Which do the actual peptide suppliers prefer? Like, if I go to checkout and see crypto payment options, which is more commonly accepted?

In my experience across about a dozen suppliers:

• Bitcoin (on-chain): Accepted by virtually all suppliers that take crypto (95%+)
• Lightning Network: Growing but still maybe 30-40% of crypto-accepting suppliers. Those using BTCPay Server usually support it automatically.
• Monero: Maybe 20-30% of suppliers. More common among international suppliers and those catering to privacy-conscious customers.
• Other crypto (ETH, USDT, USDC, LTC): Variable. Some suppliers accept stablecoins, which avoid the volatility issue entirely.

My recommendation for most people: start with standard Bitcoin (easy, widely accepted, good discount). If you find you value privacy more, explore Lightning (easy upgrade from BTC) or Monero (strongest privacy). Don't overcomplicate your first crypto purchase — get comfortable with the basic flow first, then optimize.

I've settled on using Cake Wallet for Monero when a supplier supports it, and Phoenix Wallet for Lightning when they don't. Between the two, I have almost universal coverage and solid privacy for both. Total setup took about 30 minutes.

The savings from crypto discounts have paid for two extra vials of BPC-157 this year. It literally pays for itself once you're set up. 🤙

Good informational thread. Financial privacy is a legitimate concern, and using cryptocurrency for legal purchases is entirely within your rights. Nothing in this thread promotes illegal activity — peptide research chemicals are legal to purchase in the US.

That said, please be mindful of each platform's terms of service and your jurisdiction's regulations regarding cryptocurrency use.
