Ordering is simple: add boxes, tap My Order (bottom right) to send it, and you receive payment instructions. You never pay on this site. Bulk orders: ask about volume pricing.
How ordering works
- Add boxes to your order (minimum one box per product).
- Tap the My Order button (bottom right), check your boxes, then tap Continue.
- Enter your shipping details and tap Send My Order. You get an order number right away.
- Pay right away: crypto addresses show on the confirmation screen, or for card/PayPal a secure payment link is emailed to you.
- Before shipping, MMK sends you pre-shipment photos and your order number to confirm.
- US orders (Texas and California warehouses) ship within 48 hours by UPS. China orders ship the next day and arrive in 5-8 business days. No weekend shipping: weekend orders ship Monday/Tuesday.
How to pay
Option 1: Crypto (no fee). Send USDC (stablecoin) or BTC directly to the wallet address you receive with your payment instructions.
Option 2: Card, PayPal, Apple Pay or Google Pay (about +9% in fees). MMK emails you a secure Alibaba payment page. It is billed by MMK's payment company, Fuzhou Zhangyu Gen Network Technology Co., Ltd, so that is the name you will see on the invoice. The total includes MMK's 6% card fee plus Alibaba's small processing fee (about 3%).
New to crypto? It takes about 2 minutes:
- Open Cash App, Coinbase or Strike and buy the dollar amount in bitcoin (or USDC in Coinbase).
- Tap Send, paste the wallet address from your payment instructions, and send the exact amount.
- Put your order number in the note if the app allows it.
Shipping
- 🇺🇸 US warehouses (Texas + California): ships within 48 hours by UPS. $40 for 1-5 boxes, $50 for 6-10 boxes, and up from there for larger orders.
- 🇨🇳 China warehouse: ships the next day, estimated delivery 5-8 business days. $70 for 1-5 boxes, $80 for 6-10 boxes. Used when an item is out of stock in the US; MMK confirms with you before shipping from China.
- Ordering from both warehouses? You pay one shipping fee for the whole order.
- No weekend shipping. Orders placed on the weekend ship Monday/Tuesday.
- Before shipping you receive pre-shipment photos and your order number to confirm.
Real photos from the warehouse
No stock photos. These are MMK's own boxes, photographed at the warehouse. Every box holds 10 vials and is labeled with the product code, strength and expiration date. The vials themselves are unlabeled, so keep them in their labeled box.
COA & third-party testing
MMK's products are tested by independent third-party labs (Janoshik and Freedom Diagnostics). Reports cover purity and, where tested, endotoxins.
