I have an extensive history of psych use in the past include LSD, Al-Lad, 4-ho-mipt, MDMA.
Substance: 2C-B Dose: 25 Milligrams / Yellow MTV Pressed Pill Setting: California Desert during Early-morning/Sunrise. Date: Spring 2004. 12:30 AM. I had been looking for 2C-B for many years prior to this event. Since I learned about it in 9th grade, I had always been interested in this chemical.
I've been meaning to post to this site about this experience since it happened - but initially it was too close, and then having not been so much in that world lately I haven't thought about it.
I am a first-time 2cb user and the powder is in a capsule so I do not know the exact mass of the substance. However, based off of the trip reports in Pihkal (Shulgin), as well as numerous others, I am going to estimate that each capsule contained 10-15 mg.

I haven' t read a lot of trip reports yet. I don't know if somebody wants to make fun out of mine. It was a very personal experience, hard to understand if you're not me, nonetheless so beautiful that I had to share it! My story is very detailed, probably because this is one of my first psychedelics experiences, and I'...
This will be my first trip report in a while, its been some time since i last wrote one so bear with me, and excuse my mistakes. Im in my late 20s, with a little over a year of experience with varios substances, a vast majority of them being psychedelics.
Having had my thread closed I actually rang said dealer and have had it confirmed that it was 2c-b, which is fine by me. really dont see how not being sure is a problem, and why people cant still enjoy the report, i see many report titles with ??? in them that don't get closed.
22/04/2004 Set : I have been in another one of these phases where I get too many possible chemicals in my hands, and just go a bit too hard on experimenting. Still trying to find what's missing in life in the wrong ways (by abusing psychedelic drugs).
Substance: 2C-B (4-bromo-2,5-dimethoxyphenethylamine) Dose: ~25 Milligrams / Yellow MTV Pressed Pill Setting: California Desert during Early-morning/Sunrise. Date: Saturday, May 1. 12:30 AM. It's been a couple of months since this experience, and I meant to post this up much earlier, but I enjoy slacking off.
This is actually really, really long. I don't know if anyone is actually going to want to read this, but you can just skim through it. I really wanted to write this just so I never forget this experience. Me and my friend had two 25mg capsules of 2c-b.
A group of about eight of us, a few are perviously experienced in 2CB, LSD, MDMA, Mushrooms etc got together initially to have a drug free party... Alcohol mainly, but some may smoke weed. I do not smoke anything and drink occasionally.
