Adrafinil 300mg Capsules Vs. Bulk Powder

See Full List of Adrafinil Suppliers (Capsule & Powder Vendors)

Most synthetic and natural nootropic compounds are sold in two form; capsules and bulk powder. Adrafinil can be readily found in capsule and powder form at many online stores, but which should you buy?

Each consumer has his/her reasons to use either capsules or powder. The following are some basic points you should keep in mind when deciding which form to purchase adrafinil in.


The standard dose of adrafinil is 300mg, and that is the amount used by most capsule manufacturers. Most users should not need more than 300mg a day, but some do. Depending on varying individual factors, some users need to take a 600mg or a 900mg dose to get noticeable results, which means taking 2 or 3 capsules.

The powder is usually sold in bags of 10g, 20g, 30g, etc. Again, the daily dose should range from 300-900mg, but you will have to use either a micro scoop or a digital scale to measure the amount you want to use.

Ease of Use

The capsules are obviously easier to take since all you have to do is pop one capsule (or more) with a glass of water.

The powder is a little messier to use, but manageable. You can mix it with water (partially soluble) or any other drink of your choice. The taste is slightly bitter but acceptable.


The purity essentially depends on the source of the drug rather than how it is delivered. Some suppliers provide a third-party lab Certificate of Analysis (COA) that shows the purity of the tested sample.

Most powders have a 98%+ purity, and the same applies to capsules. However, some manufacturers add fillers to their capsules. While fillers are harmless, some users may not be comfortable consuming them with every supplement they take. Make sure to read the product label to find out if any fillers/additives are used -- they should be listed under "Other Ingredients".


Price is one of the main points to take into account when comparing capsules and powders. As a general rule, bulk powders cost a little less than capsules.

There are several factors that affect the price, such as quality, purity, customer service, etc. Although the price should be considered when choosing a supplier, it should not be the only basis for your decision.

Importing & Customs

Adrafinil is an unregulated substance in the US, Canada, UK and most other countries. It is not an approved drug, but still it is legal to buy it for personal use without a prescription. That does not apply to France and Australia, where adrafinil is classified as prescription-only.

Although it is not banned, some consumers in Europe and Australia have had their shipments held by customs, so if you live in one of those countries and import adrafinil from another country there is a risk that the package might get held or returned by customs in your country.

Buying large quantities increases the chance of your package getting seized. Also, bulk powder may look more suspicious than capsules.

If the seller is located in another country, it may be safer to buy adrafinil in capsule form and import it together with other natural supplements so it won't draw attention or suspicion. Again, adrafinil is not illegal, it is just not approved as an over-the-counter supplement.

Where to Buy Adrafinil Capsules and Powder?

You can find adrafinil at most supplement retail stores that sell nootropics. Check out the full list of adrafinil suppliers to compare prices at some reliable online stores.

It is not easy to source adrafinil locally. Popular drug/supplement stores like GNC, CVS and Walmart don't sell it, but if you could find it at a local store you will save yourself shipping fees and time.
