Direct answer
Is Echo Peptides legit?
Echo Peptides is a registered Rhode Island business. Its testing record is weak for a retailer: all 17 published Janoshik COAs come from suppliers, the newest is from June 2026, and none links a tested lot to Echo’s current inventory.
COA evidenceCOA quality 6/10Public COA data17 complete reports from Janoshik: 13 test identity, purity and content; four blend reports test identity and component content. No extended contaminant panels appear.
Purity: 99.013%–99.974% across 13 reports with numerical purity; none below 98%.
17 supplier COAs; none names Echo Peptides or establishes a match to a current Echo batch.
Echo’s COA library links 21 product entries to 17 distinct Janoshik reports. The reports span June 23, 2025 to June 11, 2026. Four are from June 2026; the other 13 are older. Thirteen report sets include identity, purity and measured content; four blend reports measure component identity and content without reporting purity. Numerical purity ranges from 99.013% to 99.974%, with none of the 13 purity-reporting sets below 98%. No endotoxin, heavy-metal or microbial assay appears in this archive.

Representative laboratory results
The archive provides useful analytical detail. The BPC-157 10 mg report measures 9.72 mg at 99.764% purity; the Cagrilintide report measures 10.13 and 10.18 mg, with purity of 99.913% and 99.907%. The GHK-Cu report separately records the copper and GHK portions instead of presenting both as additional vials. Some product entries reference another strength: the 50 mg GHK-Cu entry uses a 100 mg report, and the 5 mg Semax entry uses a 10 mg report.
03
Wholesale COAs and current stock
The reports are wholesale supplier documentation. Eight name Jujo’s juice bar with TSC as manufacturer, five name ZEN or zen-peptide.com, and four redact the client while naming shpeptide.com as manufacturer. Four reports predate the storefront domain’s February 11, 2026 registration. Echo publishes no test commissioned in its own name and provides no documented match between these tested samples and the batches it currently sells.
04
Company and contact details
The Rhode Island business registry records Echo Peptides LLC, organized February 25, 2026, with a principal-office address of 68 Harrison Avenue, Suite 605, PMB 625120, Boston, Massachusetts. That matches the storefront’s company and contact details. The registry identifies a member-managed LLC and a registered agent; its summary does not name an individual operator. Echo publishes support@echopeptides.co and says research inquiries receive a response within one business day.
05
Reviews
Independent customer feedback for the exact Echo storefront is limited. Peptigrity showed no community reviews in the checked profile. Searches of Trustpilot, Reddit and Peptide Critic did not produce an attributable customer-review set, and the storefront product feed supplies no review ratings. An independent editorial or price-comparison listing is different from a customer’s order experience.
