A customer recently sent our TR30 to an independent lab in Beijing, China.
Here are the results:
HPLC Purity: 99.94%
Peptide Content: 28.76mg
Endotoxin: 0.021 EU/mg
Heavy Metals: <0.05 ppm
As/Cd/Pb/Hg: Not detected
The purity looks great, and the endotoxin and heavy metal numbers are encouraging.
But let's talk about the 28.76mg.
I know some resellers won't be happy seeing 28.76mg instead of 30mg. I get it. If I paid for 30mg, I'd ask questions too.
Here's what I've learned from working with China's peptide supply chain.
First, lab testing isn't always perfect. Sometimes not all the peptide is recovered when preparing a sample. Different labs and testing methods can also give slightly different numbers.
Second, even vials from the same batch won't always test at exactly the same amount. Small differences can happen during filling and production. Conditions can also vary inside a freeze dryer.
But I'm not going to blame the lab or the freeze dryer without evidence. We would need to check the testing method and more vials from the same batch to understand the difference.
The point isn't that every vial must test at exactly 30.00mg. The point is that the differences must be controlled and the product must meet the agreed quality standards.
And remember, 99.94% purity doesn't mean 99.94% of the labeled 30mg content. Those are two different things.
I know resellers have their own customers to answer to. That's why I believe they deserve to see the full results, not just the best-looking number.
This report says 28.76mg. So I'm showing you 28.76mg.
I'd rather explain a real number than hide it behind a beautiful COA.
We talked to the engineers about this issue overnight.
This is the belief I adhere to: people first, products second.
I’ve been quite busy these past couple of days; I attended the second phase of the Canton Fair and, in the section dedicated to holiday gifts, I saw a great many Christmas-themed items.
In the context of China’s import and export trade, peptide substances represent only a tiny fraction.
My Advice for Individual Peptide Users
Individual buyers should buy from local distributors in their own countries. Don't go directly to Chinese suppliers.
Chinese suppliers shouldn't put individual users at risk.
Real distributors know how to find reliable Chinese suppliers. They ask factories how they conduct batch testing instead of just going around asking for COAs.
Meanwhile, some stupid Chinese sales reps are busy stealing COAs from the internet and passing them off as their own. But experienced distributors can tell the difference.
Local distributors have their own brands and online payment systems. They take responsibility for testing the products and providing up-to-date COAs. Shipping is also much faster.
Yes, you pay a little more. But they need to make money too, and they're also taking on inventory risks.
Stop telling everyone to go straight to the so-called "source."
You might think you're getting a better deal, but you could easily end up getting scammed.
Don’t come to me, all you people asking about COAs everywhere—you’re so stupid I don’t even want to reply to you. I see some idiots who pretend to know what they’re talking about, leaving comments everywhere: “COA?” I just think they’re pathetic.
If you can’t even read a COA, you certainly don’t know how to verify authenticity, nor can you tell when it was issued—which means you have absolutely no ability to discern anything.
You’re only good for letting anyone feed you a COA stolen from the internet, just to satisfy that stupid sense of comfort in your head. You won’t listen to the truth at all; you’ll only believe what you see—those stupid eyes of yours.
Nanjing Hanxin Pharmaceutical may be facing a public relations crisis soon, as many people are presenting their raw material Certificates of Appointment (COAs) and claiming to have purchased raw materials from them. I just spoke with Hanxin Pharmaceutical employees to understand the situation.
This isn't a marketing method I invented. I've talked to my distributor clients about raw materials; I'm just stating the facts. However, many Chinese suppliers have seen my approach and are copying it, but they're contradicting the truth.
Hanxin only accepts bank transfers between companies for raw material purchases, and they are tightening this policy and investigating relevant personnel. Otherwise, they will soon face legal threats within China.
I know many distributors who purchase peptides from China have never discussed business with the supplier's owner; it's all done through sales personnel who exaggerate. These sales personnel disregard everything, focusing only on closing deals and earning commissions, showing no respect for the industry.
Today we received a small custom order for 3,000 peptide microneedles, consisting of three products: Reta, GLOW, and BPC-157, with 1,000 pieces of each.
Each piece contains 5 mg of peptide, which is a relatively well-established process at this point. We previously produced a 10 mg TR version, but for this product format, the additional concentration was unnecessary. Customers reported that the results were unsatisfactory. A higher peptide concentration does not necessarily mean a better product. Absorption through these microneedles depends on many factors.
In China, there are no more than five manufacturers that can truly execute this process.
Suppliers who merely sell “price lists” have never even seen this type of product.
Don’t do business with salespeople who only know how to quote prices.
To build a truly long-term business relationship, you need to talk to people who genuinely understand this industry.
