⚠ Peptide Sciences SHUT DOWN March 6, 2026 — anyone have experience?

I'm absolutely livid right now. I sent my PeptideKingz semaglutide 5mg vial to Janoshik for HPLC testing and the results just came back. ZERO active ingredient detected. Not under-dosed. Not degraded. Literally nothing but mannitol filler in the vial. I've been injecting this garbage for 6 weeks wondering why I wasn't seeing ANY appetite suppression or weight loss. That's $280 down the drain and 6 weeks of my life wasted. Janoshik report #JAN-2026-03881 - Expected: Semaglutide ~5mg - Detected: 0.00mg semaglutide - Detected: Mannitol (bulking agent) - Purity: N/A (no peptide detected) I'm posting the full PDF in the attachments. Everyone who bought from PeptideKingz needs to get their stuff tested IMMEDIATELY. This is straight up fraud.

Holy sh*t Mike. I just ordered from them LAST WEEK. Two vials of sema 10mg and one tirz 15mg. Are you serious right now? They had good reviews on Reddit and their website looked legit with COAs and everything. Did you buy directly from their site or through a reseller?

Unfortunately this doesn't surprise me at all. I flagged PeptideKingz about two months ago in the vendor review thread. Their COAs looked templated — same formatting, same "lab" name that nobody could verify. The batch numbers on the COAs didn't match the vials. if your order hasn't shipped yet, do a chargeback immediately. If it has shipped, send at least one vial to Janoshik or LT before you pin anything.

MOD NOTE: We are adding PeptideKingz to the blacklisted vendor list effective immediately. Multiple reports and now confirmed lab evidence of completely bunk product. If you have purchased from PeptideKingz: 1. DO NOT use any remaining product 2. File a chargeback with your bank/credit card company 3. If you paid with crypto, unfortunately recovery options are limited 4. Consider submitting a report to the FDA's MedWatch program 5. If you experience any adverse effects, contact your healthcare provider We will be updating the blacklist thread shortly. Thank you for the lab work.

I bought from them in January and actually DID have appetite suppression for the first two weeks, then it completely stopped. Now I'm wondering if the first batch was legit and they switched to bunk once they built up enough customers. Classic bait and switch. Already disputed the charge with Chase. They were surprisingly helpful once I explained it was a fraudulent health product.
