In February, a YouTube video titled “This AI TikTok Shop Video Made Me $67,420 (Here’s How)” detailed how a New Zealand creator named Harry Chang generated revenue from a supplement brand called Rosabella. The video, posted by Chang alongside YouTuber Jimmy Farley, described the production of a marketing clip titled “Nigerian SECRET to CLEAN LIVER!!”.
The production process
Chang admitted to copying a script from a channel named “liverboosthub11” and modifying it to claim the product was a traditional remedy used in Asia or Africa but unknown in America. He used Google’s VEO 3 to generate a Black woman wearing a surgical mask pointing at another AI-generated Black woman in a pink dress standing on a stage.
The foreground figure was instructed to use a strong African American accent and deliver the line: “Why is nobody talking about what this hoe said?! If you’ve got issues with that belly, must watch!”
“Builds curiosity, builds intrigue,” Chang said. “People want to know, ‘damn, what did she say? What did that ho say?'”
To generate the voice, he used ElevenLabs. He selected a preset named “Latisha 1” from a list that included options like “African American Woman Organic” and “Sad Black Woman in Car.” He synced the audio with the video in CapCut. The result gathered 1.3 million views on TikTok and reportedly converted into tens of thousands of dollars in affiliate sales.
In a separate video titled “How I print $51,000/month profit with AI influencers (feels illegal)”, Chang stated he had received Rolexes from clients as payment for selling their products.
A new lawsuit argues this method is illegal. Several YouTube videos mentioned in this report were deleted after 404 Media requested comment.
A legal battle over Rosabella
In February, the supplement company Humann sued Ambrosia Brands. Ambrosia, which operates Rosabella, allegedly directed the creation of hundreds of TikTok Shop videos featuring AI-generated doctors. These figures oversold the benefits of Rosabella’s products.
The lawsuit reveals details about how a group of 20-something YouTubers built this network of AI influencers. Rosabella operates more as a social media hustle than a traditional supplement business. The strategy mirrors spam and get-rich-quick schemes, but here the content targets elderly people with health claims.
Earnings come from product commissions rather than view counts. Rob Freund, a lawyer who spotted the case on X, noted the scale of the operation.
“All these guys are ex-dropshipping guys,” Mallory DeMille, who studies the wellness industry and reported on the topic for the podcast Conspirituality, told 404 Media. “They could have chosen anything to sell to make AI content out of, but they chose supplements, and it’s interesting they chose supplements because it’s such an unregulated market where [they] can basically pump out whatever product they wanted to with very little oversight.”
DeMille added that the marketing side is also unregulated, with human influencers making unfounded claims without consequence. “In terms of ease of making money — wellness, they chose this industry for a reason. I think it’s pretty seamless, has proven to be seamless and now they’ve sold a fuckton because of how easy it is.”
Targeting the elderly
The lawsuit highlights TikTok videos featuring AI-generated doctors and TED Talk-style speakers. These clips are identical to the tutorials Chang has shared. Many more videos promoting Rosabella exist on the platform but are not part of the legal filing.
Chang explained his focus on the “elderly health” niche: “It’s an extremely profitable niche, especially in the U.S., guys.”
“In the U.S., they have very high demand for health products,” he said. “They don’t have any free healthcare, right? People over 35 literally are very concerned about their health […] You have moms who buy 100 supplements and put them all in their cupboard. It is crazy. It’s crazy.”
He noted that generating AI influencers who look older is standard practice for this sector.
“They’re relatable and credible,” he said of three older-looking AI people shown on screen, one shilling beetroot powder. “Why? Because they are old. People are more willing to listen to old people only because they see them as more wise and intelligent […] and look how credible they look. They’re speaking on stage like TED Talk-type style and they’re more relatable because they’re more similar to the age we want to target. If you’re trying to sell health products to a 50-year-old, well, make your avatar 50 years old.”
Fake doctors and false claims
The lawsuit alleges Rosabella used paid influencers and AI characters to make unfounded medical claims. “In several TikTok Posts, the post purports to show a doctor, medical professional, or other medical authority espousing the health benefits of Defendant’s products. All or nearly all of the ‘doctors’ featured in the TikTok Posts are AI-generated and fictitious, making the claims in the advertisement false and/or misleading,” the filing states.
A specific example cited is a June 14, 2025 post by the influencer ‘poormaninla’. The video depicts a doctor in a white coat promoting the product. Before the doctor speaks, a separate speaker in scrubs is imposed on the screen.
The ‘poormaninla’ account remains active on TikTok. Several videos have hundreds of thousands of views. One clip features an AI-generated man in a lab coat stating: “The best food for Black women to eat if they want a slim stomach is not turmeric, it’s not ginger, and it’s definitely not blueberries. Just one teaspoon of this food reduces gut inflammation.”
The lawsuit argues Rosabella is “orchestrating a misinformation campaign on TikTok through its network of influencers,” who make misrepresentations about the health and wellness benefits of the beetroot products that are entirely unfounded.
What it means
Creators can now build entire businesses around generating fake medical authority. The tools allow anyone to produce convincing videos of doctors and experts making specific health claims without needing credentials. The business model relies on the fact that these videos are indistinguishable from human content at first glance, allowing sellers to bypass scrutiny while targeting vulnerable demographics with unverified remedies.
