You can use the r/ResearchChemicals search tab, or [Psychonaut Wiki](psychonautwiki.org/wiki/Main_Page) for dosages and ROA’s. However I would strongly reccomend against ordering any research chemicals without doing any prior research (which based on this post and your post history seems to be the case here).
All substances you mentioned are dosed below the 20 miligram range, and I hope that you have a proper miligram scale or at least a way to prepare a volumetrically dosed solution. Check our r/harmreduction for help on volumetrically dosing and a good scale for start is the Gemini-20 (Amazon link!!!). Yes, it is pricy, but it’s YOUR mental and physical health at stake, so is $40 too much? And no, do not cheap out on a lesser scale, you need a reliable one that can weigh miligrams.
Also, PLEASE DO NOT SMOKE any of these substances as I doubt you ordered a freebase version and fumerate salts (the most likely form that you will recieve these in) aren’t great for you when smoked.
Please be safe and careful, the psychedelics you ordered are not considered “conventional” and they are fairly new on the market with varying reports. Dose threshold amounts to begin with, never redose, and if the first time is not to your liking slowly go up in dosage until you hit your sweet spot. DO NOT take a full dose on your first time! Be patient and rememer all dosages quoted for research chemicals are fully anecdotal! Safe Travels!
