Okay, well I guess I'll explain myself
First of all, I am no longer a moderator. So not every post I make on Bluelight is going to be "take the lowest dose possible and work your way up".
However, I have pretty vast experience with a lot of psychedelic and other drugs. Many people do ask my advice and I always give the safest advice I am able to give. I can't even begin to count the number of times I've suggested people lower their dose or reconsider a drug combo if they've asked my advice beforehand.
But... I am personally at a stage in my tripping career where I find many psychedelics to be completely worthless.
As for the 2C-D comparison, yes it's not exactly fair to compare 200mg of 2C-D taken over a few hours to 100mg 2C-C taken within about one hour in two split doses.
I had absolutely no problems with that dose of 2C-C. If you read my trip report I compared it in intensity to 3-4 hits of LSD, except found it even milder on my body and easier to handle on my mind. So, if you don't want to trip as hard as 300-400ug of LSD, don't take 100mg 2C-C. Simple as that.
Nor did I recommend this as a starting dose. Try 40-50mg first. Or less, I don't care. This stuff has proven at least to me to be the least toxic and stressful feeling 2C-x I've tried. By far.
However, for those comfortable with a solid +++ trip, I think 70-80mg is a reasonable dose to take. I've read plenty of trip reports where people can't seem to break through to a +++ on 2C-C. Well, you can. You just need more. And it's one of the most beautiful +++ trips I've experienced.
As for the benzo preload... I don't think that's really as much of a factor as you're making it out to be. I take a small dose of diazepam or clonazepam almost every night for insomnia so I know how my body reacts to it, and I know how it affects psychedelics.
Even at 100mg, spread out in 2 doses about an hour apart, 2C-C was completely non-threatening and easy on my body.
So, perhaps I was too enthusiastic about the results right after a great 100mg 2C-C trip. So now I'll just qualify those statements with: "Only experienced trippers should attempt this, and make sure you are comfortable with relatively strong psychedelic experiences."
....
By the way, I plan my next dose to be around 50mg. But I am aware of the magic this chemical holds... even at an entheogenic level which isn't something I can say for 2C-B, 2C-D, 2C-I, or 2C-TFM.
Frankly I don't see how suggesting a 80-100mg dose of 2C-C is any more irresponsible than suggesting a 4-5 gram mushroom trip. Of course mushrooms are proven safe but I've found no evidence in literature or in my own experience that suggests 2C-C has a significant degree of toxicity.
And also, hey, I took 100mg, might as well write a trip report and talk about my experience, right? Nobody else has documented such a high dose so I would be holding back potentially useful info to say nothing at all.
....
I encourage other people to try 2C-C, at a lower dose at first. You'll see the potential. Then if it feels non-toxic, comfortable, and easy to handle for you, take a higher dose next time. It will probably blow your mind.
....
At this point my advice is split into a couple categories: Advice for new users and advice for those who are seeking deep religious experiences from their psychedelic drug use. I think it's pretty easy to tell which is which.
