r/2cb

Hey there

Going on a 3 days psytrance festival in a couple of hours, planning to insufflate and take oral 2cb during most of the festival (and a bit of weed and ket)

I took 2cb a few times and never felt nausea but I've always took it on an empty stomach, I get nausea on acid though

I am wondering how do you guys plan your meals at a festival given that it is recommended to have an empty stomach for tripping....

Also, I don't want to skip too many meals as I have a diet and feel like eating could help the body for recovery

I will try to find some ginger to help

Thanks for your advices :)

Substances: LSD (150 µg), MDMA (100 mg + 15 mg booster), 2C-B (12 mg)

Timing:

• T+00:00: LSD (150 µg, oral)
• T+04:00: MDMA (100 mg, oral)
• T+05:45: 2C-B (12 mg) + MDMA (15 mg booster, oral)

Setting: Alone in my freshly cleaned bedroom at my parents’ house. It was a quiet winter night, everything still.

Background: I’m a high school senior, 18, not on any meds or supplements. I’d already had about ten psychedelic trips (one heavy LSD ride, a Candyflip, a Nexusflip), so I wasn’t exactly new to this.

Mindset & Motivation

I’d been hearing about the “Ali Flip” nonstop. It was all over those French psychonaut forums; everyone called it the holy grail, even better than your usual combos. A bunch of other internet folks talked about it like it was the peak of trip chemistry. Since I’m obsessed with pharmacology and dead-set on pharmacy school, I was drawn in by all the geeky science behind it.

What hooked me was the theory: LSD lays down this intricate foundation, painting wild visuals and pulling your thoughts inward. When you’re peaking, MDMA barrels in with a rush of serotonin and dopamine; suddenly, the acid trip feels like it’s wrapped in warmth and pure joy. And just when MDMA’s magic starts fading, the 2C-B lights the visuals back up, bridging everything smoothly with no hard comedown or rough edges.

I wanted to know if that legendary synergy was real. So I went in fully focused, a little in awe, hoping to see something amazing but with plenty of respect for what I was getting into.

Preparation

For three weeks leading up to it, I got myself ready:

• Mind: Meditated every day, kept my intentions clear, tried to stay centered.
• Environment: Cleaned my room till it shined, weighed the doses by the milligram, made sure I had zero plans for the next day.
• Safety: Told my parents I’d be “introspecting” in my room all night, just to keep them chill. Set my phone lock screen to: “I am under the influence of drugs; what I am experiencing is not real, and I am safe.”

The Experience

T+00:00 to T+03:30: The LSD Foundation

I dropped the 150 µg LSD tab on a chilly afternoon and took a hot shower to get comfortable. About 50 minutes later, sitting on the bathroom floor, I noticed the linoleum patterns twisting into these playful, giggling shapes: a laughing elf, right there with me. I started cracking up, and all my nerves vanished.

Back in my room, LSD went full force. Light halos, morphing furniture, my phone screen ballooned into neon graffiti. The ceiling lights became cosmic eyes, then shifted into a proud Native American chief in a geometric headpiece. Closed my eyes, and I was off wandering through shining Egyptian temples.

My usual stress about exams and pharmacy applications started poking at me, but I let it go. The second I surrendered, a warm wave hit my chest. Suddenly, I felt weightless, tied to everything around me.

T+04:00 to T+05:45: The MDMA Launch and Ego Death

Four hours in, I took 100 mg MDMA. A half hour later, a deep warmth started in my core and spread; old tension just melted away. The euphoria slammed in, I tossed off my covers and stood up, like I’d shot into orbit.

Lying back in bed, my ego dissolved. There was just awareness: skin breathing with the room, everything united. I met this wild “God of Time,” a huge triangle with cosmic eyes floating in the clouds. Suddenly, I merged into this glowing river: life, death, all mixed together. Fear was just gone, replaced by pure love for my family and the world.

T+05:45 to T+09:00: The 2C-B Magic & Golden Landing

As the MDMA started fading, I popped 12 mg 2C-B and a tiny 15 mg MDMA booster. That’s where the magic happened: no harsh comedown. 2C-B fit right into the glow, snapping the visuals back on without overwhelming. Everything became soft, pastel, playful, like stepping into a happy dream.

More triangle-headed beings, animal forms, wild geometry. Touch felt strange, like my fingertips dipped in liquid. Music painted visions of ancient Mayan, Greek, and Asian worlds. And when morning snuck in, I drifted into the gentlest sleep, still wrapped in the afterglow.

Reflections & Aftermath

Honestly? The Ali Flip earns my respects. It’s the joker of psychedelic combos. LSD opens the world, MDMA covers you in love, and 2C-B turns the ending into a rainbow landing.

No rough patches, no draining crash: just solid harmony the whole way through. Compared to Candyflip and Nexusflip, the Ali Flip destroys them, blending the best of both.

The best part? The change stuck. All my self-doubt vanished, my drive for studying came roaring back, and my social anxiety? Just gone. This wasn’t just another trip: it was the most profound and beautiful thing I’ve ever experienced.

It could be that my milligram scale is fucked up beyond repair or I should seriously get my drugs tested. There's something wrong with my stuff.

23:20 the fun beginnins. I draw myself a line of my newely acquired 2cb. The measuring part was a part of great inner debate throughout the entire experience.

My milligram scale said something between 15 and 20mg. It didn't look like a lot compared to the whole 1g of this motherfucking beast i just acquired. Grounded up in to snortable lines it begun to look quite hefty however.

So i smartly decided to snort only half the line expecting a subpar light experience, maybe some tingling in my balls or some shit. But as I soon came to realize I was in for a fucking adventure.