People first; product second.
I shipped a box of 100 IU botulinum toxin to a client today. In reality, very few people purchase the XT100 product.
I broke a promise to a longtime customer.
On September 30, the day before China’s National Day holiday, my freight forwarder told me they could catch a flight to the US. I rushed the shipment to Shanghai and told my customer it would leave before the holiday.
Eight days later, it’s still in China. I was furious. I argued with the freight forwarder and, yes, I lost my temper. If they had told me they couldn’t do it, I would never have made that promise.
I can accept delays. What I can’t accept is giving a customer my word and then failing to keep it. So I gave him $100 for the time lost.
He never asked for it. In fact, he stayed relaxed the whole time and even tried to make me feel better. But the promise was mine.
Trust is built slowly — one honest answer, one kept promise, one small surprise at a time.
I don’t like overpromising. I’d rather tell a customer less and deliver more than expected. My reputation is something I’ve built little by little, and I protect it very seriously.
If I can’t do something, I won’t promise it. If I promise it and fail, I take responsibility.
Shipments can be delayed.Accountability shouldn’t be.
Back to work after China’s National Day holiday.Starting the first day with a cup of Chinese rock tea.
In China’s peptide supply chain, products can change and prices can be negotiated.
Experienced resellers look at the person first.Choose the wrong person, and everything after that becomes a cost.Late shipments. Inconsistent quality. No replies when something goes wrong.
Good sourcing doesn’t mean paying more. It means getting the right product, at the right price, from the right person.
Based on data from the Chinese supply chain, the peptide with the highest shipment volume remains—Retatrutide
The current supply chain situation for peptides during holidays in China: Production, warehousing, and logistics are all suspended.
Even during holidays, I need to take two hours to reply to emails and customer inquiries.
The owner of this mountain inn enjoys brewing her own wine; I had a glass of pomegranate wine last night, which was quite good. Her cooking is also excellent; the three of us ate fish and beef.
Current peptide purchase orders will be shipped after October 7th, and will be dispatched sequentially. Therefore, distributors with tight inventory can place orders now to facilitate advance queuing.
On the car ride, I reread *Selected Works of Mao Zedong*.
I took my wife and daughter to a bed-and-breakfast in a small town for a vacation. During this National Day holiday, all the major tourist attractions across China were packed with people, so we chose to get away from the hustle and bustle of the city.
One last logistics problem before China’s National Day holiday.
The Shenzhen route I normally use wasn’t available, so I had to switch this shipment to Shanghai.
It took two days to move from Guangzhou to Shanghai, and today the tracking number finally came through.
This is pretty normal in supply chain work.
Routes change. Schedules change. Holidays make things harder.
The important thing is to keep finding a workable solution and keep everyone updated.
Glad we got this one moving before the 7-day holiday.
For the next three days, all freight forwarding companies were operating at full capacity. If you're not urgently short of inventory, please place your orders after October 7th. Because most of the flight schedules are already full.
Anything that stands the test of time is truly good; time validates everything. Above all, do not rush—stay true to your path, and aim for longevity and health.
Let’s take a look at the authentic Mid-Autumn Festival moon-worshiping customs in rural China.
In ancient times, people would worship the moon after the harvest to pray for blessings. Farmers would offer mooncakes, pomelos, and other crops to the moon. The 15th day of the eighth lunar month falls right in the middle of autumn, which is why it’s called “Mid-Autumn.”
The full moon symbolizes family reunion. Even when loved ones are far apart, they all gaze upon the same moon, which symbolizes completeness and togetherness.
This is the last order processed before the Mid-Autumn Festival.
For the next three days (September 25-27), we can accept order inquiries and confirmations, and report inventory, but we cannot ship orders.
Then, during the National Day holiday, October 1-7, we also cannot ship orders, as freight forwarders across China will be closed for the holiday.
September 25th is China's Mid-Autumn Festival. It is a traditional holiday celebrating the full moon, which symbolizes family reunion.
My daughter is currently using a tablet to learn English, and I really admire her enthusiasm for learning new things. In China, learning English is actually quite challenging due to the lack of an English-speaking environment, and achieving fluency is even harder.
My friends abroad consist solely of the distributors I work with. I’m wondering if I could ask one of them to serve as her online speaking tutor—that would be wonderful.
Previously, a shipment I ordered was detained by UPS in Canada. When I resent it to my customer, I used Canada Post. The shipping cost was lower than UPS, and it still only took 10 days to reach the customer. Not bad.
My customer finds working with me very easy because I focus more on their order status than they do. They don't have to worry about peptide supply at all; they can just concentrate on building their local sales network.
