Brevity, you owe my a new pair of pants because I just shit myself reading your recipe.
OP, the starting materials you will need are not in realm of procurement for the average kitchen chemist. The average kitchen chemist wouldn't have a clue how to set up lab environment were he lucky enough to secure the starting materials and glassware. Shep may know a relatively easy synthesis; but it still will not be easy.
Ten years ago SWIM (old habits), that also happens to hold degrees in biochemistry and unrelated doctorates decided to use his lab skills to manufacture MDMA. Synthesis of MDMA is about 1000x easier to perform than LSD synthesis. The safrole needed is difficult to obtain, however it is 1000x easier to get than your LSD precursors. Synthesis of MDMA required sleep deprivation, temperature switching/holding (ice to heat transfers to maintain temp), stirring, refluxing, distilling, chilling, etc...and days of not leaving the house and not having visitors. SWIM sold all the glassware and vowed never to attempt anything so stressful after this single successful attempt at a complex organic synthesis. If SWIM worked in a lab environment or had a proper work environment he might change his mind
SWIM has isolated/cloned/ and transcribed DNA from a mammalian pancreas. He would categorize procuring the proper precursors, setting up the lab, and manufacturing LSD as considerably more difficult than the aforementioned cloning if done in your home. Hell even if you had a nice lab, it's still pretty damn difficult. Even well practiced LSD chemist are hesitant to risk too much starting material on a single synthesis because so much can go wrong.
SWIM (who is this guy) has read and understands most of the common synths for LSD. He is more than confident that he would NOT be able to pull off a successful LSD synthesis even if he was lucky enough to find the starting materials and proper lab without an experienced teacher. All this said, with the power of human drive, devotion, intelligence, and knowledge you can do anything. If there is one compound I miss that I wish was readily available, that I rarely find it is LSD. There needs to be more of this around. You are so right about that OP.
You want to know why these things are happening and why in the end you receive this chemical known as Lysergic Acid Diethylamide.
