CURATED VENDOR PROFILE
Chameleon Peptides
Historical evidence from a former Sacramento research storefront with openly listed vial and kit prices and a dense public Janoshik Analytical certificate trail on the homepage and /testing/ page, including house-code GLP strengths that resolve to named compounds via product-page CAS numbers and lab report labels.
Same formula for every vendor: verifiable testing evidence forms the backbone; third-party reviews adjust it within a bounded range. How scoring works →

On September 30, 2026, the official site displayed a notice announcing permanent closure; that notice did not state a closure date. On October 20, 2026, its public pages redirected to an existing-customer sign-in page saying the store is closed for new purchases; on October 27, 2026, they showed a page saying the store is closed and no longer accepting orders, without the sign-in page. Retained prices are historical and excluded from current Pricing and Stack Builder. Its former storefront sold research-only singles and blends, including house codes GLP-1S / GLP-1T / GLP-1C / GLP-3 for semaglutide, tirzepatide, cagrilintide, and retatrutide, plus Peptide-31 for SS-31 and GLOW / KLOW blends. The preserved certificate archive includes its formerly published Janoshik Analytical links and COA images. Legal entity Origin Sourcing Group LLC publishes a Sacramento, California fulfillment address.
Readers checking historical certificate evidence and house-code mappings from the former storefront.
A permanent-closure notice was observed September 30, 2026; on October 20, 2026 the site said it was closed for new purchases, with sign-in for existing customers only, and on October 27, 2026 it said it was closed and no longer accepting orders. Do not treat retained prices or shipping terms as current offers. GLP-1S / GLP-1T / GLP-1C / GLP-3 are branded names for semaglutide, tirzepatide, cagrilintide, and retatrutide; Peptide-31 is SS-31. Peptide-31 storefront strengths include 35mg while the linked Janoshik/Vanguard reports list SS-31 50mg — match the vial batch before treating those as the same fill. Cold packaging, payment-processor test items, Amino H2O, B12, Lipo-C, and L-Carnitine stay off the peptide $/mg board. No public affiliate program was wired at onboarding.

Checked August 7, 2026Retained Janoshik report and verification evidence
The current archive retains distinct certificate origins from Janoshik Analytical, Vanguard Laboratory, and MZBiolabs alongside a small unidentified-laboratory set. Exact Janoshik test routes account for the independently provider-verifiable evidence; the remaining origins are retained as vendor-hosted COA images without inheriting a provider-verification badge. PB extracts panel-level evidence from each matching record, including HPLC, identity, net content, endotoxin, sterility, and heavy metals only where that result is reported.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
