I was on mobile. I just re-checked. No citations show on the page I'm looking at
https://examine.com/nutrition/do-you-need-to-cycle-creatine/.
Apologies, [on desktop now] the entire visible prose section of the page has no citations _visible_. The weird expanding section hides all the citation links and somehow _I_ missed the references at the bottom of the mile long page because scrolling down and following links showed no references, and the pages linked showed no references.
Once you come to the second call to action button "send me the fact sheet" that wants an email address, I gave up looking for source-cited material (having already gone through a few links).
https://ibb.co/jRYBRQD -- circle the references on that one for me?
You say ~"not selling anything" but the page above has a call to action button to get the info which links to this:
https://ibb.co/RT4F87H
Which is a massively long call to action page -- which also isn't the supplement guide with the creatine citations that one might have expected when following the FAQ link -- trying to sell me a pile of reports for $150 (which is fine, but again if I got there from a google search I wouldn't ever go back to your site looking for similar info).
FWIW I've never been to the site before, have absolutely nothing against it, was on mobile (with standard plugins, ublock) and just called it as I saw it as a user coming to your site fresh with no preconception other than that seemingly half the people here felt it was junk and half the people felt it was the best thing since sliced bread (ie really good).
>literally has 7 references right at the bottom //
My opinion from a UX perspective: Your page structure needs changing, you have the vitally supporting info that gives credence to the info buried below the "other junk" parts that signal the end of the pages relevant content. You'd probably do well to break down the page completely, shorten the summary info and provide banner links to pages with un-collapsed content. The short summary page would include some primary citations in a highly visible manner (the first lines of the content having superscript links) OR would have have links to a full -- default visible -- page with highly prominent citations.
The other way to go would be to flag right up front "this bit has no citation links in" by providing an index to the page content -- the pages are super-long --right below the info box. This is the page structure:
* non-cited summary
* get a fact sheet (requires email)
* Things to Know & Note: links to other pages
* Cautionary notices
* Use notices
* get the same fact sheet (requires email)
* FAQ (citations on some linked pages)
* Human Effect Matrix (citations linked in titles of study names in the modals <-- not at all obvious to me fwiw)
* Scientific Research on Creatine (this is the actual detailed info -- the page that was promised -- but it's all hidden [on mobile] for some reason).
Unless you're on hand to point out everyone's mistakes ;o) ... maybe it's just me that missed the good content, but I think your structure is at least in part to blame, YMMV of course (my email is in my profile if it's helpful). Perhaps you've looked at the site so long it all seems obvious and natural to you; that happens to me when making much simpler sites.
HTH.
