Frequently Asked Questions

Everything you need to know about Carteum's 3ml vial format, ordering process, shipping within Thailand, quality standards, and compliance requirements.

3ml Vial Format

Each compound is supplied as lyophilized (freeze-dried) powder in a sterile sealed 3ml vial. The powder is sealed under vacuum for maximum stability. To use, simply add bacteriostatic water, gently swirl until dissolved, and withdraw the desired amount per your research protocol. This preserves compound integrity and ensures precise dosing.
Three steps: (1) Remove the flip-off cap and swab the rubber stopper with an alcohol wipe. (2) Add bacteriostatic water using a syringe — direct the stream against the side of the vial, not directly onto the powder. Gently swirl until dissolved. (3) Withdraw the desired dose per your research protocol. Each vial is precisely dosed for straightforward reconstitution.
The vast majority of our catalog is available in sterile 3ml vials. Products marked with the "3ml Vial" badge on our catalog page are vial-ready. A few specialized compounds (such as Cerebrolysin) are available in traditional formats due to their specific formulation requirements.
Unreconstituted vials should be stored at controlled room temperature (15–25°C / 59–77°F) in a dry, dark environment. For extended storage, refrigeration at 2–8°C is recommended. Once reconstituted with bacteriostatic water, store refrigerated at 2–8°C and use within the timeframe specified for each product.

Ordering & Pricing

Browse our product catalog, add your compounds to cart, and proceed to checkout. After you submit your order, we'll send you payment details via email — USDT wallet address (TRC-20 or ERC-20), Thai bank transfer, or PromptPay. Once you send payment and share your transaction proof, we verify and ship.
We keep it simple with two discount tiers:

USDT Payment: 10% off when you pay with USDT (TRC-20 or ERC-20)
6+ vials: 10% off — stock up for a full research cycle

Both discounts stack — pay with USDT and order 6+ vials for 20% off. Free shipping on all orders over $250 USD.
Yes. All USDT payments (TRC-20 or ERC-20) automatically receive 10% off the entire order. This stacks with the 6+ vial volume discount for a maximum of 20% off. The discount is applied automatically at checkout when you select USDT as your payment method.
Yes, free shipping is available on all orders over $250 USD within Thailand. Orders under $250 have two shipping options:

Standard Shipping: ฿100 (~$3 USD) — 1-2 day delivery nationwide
Bangkok Express: ฿150 (~$4.50 USD) — Same-day delivery in Bangkok (order before 12PM ICT)

All orders ship in an insulated protective mailer regardless of order value or shipping method.
We accept three payment methods:

1. USDT (Crypto): Available on TRC-20 (TRON) and ERC-20 (Ethereum) networks. TRC-20 typically has the lowest fees (under $1). After placing your order, you'll receive wallet addresses via email. New to crypto? Visit our How to Buy USDT guide for step-by-step instructions.

2. Thai Bank Transfer: Direct transfer to our Thai bank account. Details provided after order submission.

3. PromptPay: Quick and easy payment via PromptPay QR code. Details provided after order submission.

Note: Third-party USDT providers typically charge a 2–5% service fee on purchases. This fee goes to the provider, not to Carteum.
We offer three payment methods: USDT (crypto stablecoin), Thai Bank Transfer, and PromptPay. USDT is pegged 1:1 to the US dollar with no price volatility. Thai Bank Transfer and PromptPay are available for researchers who prefer local Thai payment methods. All prices are listed in USD.
It's easier than you think. You can buy USDT with a credit card in minutes — no account verification needed for small purchases. We recommend several no-KYC services: Paybis (up to $1,000 no ID), Guardarian (up to ~$150 no ID), Changelly (up to $150 no ID), and Swaps.app (rate comparison, no account needed). See our full How to Buy USDT guide below.

Shipping & Packaging

All products are manufactured in Canada and stocked locally in Thailand. Orders ship domestically within Thailand for 1-2 day delivery.
Every order ships with:

• Insulated protective mailer: Metallic-lined thermal bubble mailer to maintain compound integrity
• Tamper-evident seals: Visible evidence if packaging has been opened during transit
• QR codes: Every vial includes a QR code linking to batch COA, research references, and reconstitution guide
• Discreet exterior: No product names or research-related information visible on the outside of the package
• Color-coded labels: Products are labeled by research category (green for Tissue & Repair, blue for Growth Hormone, purple for Neuropeptide, gold for Cellular & Metabolic, red for Melanocortin Receptor)
Every order ships in a metallic-lined insulated protective mailer. Lyophilized peptides in our sealed vials are stable at controlled room temperature for typical shipping durations. The insulated mailer provides an additional layer of protection for compound integrity.

Quality & Testing

All peptides are HPLC-verified at ≥98% purity. Many compounds test at ≥99%. Purity is documented on the Certificate of Analysis (COA) that ships with every batch. See our About page for more on how we work.
Yes. Every batch ships with a third-party COA documenting purity (HPLC), molecular identity (Mass Spec), endotoxin levels, sterility, appearance, and solubility. COAs are generated by independent analytical laboratories — we do not self-certify. Each COA is batch-specific and included with your order confirmation.
All analytical testing is performed by ISO 17025-accredited or equivalent third-party laboratories. We do not perform in-house testing. Independent verification eliminates conflicts of interest and ensures unbiased, reproducible results.

They are not drugs, foods, cosmetics, or dietary supplements. They are not intended for human or veterinary use, consumption, or therapeutic application.
Carteum sells to individuals and organizations who confirm they are 19 years of age or older and will use the products exclusively for lawful scientific research purposes.

TRC-20 vs ERC-20 — Which Should I Pick?

Both work. Pick whichever has cheaper fees at the time you're sending.

Typical fee Under $1 $1–$10+ (varies)
Speed 1–3 minutes 5–15 minutes
Best when Most of the time Ethereum gas is low

Important: Always make sure you send to the correct network address. Sending TRC-20 USDT to an ERC-20 address (or vice versa) will result in lost funds.
