(With bonus: tirz/sema maths, the blackout to comeback timeline, and Tracy being… Tracy.)
This might be one of the favourite interviews I’ve done so far, iconic enough that it deserves a place on Substack. Not just because QSC is a long standing name in this community, but because Tracy is one of the few vendor “faces” who will actually answer questions… and answer them like that.
For anyone new here: Tracy is a man, despite the name and the female profile picture. And yes, that profile picture is a famous Chinese actress, which becomes a surprisingly revealing theme in this interview.
QSC has their fair share of haters but probably just as many fans. Even the fans will admit customer service could benefit from a course. But they’re still here, and so is Tracy, which is why I thought it was worth asking for an interview.
Background; The blackout, the “sign of life,” and the surprise comeback
QSC ran heavy promos through late 2024 and then went dark shortly after the end of year period. Communication stopped. Orders stalled. Refunds paused. Silence followed.
In February 2025, the first real update appeared on Meso RX. Tracy claimed around 70% of their issues were resolved, with 30% remaining before operations could resume. He gave no firm timeline, but insisted they would return. He also said OPSEC and legal reasons prevented him from being active publicly.
Then came the part nobody was expecting: QSC resurfaced again in early August 2025 with a Telegram “Official Comeback Announcement.” Tracy described arrests, seized machinery, and confiscated funds, said they were restarting from scratch, and promised they’d make people whole over time, but that the comeback would begin by selling existing/overseas stock while rebuilding operations.
But with QSC suddenly back in public view, I figured this was the moment to ask for that interview, worst case, I’d get ignored or told to get lost.
Instead, Tracy replied the next day: “Ok will check when I have some time.”
So I sent the questions.
This is a direct Q&A, rewritten for readability, with key lines left intact so readers can hear his tone.
Who is QSC (according to Tracy)?
I started with the simplest question: introduce yourself, introduce the company.
Tracy describes QSC as Qingdao Sigma Chemical Co., Ltd, and claims they were once a major supplier in the grey/black market, including being highly ranked on Alibaba in the period when pharmaceutical listings were still allowed.
He positions QSC as unusually early in “public-facing” sales for a Chinese supplier, and frames the end of 2024 as a turning point.
And yes, his job title is “head of sales.”
Manufacturer, lyophiliser, reseller?
This question is where most vendors start bluffing, because…”in this industry, “manufacturer” is often marketing, but Tracy is very specific
His description of QSC’s role is mixed:
QSC does not “manufacture raws” (he claims manufacturers don’t deal directly with Western buyers)
QSC resells raws.
QSC claims it manufactures HGH and IGF-LR3 powders, and handles brewing steroid oils and pressing tablets.
QSC says it lyophilises peptides after buying peptide raws from factories.
In other words: in Tracy’s telling, QSC is not one neat box. It’s a supply chain role that shifts depending on the product lane.
What caused the legal trouble?
I asked the blunt question everyone wanted answered plainly:
Was this about peptides or steroids?
Tracy answered:
“Sale of steroids. The charges were mainly this… peptides stocks were also confiscated… the steroid team had it harder… peptide staff was released fast.”
That’s the cleanest statement in the interview on what the bust was “about” in his view.
“You raised cash because you knew collapse was coming.”
I fed him one of the most common community theories: the idea that the late 2024 promo intensity wasn’t just seasonal, it was a cash grab ahead of collapse.
Tracy rejects that framing and says late year peak sales are normal, especially heading into Chinese New Year periods, and that if they had known what was coming, they wouldn’t have been hit.
Not sentimental. Just: that theory doesn’t fit my timeline.
Christmas tirz: defence and denial
I asked directly about why Christmas 2024 tirzepatide is still such a stain on QSC’s reputation.
Tracy’s response is two-layered:
First, the quality defence:
“The tirz was good… every batch was tested, +99%… overfilled… if anyone claims otherwise, he can share his tests.”
Then, when asked later about the broader “scandal” framing, he also says:
“What Christmas tirz scandal? I am not aware of any of this.”
So: defence and denial. Same subject, two positions.”
Why disappear, and why say so little?
This is the part where Tracy sounds less like a vendor and more like someone speaking through legal caution.
On the long silence, his position is essentially: public communication isn’t worth the risk until the case is closed, and if he has no real update, posting is pointless.
