2c-ef (28 mgs) - 2c-ef you up

I tried 28 mgs of 2c-ef recently, which had been lab tested and verified, and...wow! What a powerful substance!

I decided on 28 mgs based off of reports and comparsons to 2c-e. However, 28 mgs hit me harder than 28 mgs of 2c-e, which was surprising considering all the literature that states it's slightly weaker pound for pound. The come-up was a bit rough, more than other phens for me, and I don't usually get any nausea. Thankfully, it was just a rough 15 minutes or so, and then it was smooth after that.

A couple thoughts, since I'm not good at taking notes during a trip:
- It left me with a stimmy, but tired feeling. I didn't want to move, mostly just laid around. But it was very euphoric. Just lying down and meditating and listening to music was pure bliss.
- It's very shaky. Moreso than other psychs. My legs often felt like they were vibrating. I think that's due to the high dose. Next time, I'll try around 20-25 mgs and see if that mitigates the shakiness and the rough come-up.
- This substance has legs. Lasted around 12 hours. I was super tired the day after, but the afterglow is fantastic.
- Great body euphoria and visuals, though 2c-b and 2c-e are much more visual.
- Music sounded incredible and I swore my hearing became so much more sensitive.

All in all, a wonderful drug. Still not as good as my favorite, 2c-e, but a worthwhile substance that offers a lot. Just be prepared and have a good 12 hours free.

EDIT: Please note that my dose is higher than the recommended. I'm a natural hardhead when it comes to psychs. I have no desire to brag about eating heroic doses, as I'd rather be the opposite and save myself some money and conserve substances.

Just a follow-up on this: a few weeks later, I tried insufflating about 12-13 mgs of 2c-ef. To me, this is the way to go with this substance. I didn't get the body shakes/jitters that I experienced taking 28 orally. (Admittedly, I probably took a few mgs too many. Next time, I'll try out 23-25 mgs.) The duration was also shortened to about an 8-10 hour total trip, as opposed to the 12-14 if taken orally. The overall experience was still similar. Great bodyfeel, not as visual as 2c-b or 2c-e for me, but it's also probably the most erotic 2c I've taken of them all so far.
 
That -F is going to slow down metabolism some. Is it significantly different to, say, 2-(2,5-dimethoxy-4-propylphenyl)ethan-1-amine (2-CP).

The ecquisite insights made by Dr. Shulgin are still astounding. When he made examples which were incredibly complex and low-yielding just to understand. Whenever anyone points out how easy the chemistry is, I pull the 2C-T-13 work and point out that given the number of steps, only a skilled chemist would get ANY product.

But great report - much appreciated.

How much did it hurt to snort it?

Did you feel it instantly?

I agree that oral doesn't seem to be the best ROA for this.
I really wanna try rectal, snorting does swem interesting, too.

I might not be the best person to ask about this. I don't mind insufflating 2cs. The feeling to me is akin to shichuan peppercorns, minus the extreme numbing. 2c-ef was much easier to take than 2c-e. Like other insufflated 2cs, I was coming up within minutes and fully tripping within 15-20 minutes. The burn was much less than I was expecting, but that could be due to only insufflating around 12 mgs. Meanwhile, snorting 30 mgs of 2c-e was a dysphoric blast that left me wrecked for the first half hour. Things were lovely after that, but it was way too intense. 2c-ef, at that dosage is perfect.

I've yet to try 2c-p. So far, I've only experienced 2c-b, 2c-e, 2c-ef, 2c-i, and 2c-t-2. Of all those 2cs, it was most similar to 2c-e, but a bit more gentler, longer lasting, and less visual to me.
 
I haven't kept track of them all only the really good ones and really bad ones stand out.

But what I have noted is an interesting unknown.

2CN was considered to be 'psychedelic tofu' and if memory serves, Shulgin simply says 'well, if 2CB didn't exist... maybe, but it does so 2CN isn't so useful' or words to that effect.

But what he singularly failed to do was note that DON appeared to demonstrate significant differences to, say, DOB and yet he never resolved the two enantiomers of DON. My theory is that one enantiomer is a potent 5HT2a ligand but the other, less active one MAY be a monoamine reuptake inhibitor more in the MDA arena. Purely a conjecture on my part but I could never understand why he presumed that the raecemates would more or less have the character of the (much) more potent enantiomeer.

Same with TihKAL. In that case, it turns out he totally missed (R) 7,a-DMT which is much more like MDA than a psychedelic. But a totally accept that it is niche although the 1960s Upjohn patents don't resolve the enantiomers although it's possible that they gave up before reaching the point where resolution was worth the work.

It's easy to say 'well, it doesn't anser MY niche example' and complain, rather than accept just how much Shulgin's vast body of work HAS given us. I never met the man. He did do a few lectures but it was aimed at people less technical and frankly, the prices were silly. I could have afforded it, but even IF I got to ask a question, it would only be the answer to that question that would be of value to me. Guy was elderly and ill, I sent money but I didn't want the guy to NEED to go out to make money to pay his medical bills...
