Weighted result 8.5/10; owner-set rating 8.5/10.
Direct answer
Optima Supply retains an owner-set 8.5/10 rating. Its retained 75-record certificate archive includes Janoshik, Chromate and ILS evidence with 21 exact listing controls. Opti-(T) identity is printed on retained laboratory documents, replacing a naming-pattern inference. Testing breadth depends on the specific panel and lot. The August 3 Trustpilot observation remains 4.7/5 from 233 reviews as retained history; the profile has since been removed, checked October 3.
Evidence summary
Optima has substantial named-laboratory evidence with documented sample identity and panel breadth. Its owner-set 8.5/10 rating remains; the retained matching record provides 21 exact compound-and-strength controls.
The August 3 Trustpilot record remains available as historical customer evidence: 4.7/5 from 233 reviews. The profile has since been removed. Read the specific lot report and confirm shipping and claim terms, which were behind the storefront gate during the October 3 check.
Optima Supply at optimasupply.is is a US research-material storefront. Its terms, updated May 6, 2026, identify Optima Chemical Supply Inc. Retained company information lists a Milwaukee address, branded contacts and a wholesale program. On October 3 the storefront and lab-results route presented a researcher-eligibility gate, while the terms remained readable. The retained certificate record supplies the analytical evidence below.
PeptidePrices retains 75 logical archive records grouping multiple document panels and historical files. The August 30 collection recorded 230 document uses and 169 distinct source destinations; these are file/link counts, rather than 169 verified current products. Janoshik, Chromate and ILS documents provide named-laboratory evidence. The retained matching record contains 21 exact compound-and-strength listing controls. An archive entry, a source file and an exact current control are different counts; unmatched strengths receive no borrowed certificate.
Panel breadth varies by report. The retained Opti-(T) 10mg Janoshik packet reports 99.656% purity, endotoxin 2.355 EU/vial and passing TAMC/TYMC results on companion reports. TAMC/TYMC measures microbial counts and is distinct from a USP 71 sterility assay. Other reviewed documents add heavy metals or multi-vial content comparisons. Multi-vial testing describes the submitted samples, rather than every vial in the commercial batch. A separate July 8 ILS Opti-(T) 10mg report gives 99.78% purity and 10.48mg content, 4.8% above nominal; those results remain separate from the March Janoshik lot.
Opti-(T) is documented as GLP-2T by source certificates. Janoshik task 133647 prints Optima Chemical Supply Inc., sample Tirzepatide 10mg, batch OPS-33658 and key IZJ9V3PJKZTC. Companion endotoxin report 122485 prints the same sample and batch. This replaces the earlier inference from the Opti naming pattern. Public storefront labels can remain Opti-(T), while exact compound and strength identify comparable price rows. Other Opti labels retain their own source-supported mappings.
The sampled CagriSema report gives 99.91% purity with 4.58mg Cagrilintide and 4.76mg GLP-1S. Retained Cagrilintide, Melanotan-2 and DSIP examples report 99.931%, 99.455% and 99.856% purity respectively. These are dated sample findings. Report IDs, lots, source documents and panel-specific results support individual matches; the library does not establish a universal all-panels-pass claim.
PeptidePrices recorded the exact-domain Trustpilot profile at 4.7/5 from 233 reviews on August 3, 2026. The retained curated summary describes fast delivery, responsive support and repeat orders. That historical customer record remains part of this review. The profile has since been removed, confirmed on October 3, so the 4.7/233 observation is labeled with its original date. No mature corroborating exact-domain Reddit or forum record was established in the October 3 search. The owner’s 8.5/10 rating remains, with COA 10, reputation 7, transparency 7.5 and operations 8. Retained card/Venmo and Milwaukee disclosures supply practical purchasing information; current shipping and claim terms were behind the storefront gate and should be confirmed before ordering.
This Trustpilot profile has since been removed. The displayed rating and count are the retained historical observation dated 2026-08-03.