It’s a worldview where silence is not negligence, it’s strategy. Whether you find that reasonable is, unfortunately, what comment sections were invented for.
Compensation: the hierarchy nobody wants to hear
This is the section that explains why the community stayed split even after the comeback.
People wanted to know: who gets compensated first?
Tracy says compensation decisions are made by the boss, and frames compensation as not possible until the brand is fully running again (production + international shipping) and the case is closed. He also says paying compensation “now” could bankrupt them, and he lists priorities like suppliers/logistics/machinery.
He’s choosing survival logic over customer optics.”
Old stock and degradation anxiety
I asked what everyone else was asking: should buyers worry about old inventory.
Tracy’s answer is consistent with his broader “trust the process” stance: he says old inventory has been sold, including to resellers who tested it, and he argues lyophilised peptides are stable and rarely degrade (except some compounds).
Although Tracy is confident. The warehouse conditions remain somewhat mysterious.
What changed in the market while QSC was gone?
Tracy’s market commentary is actually useful: he says newer demand patterns changed (he name checks retatrutide overtaking tirz in popularity, plus other products rising), he claims competitors test less than QSC used to, and he claims prices dropped more slowly without his aggressive price cutting (tirz “used to drop weekly)
In Tracy’s universe, QSC didn’t just compete, it set the pricing and testing standard.
Shipping risk, enforcement, and why vendors are tightening up
On current challenges, Tracy points to stricter enforcement and more inspection pressure on US lanes, with vendors changing or reducing reship policies.
This is the part where Tracy briefly resembles a standard industry spokesperson.
Servers getting nuked: “Censorship.”
I asked about server nukes and with his being one of the first ones, why it happened to QSC
Tracy’s answer is simple;
“Censorship, as simple as that.”
No long theory. No nuance. Just: that’s the environment.
TikTok and the “no gatekeeping” era
I asked whether we’d see Tracy on TikTok.
Tracy’s answer is basically: visibility accelerates busts, so no, keep it Telegram, keep it low profile.
This is Tracy talking like a man who’s been raided. Old QSC didn’t do “low profile.”
Why QSC is like marmite
Tracy’s explanation for why people either worship QSC or want it banned is basically: he didn’t enter the market quietly, he entered it with a price list that threatened many businesses.
He says HGH kits were commonly $150 to $200, and he came in at $55. Testosterone oil vials, he says, were $30 to $40 / vial and his were $6 / vial. In his telling, the first response was predictable: people assumed cheap meant “shit quality,” said so loudly, and then, inconveniently, some of them tried it and decided they’d been overpaying for years.
He also admits the obvious second effect: prices like that don’t just win customers, they create enemies. He says he threatened a lot of businesses and pushed domestic and international sources out of the market, especially raws. So no, it wasn’t always “welcomed.”
Then there’s the third ingredient: his tone. Tracy openly acknowledges he doesn’t speak the way most vendors speak when someone annoys him, and he doesn’t pretend he’s here to be soothing. His argument is that the market forgives a lot if one thing remains true: he says he tested more, changed pricing and testing standards, and, most importantly, delivered. Which is why, in his framing, the comments get intense: people feel like they’re buying from an asshole… but an asshole who’s “the best in the market.”
Supporters, haters, and Tracy’s PR strategy (none)
He thanks supporters.
He tells haters something crude involving 💩
He says he doesn’t regret being aggressive; dignity comes first.
He also admits that drama brings traffic, and traffic can bring sales.
This is not a man trying to be liked. This is a man trying to win.
“The customer is always right”
This is one of the most quotable answers, and also one of the most “you’re either going to love this or hate it” moments:
He rejects the idea entirely and frames it as surrender that rewards entitlement.
“The customer who pays us is temporarily right until their money is in our account lol. It’s not a philosophy, it’s a surrender. It encourages entitled whining and rewards idiocy. The only thing that’s “always right” is the harsh, unflattering truth that most problems are caused by the person complaining about them”
Promos: the most accidental honesty in the interview
When asked about “last chance / biggest ever” promos, Tracy gives a surprisingly explicit explanation of urgency marketing.
Whereas most vendors deny, Tracy explains.
He frames “last chance” promos as deliberate FOMO engineering, not a mistake, not a misunderstanding, just strategy.