I sit down after snorting it and turn on The Binding of Isaac to distract from the nasal pain (idk why I thought it would be a great idea, I'm addicted to the game ok)

23:25 as I'm stll hardly stomaching the pain of insuflation someting else suddenly became hard to stomach as well. The contents of this stomaching has little relevance since it shortly ended up in the toilet. I was dry heaving and hollering, Jesus Christ what did I just ingest that is liquidizing my insides.

23:30 i stand up trying to comfort myself that this is just a strong comeup, however odd it might seem but something uneasy kept me pancing around my room

23:35 im begging to feel it even more, even more throwing up questioning what the fuck i just took? was it the right drug? did I dose incorrectly? Does my girlfriend love me? Does my dog even know what my real name is? What even are questions? LALALALA?

23:40 So at around this time I completely and utterly lost my mind. However I was still lucid enough to desperately find a midazolam I knew I had stored somewhere for times like these. But the problem was I was tripping so damn fucking hard I didn't know what the fuck I was looking at. All the shapes in my room were connected to the other shapes.

Everything was melting into a visionary goo, there were a million of imaginary particles in that goo, from between which I was attempting to locate 1 small pill.

23:45 the height of my anxiety has reached it's limit, my body felt like it was going to burst but final to some miracle I found my midazolam pill. In the exatc space I was looking for it for almost 10 minutes. After swallowing it and with help of sheer will and determination I somehow managed to hold the pill in my stomach without throwing up some more, the luck was finally on my side.

00:05 still tripping out of my mind but now im also buzzed by a benzo so its cool.

00:30 I think all of it started to die down a little, I'm definitely enjoying myself now but the fucking hell I just went through makes me think this entire experience definitely wasn't worth it. People take this thing for fucking??? I can barely keep my reality intact while on it

01:45 The effects almost completely died down. It's my day off and I'm debating if doing another could feel good. Or at least better than that 15mg hellhole i just came out of.

I'll be trying 2cb soon and I've heard boofing is good. What if I do that with lube and a plug to keep it on place? Is that advised? I've never boofed anything. Is 15mg too much for this?

Just wish I had more nitrous lol

This will be my first time trying 2cb and was gonna trip with my friends (some will be doing acid/mushrooms) my question is will half a 25mg pill be a good starting amount then just redose as needed throughout the night to have a intense trip. Or should I just take a whole pill at the initial dose

i have labeled as 24mg pills. ik this isnt accurate so how much of a pill should i snort for my first time taking 2cb?

Hi.

We've never taken it before (quite a bit of weed and MDMA though) and I hear it's very dosage dependent. Would it work to take half a tab then the other half after, say, an hour if it feels OK? Would that dull the effects?

I've noticed that this drug can feel different at the same doses, and I feel this drug impacts everyone differently. Insuffulated, 5mg and my partner is tripping sack, I take 5mg and it's a chill time after work with no visuals. I don't even get visuals until 12mg.

Insufflation also hurts my partner and a lot of you guys, meanwhile to me it's just slightly worse than ketamine which is the only other thing I've put up my nose. I feel the burn if I do 20-25mg, but it's not anywhere near what anyone else describes.

Idk the point of this thread, just an observation I guess. What y'all think?

Allow me to preface this post with the fact that I have zero experience with MDMA. I've done 2cb many times and it's one of my favorite psychs.

I obtained some 2cb and I was gifted some MDMA along with it. The problem is that it's only 50 mg worth. My understanding is that 50 mg is barely a threshold dose. I initially thought of doing a Nexus Flip, but with 50 mg of MDMA, is it even worth trying?

I’m considering trying 2cb, and I have a few questions before I go ahead.

1: I understand it’s a like blend of acid and MDMA. Since I’ve never tried MDMA, but I’ve used acid a few times, could someone describe the experience it gives, especially compared to LSD or shrooms?

2: What would be a good starting dose? I’ve used psychedelics in fairly high amounts (250ug and 2.7g PE), so I can manage a changed state of mind.

3: How long does it last, and how impaired will I be?

4: Are there any other side effects I should be aware of?

Hi, I I took 25 mg 2CB HCL from a very reputable person. I have a whole gram of it as well. I waited out. Took it yesterday, around three hours after my last meal. I definitely felt a little bit and had very light visuals, like I felt stimulated and kind of like LSD a little bit, with some neck tension and jaw tightness. But besides that, it was very, very underwhelming, and I was just wondering if some people feel it less than others. I'm very experienced with psychedelics, so that's why I'm a bit confused about why it was so light. Any opinions? Please let me know.

It’s about to turn midday and i have one last 2cb pill. i want to take it during the day, get some personally stuff done! i haven’t eaten since like 10 last night. I’m used to not eating but before i pop it i just want to make sure that like 12 hours fasting wont have me over a toilet or something 😅😅

I got four pikachu pills labeled “25mgs” but it felt more 15. I took 1 the first night, felt great not strong visually. The next night i took one and resdosed 1 90 mins in.

Reckon to say i’m safe to finish the last and take a month break from psyches?

Hi! I have 1g of 2C-B crystal, and am wondering how much to take with my gf for her first time. I am very experienced with other psychedelics but have only taken 2C-B twice, and she has done mushrooms 3 times and mdma once. We aren't necessarily looking to have sex (unless it feels natural in the moment!), but want to have euphoria, visuals, and listen to some music and dance. Can anyone recommend a dose that wouldn't be too overwhelming for her? She is quite an anxious person (OCD), so i don't want to scare her away from this amazing compound. We are planning to take it orally!
