Trust Index breakdown

DerivedV3

The Trust Index weighs five evidence pillars — purity claims-vs-reality, testing transparency, enforcement conduct, operational accountability and reputation integrity — into a single 0–100 factor. Nothing here can be bought.

Provisional — Insufficient Data. This listing is under review; the Trust Index is withheld until verification completes. A precise number is withheld rather than guessed — absence of evidence is never shown as a low score.

Prices captured live 2026-06-27 from product pages and the /shop/ catalog (variant low/high ranges shown where a product has multiple sizes). BPC-157 read directly as 5 mg $30 / 10 mg $55, which conflicts with a stale search-snippet figure of '$105–$250' for the same SKU — the live product page is treated as authoritative. Peptides ship as lyophilized vials; bacteriostatic water is sold separately ($30). The Tirzepatide page URL carries a 'peptide-sciences' slug, but the page body does not assert a Peptide Sciences manufacturer relationship — possible reseller/relabel ambiguity, unconfirmed.

Algorithmic trust score 0/100 — 'Caution Recommended'. Negatives: all contact emails on free providers (Gmail), low Tranco traffic ranking, no reviews on popular platforms, reported for phishing and flagged suspicious by IPQS, slow load. Positives: valid Let's Encrypt SSL, active online store, DNSFilter-safe. ScamAdviser also auto-detected card/PayPal/Alipay payment icons, but this is unconfirmed against the live checkout.

Finnrick Analytics—

No Longevity Peptides vendor page exists in Finnrick's index (263 vendors as of 2026-06) — no independent purity tests on record for this brand.

No independent reputation footprint located as of 2026-06-27: no Trustpilot, BBB, Sitejabber, Scam Detector, Finnrick, vialaudit, PepPal, or Reddit/forum coverage was found for longevitypeptides.us. ScamAdviser scores the domain 0/100 ('Caution Recommended', 'might be a scam'), flagging the free-Gmail contact address, very low Tranco traffic, a phishing/suspicious flag from IPQS, and 'no reviews found on popular review platforms'; the only positive signals it lists are a valid Let's Encrypt SSL cert and an active store. Domain registered 2025-03-12, so the absence of community history is consistent with a new operation, not necessarily proof of fraud — but there is zero independent corroboration of any quality claim.

FAQ

CitedV31

Is Longevity Peptides (longevitypeptides.us) legit, and what is on record?

Longevity Peptides is a US-facing research-peptide storefront at longevitypeptides.us. On record: the domain was registered 2025-03-12 (Network Solutions; registrant in Tigard, Oregon), the site discloses no business entity, physical address, or phone, lists a free Gmail address alongside its support email, and has no Trustpilot, BBB, or independent lab (Finnrick) footprint. ScamAdviser scores the site 0/100 ('Caution Recommended') and notes an IPQS phishing flag. It claims third-party HPLC testing and '≥99% COA verified' products but names no lab and publishes no certificates. PeptideCompass computes no vendor score — weigh the cited facts yourself. Research use only.

scamadviser.com

Does Longevity Peptides provide COAs or lab tests?

The site claims independent third-party HPLC testing confirming >99% purity 'across batches' and marks products '≥99% COA verified,' but Certificates of Analysis are offered only 'upon request from verified research institutions' — none are published, no testing laboratory is named, and no batch-lookup/verification tool was found. All purity and COA claims are vendor-stated and unverified. Research use only.

longevitypeptides.us

Where does Longevity Peptides ship from, and how fast?

The Shipping Policy says orders are packed daily around 2:00 PM PST from an 'Arizona facility,' with standard delivery in 3–5 business days plus 2-day and overnight options (overnight cutoff noon PST). No carrier is named and no free-shipping threshold, shipping cost, or international option is stated. Note the location mismatch: the domain registrant is in Oregon while the company ships from and is governed by the laws of Arizona.

longevitypeptides.us

What is the return policy?

Returns must be started within 14 days of delivery, for unused, unopened products in original packaging only (opened/used peptides cannot be returned). The customer pays return shipping unless the error is the vendor's, an RMA is required, and approved refunds go to the original payment method within 7–10 business days. There is no stated reshipment policy for lost or seized packages. Research use only.

longevitypeptides.us

Does it sell GLP-1 drugs, and is that a regulatory risk?

Yes — the catalog lists semaglutide, tirzepatide and retatrutide as 'research' compounds. These are the same GLP-1 drug class that drew FDA warning letters to peer research-peptide vendors in 2024, and tirzepatide is additionally covered by a source-agnostic USITC General Exclusion Order (Eli Lilly) that bars importation of purported-tirzepatide products. No enforcement action against Longevity Peptides itself was found, but the regulatory exposure is noted. Research use only.
