Hi, I’m Luo Gang — your independent “China eye” for sourcing supplements & botanicals.
20+ years inside China’s health-product supply chain, native Chinese speaker, based in China. I’m paid by you, not by any factory — so I tell you what’s really going on, not the sales pitch.
Two decades inside China’s health-product supply chain
I’m Luo Gang. For more than 20 years I’ve worked in China’s health and nutrition industry, and for more than 10 of those years I’ve run my own biotech company — botanical extracts and dietary supplements, from raw material all the way to the finished product.
I’m a native Chinese speaker, based in China, so I see how factories actually operate, day to day. I’ve met every kind of supplier and sales model you can imagine — including the trading companies that approach overseas buyers pretending to be factories.
I don’t own a factory — and I never pretend to be one.
I take no commissions, kickbacks, or hidden rebates from suppliers.
I’m paid by buyers — and only buyers.
That’s the whole reason buyers trust me to sit on your side of the table.

Why buyers get burned sourcing from China
This isn’t about China’s ability to make great products. The real risks live in the process — and most of them show up at the same four points.
Traders posing as factories
You think you’re dealing with a factory — but the goods come from a middleman who can’t control quality or lead time.
Certificates that don’t hold up
COAs and certificates that are outdated, edited, or issued by labs nobody actually audits.
Batches that don’t match the sample
The golden sample was perfect. Then the container arrives — and it isn’t what you approved.
Delays & customs surprises
Missed dates, wrong paperwork, and clearance problems you only find out about when it’s already too late.
Things I wish every buyer knew before ordering
No services to sell you on this page — just lessons from 20+ years on the inside. Full articles and videos are coming soon; here are three to start.
How to read a COA without getting fooled
A certificate of analysis only says what’s on it — and what it quietly leaves out. The three fields I check first.
5 signs your “factory” is really a trader
Most buyers never find out until something goes wrong. The tells are visible from the very first email.
What “GMP” actually guarantees — and what it doesn’t
A GMP badge isn’t a quality promise for your batch. Here’s the difference that matters at customs.

Before you trust a sourcing advisor
Do you represent any factory?
No. I’m an independent advisor paid by the buyer. I work with a broad supplier network through my own company — not as an agent of any factory.
Do you take commissions or kickbacks?
Never. You’re the one who pays me, so my only incentive is your interest. Suppliers pay me nothing.
Why should I trust what you tell me?
Because I’ve spent 20+ years inside this industry and I sit on your side of the table. I’d rather tell you the uncomfortable truth than the smooth pitch — and I show my reasoning, not just my opinion.
What’s your scope?
Dietary supplements and botanical extracts — from raw material to finished product. Not APIs, medical devices, or bulk ordinary food.
