US Domestic Operation

Important Information

Current Operations & Frequently Asked Questions

Hello everyone,

Attached below are answers to the most frequent questions to keep everyone informed about our current operations.

— Tracy, QSC

1 Stock Availability

Many were wondering why we still have 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.

Low Stock Alert:
  • Primo 100 is very low (likely sold out this week)
  • Test C oil is very low
  • Primo 200 is still available

2 Cap Colors & SKU Identification

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

Example: B014D7 (Mast P) | B002T2 (Test C)

Peptides: SKU is on the bubble mailer

Example: A066TRBT-40 (Tirzepatide 40mg)

Note: May be under the shipping label, but it's there

Important: 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

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

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.

Important: 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

We appreciate your understanding and continued support during this time.
