I ordered a kit of Mast P and the label says this is Tren H?? Is that possible?

Anyone else receive Mast P that can compare cap colors? View attachment 343254

If you go digging deep into the thread history you’ll see that for a time they were printing labels with “Tren H” for everything. Tracy said it was part of their stealth packaging.

…no, it doesn’t make sense. But that’s what happened.

Anyway. He said they stopped doing that, but there was still stock in the pipeline.

They should contain what the product code indicates, and not “Tren H”.

My second order came in today. Ordered last week and recieved today. I hope the peps get cheaper. Would love to have some vintage Adipotide.

Bruh, He could be correct if he is using the wrong filter.
For Reta (or any GLP-1 for that matter) NEVER USE PVDF filters. Nylon is also dodgy. Stick to PES or PTFE. Cellulose acetate is best if you want to be extra!
But when you use hydrophobic filters for GLP-1s, the membrane will bind some of the peptides. Nothing to do with the physics of pore size but rather the electrochemistry of amphipathic peptide molecules.
PVDF be like

I work in the pharmaceutical industry with Peptides. And we exclusively use *HYDROPHILIC* PVDF Filters because it binds the least amount... If anybody is searching for filters I would use one of these but be carefully to use a HydroPHILIC and not HydroPHOBIC PVDF filter because they are actually shit.
We also did our own research on which filters are the best for Proteins and Peptides but here is an external reference: https://www.merckmillipore.com/AT/d...rties-of-Filters/596b.qB.Hj0AAAFM5FB88eJw,nav

well, to be honest I kinda want out of everything, I'm so tired of it all.
Anyway. If I get any I don't plan on taking it long and not in mass quantities that that one dude did who died of unrelated issues.

Once gear seriously damages a person's kidneys they need to throw in the towel. There are studies where with the cessation of AAS use the kidneys go back to proper function only to fail again when they pick them back up. In the last while, dude was still looking swole and I'm pretty sure wasn't taking a doctor's advice when he said he would "heal himself with peptides"...Live large, die large ; leave a giant coffin.

So they aren’t back by reading their latest update.
The raws are old. (No new stock)
Prices are higher (double) than other vendors whom still are able to get raws!
These prices have to be tailored made just for this board and the lack of raws available on this board alone lol

I have in the past. I know I probably should but I haven't the last few vials. Probably 100+ vials went through between people I know + myself. Never had an issue.

Thanks for the feedback mate, I will probably filter it too for the sake of it, but it's good to know that even people who haven't filtered it didn't have problems. I am just worried about the "immunogenicity" stuff people keep talking around here, but really don't have the knowledge to know how serious is it really.

 

[BrunoES]

Not Tirz, but I’ve never filtered their GH and no issues. Lab work came back with good numbers indicating it’s still good after being in my fridge for almost a year now.

Jesus, 1 year? Reconstituted? That's rough! And it didn't even get cloudy or anything? Can't imagine a peptide lasting that long. Nuts.

When someone says they don't have any issues. ask what "issues" they expect.

You can drink water with high lead or benzene content for decades without "issues".

You can inhale radon or asbestos for decades without "issues".

People who think in terms of "I injected it and didn't end up in the emergency room so filtering isn't needed" are essentially telling you to trust that Chinese criminals are prioritizing your health and safety in the way they make drugs in their underground labs.

But you do you. What's the worst that can happen? What could possibly accumulate in your body that could damage your long term health over the course of hundreds or thousands of injections?

This is the telegram update from today for anyone who doesn't use it:

"Hello everyone,

Attached is the current price list. I’ve also compiled answers to the most frequent questions here to keep everyone informed.

1. Stock Availability
Many were wondering why we still have a such items while everyone is out. Due to the annual CNY shipping halt last year, we prepared significant stocks of everything in advance in end 2024. And we got busted straight before those holidays. Our US warehouses remained well-supplied with the unsold raw materials, oils, and peptides from pre-holiday production. This is why we still have inventory when others are running dry.

