Cheap alternatives to Adderall that somewhat work over the counter would be considered either caffeine or nootropics, but taken on their own the results are less than fantastic.
I wouldn’t exactly call the results that you attain a true substitute to very powerful prescription drugs from either caffeine or nootropics, a stronger stack with multiple herbal stimulants is needed get the necessary strength needed. If you consume too much caffeine there is a point where the effects do not increase and the side effects become too much. Taking large doses of nootropics alone also does not give noticeable results either, taking a large dose of nootropics is also not a great idea as these supplements should only be taken around the levels that are recommended as the effects also do not increase once a certain dosage is reached. Taking the right stack of nootropics is also something that can be quite expensive as well as just taking one nootropic is often not enough to get the results that someone will want, even taking an expensive nootropic stack can have results that can be hard to judge.
For this reason I suggest only buying a natural and OTC Adderall alternative that is worth the most money per milligram per pill. The prices for these types of products can range as do the total milligrams and amount of pills per bottle. After checking the total mg’s of a product you then want to see what the serving size as this part of the label often confuses people. To find out how much each pills you simply divide the total number of pills by the price of the bottle. The best mg per pill with the most pills in a bottle for the price is Addrena at about 66 cents a pill as it has 60 pills in a bottle at a price of 39.99 per bottle. If bought separately the supplements in Addrena would be higher priced, a good trick is to check how much each supplement sells from a quick google search of each ingredient in a stack. Based on those numbers while also checking the milligrams you can see how good of a deal you are getting.
The last thing you want to research before buying an Adderall alternative is to make sure that you are purchasing a product that has a money back guarantee, because even if you find a cheap Adderall alternative it doesn’t mean it works so it is obviously a good idea to double check and make sure that you can get your money back after buying it.
