High Quality Industrial Grade Glycine From Donghua Jinlong

Published November 10, 2026

A Chinese chemical factory's TikTok ads for industrial grade glycine blew up in early 2024 after the account's AI-voiced product pitches kept appearing on users' For You pages. By late March 2024, parody creators were swapping in AI-cloned voices of podcasters like Dasha Nekrasova and Nick Mullen to narrate fake glycine commercials.

Overview

Donghua Jinlong's TikTok videos read as straight B2B advertising, with a flat AI voiceover walking viewers through the virtues of glycine, an amino acid used in food, pharmaceuticals and industrial chemistry3. The clips are assembled in what looks like CapCut, pairing stock factory footage with product shots while the narrator repeats the brand's full formal name1. The gap between the serious trade-show tone and the casual, meme-heavy TikTok feed is what made the account funny on its own before anyone started remixing it.

Once creators noticed the ads kept showing up on their For You pages, the format became a template2. A typical parody keeps the structure of a factory sales pitch, the mechanical AI voice, and the phrase "high quality industrial grade glycine," then swaps the narrator for an AI clone of a podcast host or celebrity4. The joke works because the original ads already sound like a parody, so very little needs to be changed for the bit to land.

On December 3rd, 2023, the TikTok account @donghuajinlong posted its first promotional video for Shijiazhuang Donghua Jinlong Chemical Industry Co., Ltd., a Chinese manufacturer whose main product is glycine5. The company's own website identifies it as a glycine producer based in Shijiazhuang1. That debut clip picked up roughly 39,600 plays and 1,400 likes over four months5.

The account kept posting similar ads into 2024. A follow-up video on March 12th, 2024 reached about 134,000 plays and 10,400 likes within three weeks, suggesting the algorithm was pushing the uploads to viewers well outside the chemical trade6.

How It Spread

By late March 2024, enough TikTok users were seeing Donghua Jinlong's ads on their feeds that the account became a shared joke. On March 31st, 2024, @gangstasportivik posted a parody using an AI voice of Red Scare podcaster Dasha Nekrasova narrating a Donghua Jinlong-style pitch, gaining over 124,800 plays and 13,500 likes within two days2.

The same creator followed up that day with a second edit, this time using an AI voice of Cum Town podcaster Nick Mullen, which drew around 146,900 plays and 15,200 likes in the same window4. Later on March 31st, 2024, X user @devintoshea tweeted the Nekrasova version with the caption that they'd been getting "tons of tiktoks about industrial glycine for some reason," gathering more than 1,300 likes within three days7. That tweet helped carry the joke from TikTok to Twitter, where readers who had never seen the original ads could get the context3.