Some items are indeed getting low stocks: Primo 100 is very low (likely sold out this week), same for test C oil. Primo 200 for example is still available.

2. Cap Colors & SKU Identification (The Simple Solution)
Cap colors are irrelevant. We have never tracked them. Every product is identified by a unique SKU printed under the barcode on its packaging.

Oils: SKU is on the cardboard box (e.g., B014D7 for Mast P, B002T2 for Test C).

Peptides: SKU is on the bubble mailer. It may be under the shipping label, but it's there. (e.g. A066TRBT-40 for tirz 40mg)

Please use the SKU for identification. Don’t open everything and then ask how to tell them apart—the SKU is your answer.

3. Peptide Quality & COAs (The Facts)
All batches were tested. If a cap color doesn’t match your expectation, the (COA) still exists. You can find it by cross-referencing with past price lists or the HPLC thread on Meso. I trust your detective skills.
Regarding storage: The peptides were and still stored on shelves. Scientific evidence on long-term storage of freeze-dried peptides shows minimal to no degradation. Their quality is not compromised.

4. The "Honeysuckle Oil" Label Confusion (Our Mistake)
This was an unfortunate old warehouse stupid labeling decision. A "Honeysuckle Oil Tren-H" sticker was applied to various oils (Test C, Deca, Mast, etc.). We do not label the vials themselves, only the external packaging with its SKU. Please ignore the sticker and refer to the official SKU on the box or mailer.

5. Customer Service & Tracking Numbers (Managing Expectations)
Our operational capacity is limited. I am assisted by one colleague who manages tracking numbers, and her availability fluctuates due to health reasons. Therefore, tracking numbers are typically sent within 1-7 days of payment, sometimes more.
Sometimes, orders ship without a tracking number being given to the buyer. If you haven’t received one, it does not mean your order hasn’t shipped. Many clients receive packages without prior tracking. To avoid confusion, please confirm your order’s SKUs with me after delivery. We are prioritizing getting your orders out the door over administrative speed.

6. Multiple Tracking Numbers & "Missing" Items
With inventory spread across four US warehouses for OPSEC reasons, a single order may ship in multiple packages. You might receive up to four tracking numbers. Tablets may be with raws, some peptides with oils—it’s organized for security, not aesthetics. Your order is almost certainly not missing; it’s just traveling from different locations.

7. International Clients (An Apology and a Promise)
We sincerely apologize to our international clients. Until our legal situation is fully resolved, we cannot resume shipping to the UK, Australia, Canada, and others. We cannot offer restocks or new international services at this time.
Thank you for your patience. When we officially return, we will make it up to you. We will restore our full catalog, maintain our rigorous testing, and offer the most competitive prices—because at QSC, we don’t just resell; we source and produce what others can’t. Customer service will be a top priority again.

For now, we are a US-domestic operation selling existing inventory. Our peptide prices remain the most competitive on the market. Our steroid pricing is structured to manage the current high volume sustainably.

Thank you for your business and understanding.

Tracy"

Whats the breakdown of Ripped: Test P/Mast P/Tren A

Well, True,
But I'm just trying to tell people to play safe. Hydrophilic PES and PTFE are typically/ commonly sold as that(hydrophillic) by default. Simple things get simple results. Not trynna get folks to employ mnemonic devices when checking out on Cobetter or alibaba

 

[Middus]

......, and offer the most competitive prices—because at QSC, we don’t just resell; we source and produce what others can’t. Customer service will be a top priority again.

Good for them. However when QSC's desirable is no longer available, the other re-shippers available (stuff) becomes the desirable.

Pretty lengthy post to say what some have theorised since. Some QSC insider got a hold of QSC's US domestic warehouse(s).
I'm not surprised there is no other warehouse available. the last days of QSC was Tracy complaining about Warehouse busts in Europe.
