Affiliate Disclosure

This site uses affiliate links. When you click through and buy something, Off-label Insight earns a small commission at no extra cost to you. That money funds the reading, the lab testing, and the writing you see here. Affiliate relationships do not influence whether a product gets recommended, and they never affect where it ranks when I compare it against alternatives.

What an affiliate link is

An affiliate link is a URL that identifies Off-label Insight as the source of the click. If you click one and buy within a window defined by the merchant, the merchant pays a percentage of the sale to me. The product costs you exactly the same amount as it would if you had typed the URL directly - the merchant absorbs the commission from their own margin, not from your wallet.

Most affiliate links on this site route through offlab.link, a self-hosted link shortener I run so I can track clicks, rotate expired URLs, and replace partners if a program closes. If you're ever unsure where a link goes, hover it and check the destination domain before clicking.

Who I work with

As of 2026, Off-label Insight is an affiliate of:

• Amazon Associates - for books, supplements, and hardware that also happen to be on Amazon. My Associates tag is offlabel09-20.
• ModafinilXL - for modafinil and related wakefulness agents.

This list changes. When I add or drop a relationship, I update it here. I will never hide a relationship in order to keep writing about a product.

How this shapes the reviews

I write the way I would talk to a friend who asked me the same question.

That means:

• Affiliate compensation is never a ranking input. If the best option in a category has no affiliate program, I still recommend it, and I point you at where to buy it.
• I don't accept paid placement, sponsored posts, or free product in exchange for coverage. If a company sends me something unsolicited, I either return it, pay retail, or disclose it at the top of whatever I write about it.
• I have turned down affiliate programs whose products I wouldn't use personally, and I'll keep turning them down.
• Unless I explicitly say otherwise inside an article, every supplement, device, and piece of lab testing I discuss here was paid for with my own money.

What you can do with that

If the writing is useful and you were going to buy one of the products anyway, using the affiliate link is the most direct way to support the work. If you'd rather not, you can search for the product on your own and I'll never know the difference. Either is fine - the content is free either way.

If you think I've recommended something I shouldn't have, tell me. I take that seriously.

Legal and regulatory

This disclosure exists because the United States Federal Trade Commission requires material connections between publishers and merchants to be disclosed under the FTC Endorsement Guides (16 CFR Part 255), and because Amazon's Associates Program Operating Agreement requires it as a condition of my participation. It isn't a legal formality - it's a description of how money and editorial actually work here.