Cap colours and “trust the process”
Tracy dismisses cap colour concerns as time wasting and says he built testing threads (with pictures ) so buyers can verify without interrogating him or his assistants.
In summary Proof is posted. Reassurance is not included.
The first rule of QSC: labels are for cowards
At one point, QSC shipped steroid oils labelled as “Honeysuckle Oil.” Not as a joke. Not as a meme. As the actual label.
Some buyers were amused. Others were alarmed. A few were genuinely nervous, not because they couldn’t recognise what they’d ordered, but because mislabelled packaging raises obvious customs and legal concerns.
So I asked Tracy directly about the labeling chaos and whether that undermined confidence.
His response:
“If they expect me to write steroid names because they are afraid to receive ‘honeysuckle oil’ then they’re idiots, they should stick to creatine.”
In Tracy’s world, labels are optional. Insults are compulsory
The tirz/sema combo: planned, not “oops”
I asked Tracy about the tirzepatide/semaglutide combo, whether it was planned, or whether it began life as an unfortunate moment of “cross-contamination” that later got promoted into a product.
He says it was planned, and explains it using starter dose logic rather than accidental
“0.25 mg is the initial dosage for sema.
5 mg is the initial dosage for tirz.
for same ratio, we get the tirz 60/sema 3 if we want to make a blend.”
So this wasn’t an accident, it was maths. Not “whoops,” more “ratio achieved.”
He adds it didn’t sell well at first, but says it’s now moving fast with daily orders and is close to sold out, which, if nothing else, proves that in the grey market the most powerful ingredient is often a simple story and a clean ratio.
Behind the actress: why Zhang Xinyu?
This section is basically why the post is called Behind the Actress.
Tracy insists the Zhang Xinyu avatar isn’t fandom, it’s logistics. Not “my favourite actress,” more “useful packaging.” He says she doesn’t know (and if she did, lawyers would be involved ), and he jokes that she should be flattered as for a few months she was the unofficial face of a multi million dollar international chemical enterprise and then he’d bill her for the publicity.
This is where the mask stops pretending it isn’t a mask.
Personal quickfire (where the interview becomes a character study)
The quickfire round
For the quickfire questions, I’ve had to tidy a couple of answers slightly for Substack, but they are otherwise minimally altered.
Highlights:
Family persona: “he might add a little water, just so they don’t call the police … JK.”
Theme song: the hum of a server farm at 3am and shipping labels printing for the tenth time
Funniest complaint: buyer panicking after receiving 30 vials because they misunderstood what a kit contains and thought they just ordered 3
Career arc: classic studies → stupid suits career → farm life in the middle of nowhere (with a detour through the grey market).
Real photo profile pic: hard no. Too traceable, too messy, too many opinions.
Products he uses / overrated products: full list given with lots of Ts. He’s definitely a man.
Meso drama: he paints Meso RX as a clown parade crammed into a tiny car, honking their horns about purity and shipping times and then piling out to trip over their own feet.
Spare time: “spare time?” he says it barely exists, but when it does: gym, swimming, cooking.
Who he looks up to: no one, according to him. No mentors, no heroes, just him
It’s rare for a vendor interview to read more like a character profile than a product briefing. This one does.
Final: why buy from you now?
I closed with the obvious question: with so many newer vendors offering cheap prices and cleaner reputations, why should anyone go back to QSC?
Tracy’s answer is a full body rant, and the thesis is consistent: “cheap” doesn’t impress him, it worries him. He frames new vendors as dumpster meal cheap (you might eat it, but don’t complain about the consequences), and reframes QSC’s “colourful history” as the point, not the problem: survival is the track record. In his version, longevity isn’t baggage, it’s proof of durability. He also makes it clear he thinks most of the new wave can’t keep up once QSC is fully running again.
And when I ask the question people keep whispering, are you even the real Tracy? he ends it with the most Tracy shrug imaginable:
“ofc it’s same.”
Closing
A genuine thanks to Tracy for giving up his time and answering everything in full “Tracy mode”: sharp, provocative, occasionally funny, and completely uninterested in sounding normal.
Love him or hate him, people will have opinions after reading this, and that’s exactly why this interview belongs on Substack.
And yes: the actress still doesn’t know.
