GGPeps (GYC) tirzepatide — anyone have experience?

Not to rain on the parade but four months is a short track record. I've been in the grey market peptide space for years and vendor quality can drift. The 98.6% to 99.1% variance is within normal range but I'd want to see 12+ months of testing data before I'd call anyone "consistent." That said, the pricing is competitive and the fact that you've had five successful deliveries without seizure or loss is meaningful. What's their reship policy if something does get snagged?

Fair point about the timeframe. I'd counter that the community has been testing WWB for longer than just my personal orders — there are Janoshik results going back to mid-2025 on the spreadsheet, and they've been consistently in the 97-99% range across multiple independent buyers. Reship policy: they offer a free reship if your package is seized and you provide the customs letter. I haven't needed to use it personally. They ask that you don't use a PO box and that the address matches a residential location. Standard stuff.

Just placed my second order with WWB last week based partly on this thread. First order was 5x tirz 30mg in January — arrived in 15 days, tested at 98.3% via Janoshik. Consistent with what you're seeing. The cakes were dense, white, no collapse. My only gripe: communication lag. It took them about 14 hours to respond to my first inquiry on Telegram. Once the conversation was going though, replies came within a couple hours during their business hours (remember, Wuhan is UTC+8).

14 hours for first response is actually pretty normal for Chinese vendors. I've waited 48 hours with some other suppliers. Once you're an established customer with WWB the response times drop — my rep now usually answers within 4-6 hours. — what's the deal with payment methods? BTC only or do they take other options?

They accept BTC, USDT (TRC-20), and bank wire (but the wire has a $30 fee so not worth it for smaller orders). I've only used BTC. They send a fresh wallet address for each transaction. Payment confirmation usually comes within an hour of the transaction hitting the blockchain. No PayPal, no Zelle — which honestly I prefer since those leave a more traceable paper trail.
