Ceased operations 27 September 2026. Customer email that evening: Chameleon said it had "decided to end operations" after its underwriting banks received notices from Visa questioning whether sales reached only research customers; the storefront now reads "Permanent closure" with existing-order support at support@chameleonpeptides.com (both read 27 Sep 2026). Scored 10/10 at the time; removed from every live ranking the same day. UPDATE 2 Oct 2026: a farewell email went to customers on the evening of 1 Oct ("As we close Chameleon Peptides … the website will remain accessible to customers with existing accounts"). The storefront is reachable again for account holders, selling remaining inventory at a site-wide 50% reduction with Bitcoin and Zelle as the only payment methods — no card rail, no new accounts. We treat this as the wind-down it says it is, not a reopening: it stays off every ranking.
If you have an open order: keep the order confirmation and card statement, contact the vendor's stated support address first, and if there is no reply within the card network's dispute window, file a chargeback with your bank — a closed merchant's payment processor still has to answer disputes. Do not buy from any site claiming to be Chameleon Peptides "relaunched" or clearing "remaining stock"; successor scams follow every closure in this category.
Where to buy instead: the table below lists every compound Chameleon Peptides sold with the top-ranked active vendor for each, on the same rubric.
Chameleon Peptides scored 10/10 on our rubric at closure; that record stays below, dated, because it was real — but it is no longer a place you can buy. It has been removed from the scoreboard, the price index and every compound ranking. Other closures: vendor closures tracker.
