Affiliate Disclosure
Last updated: April 17, 2026
The short version
Mycology at Home participates in affiliate advertising programs. This means that when you click on certain links on this site and make a purchase, I may earn a small commission at no additional cost to you.
I disclose this publicly on this page, and I am required by federal regulations (specifically the Federal Trade Commission’s endorsement guides, 16 CFR Part 255) to disclose it. More importantly, you deserve to know, because it affects how you should evaluate what I write.
Where affiliate links appear on this site
I keep affiliate links deliberately limited. They appear in specific contexts only, and never in places where they would compromise the editorial analysis.
Affiliate links may appear in:
- Product reviews and comparisons, where the entire purpose of the post is to help you evaluate specific products against each other or against the market.
- Posts that recommend specific cultivation equipment I use in my own setup (grow bags, fruiting chambers, pressure cookers, and similar gear), where I am recommending the product based on direct personal experience.
- Posts that recommend specific supplement products that have cleared my five-step evaluation framework, which is published on this site so you can see the criteria and apply them yourself.
Affiliate links do not appear in:
- Educational posts in the Consumer Guide that explain how to read labels, evaluate certificates of analysis, understand beta-glucans, or distinguish fruiting body from mycelium-on-grain. These posts need to stay independent of any incentive for you to click.
- Science cluster posts covering fungal biology, mycology fundamentals, mold, slime molds, and related topics.
- General cultivation guides where the purpose is to teach a technique rather than recommend a specific product.
If a post contains affiliate links, I will disclose that at the top of the post, in plain language, before the content begins. You should not have to hunt for the disclosure.
The five-step framework
When I do recommend a supplement product with an affiliate link, that product has passed a published evaluation framework covering:
- Fruiting body source versus mycelium-on-grain
- Extraction method and standardization
- Third-party certificate of analysis availability
- Beta-glucan content measured by an appropriate assay
- Transparency in sourcing, manufacturing, and labeling
A product that fails any step does not get recommended regardless of whether the brand offers an affiliate program. A product that passes may get recommended whether or not an affiliate program exists. The framework gates the recommendation. The affiliate program has no influence on it.
Affiliate programs I currently participate in
At the time of this update, Mycology at Home participates in the following affiliate programs:
Amazon Associates Program. I am a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, I earn from qualifying purchases.
I may join additional affiliate programs in the future, including those run directly by supplement brands, cultivation suppliers, or retailers I use personally. When I join a new program, this page will be updated to reflect it. You can always check this page for the current list.
How affiliate commissions affect you
Clicking an affiliate link and making a purchase does not change the price you pay. The commission I receive comes out of the retailer’s marketing budget, not out of your wallet.
Clicking an affiliate link also does not obligate you to buy. You are free to use the link for information and then purchase elsewhere if you prefer. You are free to close the link and search the product name independently. The decision is entirely yours, and I would rather you buy the right thing for your situation than buy anything at all through my link.
If you would prefer not to use any affiliate links on this site for any reason, you can simply search the product name on Amazon or the retailer directly. I lose the commission. You get the same product at the same price. No hard feelings.
Sponsored content
At the time of this update, Mycology at Home has not published any sponsored content.
I may accept sponsorships in the future if the brand, the product, and the context fit the editorial standards of this site. If I do, any sponsored post will be labeled as sponsored at the top of the post, in plain language, before the content begins. A sponsored post will include the same level of editorial scrutiny as any other post, including negative findings where warranted. Sponsorship pays for the post to exist. It does not buy the conclusion.
If a sponsor ever requests that I soften a negative finding, omit a flaw, or change a conclusion, I will either publish the post as originally written or decline the sponsorship entirely. That is the line.
Free products, review copies, and gifted items
At the time of this update, Mycology at Home has not accepted any free products, review samples, or gifted items in exchange for coverage.
If I ever do accept a review sample for a product review post, the post will disclose that clearly at the top, the same way sponsored content is disclosed. Receiving a review copy does not obligate a positive review. Products that fail evaluation get a negative review regardless of how they arrived at my door.
Why this disclosure exists
Short answer: the law requires it, and it is the right thing to do.
Longer answer: the mushroom supplement industry is full of affiliate-compromised content dressed up as objective analysis. Review sites that appear independent are often owned by supplement brands. “Best of” lists frequently rank products in the order of commission rates rather than product quality. Consumers get misled, often without realizing it, because the financial relationships are hidden.
I believe transparency is the only honest way to run a site that covers products. You deserve to know when I have a financial stake in a recommendation. You deserve to know when I do not. And you deserve to know the exact rules that govern when affiliate links appear on this site.
That is what this page is for.
Questions and corrections
If you find an affiliate link on this site that is not properly disclosed, that appears in a post where it should not, or that seems inconsistent with the standards stated on this page, please let me know. I will correct it.
