Both are good, and while both are very similar to L, are certainly different in terms of duration, onset, so on. I still have 3 sheets of ALD-52 that were given to me, and I have only taken it a few times, and enjoyed the experiences. Lots of OEVs and CEVs and subtler than LSD in terms of headspace. Since I have easy access to L, I almost always choose it over 1p or ALD, but have them both, as I said. Certainly worth pursuing. I also have access to ETH-LAD as well, and choose to not choose it most often, though I have tried it a few times. ETH has a rough come-up, at least for me, but once you get past that, is an interesting and potent AF compound.
