Quite an interesting thread. Problem being how inherently subjective this subject was destined to be from the start. I have a couple experiences that could at least show difference between 1p-lsd, lsd25, and ald52.
First off I started doing lsd as a young teen. Quit after a few hundred doses and resumed in around 98-99 rave scene. My 4th time dropping acid was a blotter called Fly in the Ointment (I believe). It had tie die on one side of the sheet, and the backside each hit had either a heart or an ankh on every other perforated hit. I took one blotter and I tripped so unbelievably hard (for one blotter mind you!) that I am not even sure if it was lsd. The year, however, was 1994 and you were hard pressed to find research chem websites! Actually, you were hard pressed to find internet unless you worked at Cern

. It must have been an obscenely large amount of lsd, but I'm not all that sure how much can fit on one blotter. The acid I used to have in late 90s early 2000s was either Dexter's Lab blotter which was explained to me by my E and A contact (yes I sold at Raves, not for money but for the amazing vibe and tribal like hive mind that acid seems to create in the rave atmosphere) from Duquesne University that the hits were soaked in Amber Crystal Liquid. They were magnificent and had a fast turnover rate, which kept them from going bad. I also received the acid in Liquid Form in sweet breath droppers (those tiny plastic bottles that resemble small visine vials and contain a mint breath freshener with some kind of solvent in it. These were made volumetrically by dissolving a preset weight of Amber Crystal's in each vial. I forget the actual dosage per bottle but if I remember correctly it was 70 drops each drop containing 150ugs of Lsd25. People preferred the liquid at Raves because it was easy to dispense by dropping the desired amount of drops on the consumers tongue as opposed to messing with scissor in the dark with sweaty hands. Plus the blotter paper was evidence enough to put you right in Jail. A tiny sweet breathe container could be thrown on the ground and stomped out before being confiscated by the law. Also you didn't have to worry about Agents buying a ten strip and bringing them to the lab for analysis. Either the consumer was a legit raver and happy customer, or if it was a cop, it was nothing but a cop tripping balls with zero evidence for court. Anyhow
This is leading to an experience I had with four drops of the amber crystal liquid drops (600ug lsd25). I dosed it while at a recovery house in Florida. I lay down in my bed, put on headphones playing the Amen Andrews vs Spac Hand Luke (Luke Vibert) cd. Within twenty minutes the music took on that devious feel, and two things became clear to me.. Luke Vibert was the perfect music for Lsd, and that Lsd was not going to be mistaken for any other chemical. After an hour I felt something touching my spinal chord, and before I could get a chance to be freaked out by the odd sensation, my ego completely dissolved and my visuals were not visuals in the classic sense as eyes to see them were not understood. I didn't know "myself" from a chair in the corner of the room. So let's say in my minds eye, I experienced what appeared to be A Giant Double Helix shooting a myriad of smaller double helix into the aether. There wasn't anything said by the entity but instead it was communicated without words that the entity represented the Creator on the other side of the "veil" doing what He does, creating everything. I don't remember much more but I do remember eventually seeing the numbers on my digital alarm clock bouncing up and down until I could eventually see that six hours had passed by in what seemed to be an experience outside of time space. I then managed to get enough ego gathered to stand up and make it to the bathroom to urinate. I remember as I was walking to the bathroom that I just reached pseudo enlightenment. I came to understand the purpose of meditation and prayer, to dissolve your ego so that you could know God who we are blinded to with our worldly 3rd/4th dimensional fall of Light senses. This experience still lives with me to this day. I didn't have the urge to trip for such a long time after that because I experienced what I used Lsd to experience.
Several years later when I saw 1plsd appear online, and I read the comparison to Lsd25 was almost indistinguishable. Based on this, I ordered 8 150ug pellets of the 1p. I started by taking two to get an idea of what I was dealing with. After about 45 minutes I started to experience all kinds of uncomfortable physical body load. Especially I remember feeling as though my stomach would fill up with gas and leave me with this bloated uncomfortable feeling that left the generic OEVs as something of non interest. I figured that the only way out of the physical discomfort was to go all out and dissolve ego so that I could have a musical peak without dealing with body load... Although I gotta say it had some of the most euphoric tactile sensations I've experienced from psyches that seemed to be in sync with music which was really a big part of the 1p experience. I found drum and bass to fit the ticket for the experience. I ended up taking a total of eight pellets which I calculated to be 1.2grams! Omg what have I just done to myself! Actually I was anticipating an experience so hardcore that I was afraid my mind might have become a dangerous weapon that could poke holes in space time in turn swallowing up existence. Nothing of the sort happened. I remember being up for about six hours with my girlfriend on the back porch laughing hilariously with her about almost everything. She was on about four of the tablets. It was at this point we parted was because I wanted her to get home before peaking. It was at this point that I remember the most fatiguing feeling I've ever experienced mentally. I fumbled around with YouTube on my smart phone trying to find a great set to lay in bed and trip out to. I hit play and woke up hours later. I was sleeping on 1.2 grams of what was supposed to be equivalent to lsd 25! It was nothing like lsd. It felt comparable to a heavy dose of strong 4acomipt or something. But it was most definitely 1p because I was cool with the vendor and his RCs always were tested by a third party and sent with the MSDS. I'm guessing that the body load must have come from biphasic metabolism. I feel that 1p lsd must be inactive, having the metabolite as the active chem. I believe this put a heavy hepatoxic load on my liver. This felt nothing reminiscent of true Lsd. Not only this but I feel that the difference in moeity was another factor in its difference from Lsd.
Recently I took 200ug of Ald52 which felt much much closer to clean lsd than 1p. 1p had very little musical feelings to it. I'd venture as far as to say that the evil SOB of lysergics, LSA was closer in character to Lsd than 1p was. An I absolutely was miserable on LSA. However at least LSA seemed to leave me with that feeling of mystic experience that was completely lacking from 1p. Ald52 was very close to Lsd although not as intense. I'm sure that if taken enough of, it would be almost indistinguishable from Lsd.
Are we even sure if the neuropharm of 1p?
Is it a seratonin partial agonist? Or does it work in some way completely foreign to the other lysergics acids? Eww that gassy body load was so uncomfortable and distracting!
At the moment, I'm faced with the decision of buying 200ug of Ald52 or 300ug of AL Lad. I've never had allad. Which one would you guys recommend and why? Considering how I feel about Lsd (imo the best of psychedelic experience, well next to lsd/mdma or candy flipping.. Amazing!). Considering how I am not a fan of 1p, and considering how LSA was an all out pissing nightmare to me. But I still think it was better than lame ass 1p. I'm sorry for the long write up. But, I figured with all of the subjective matter that some real experience can do well for others in the future.
