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.

Thinly Documented. Cited facts on file, but no allowlisted independent assay yet — a precise index is withheld. A precise number is withheld rather than guessed — absence of evidence is never shown as a low score.

Prices captured 2026-06-27 from the vendor site and authorized practitioner retailers (Professional Supplement Center, ePothex, treatlyme/Marty Ross MD) via search snippets — marked unverified. Products are mcg-dosed oral capsules and topical/oral sprays, not injectable vials; price-per-mg is shown only for capsule products where total peptide mass is stated (500 mcg × count) and is a unit-price reference, not a quality score. Sale prices shown where listed; 10% affiliate/newsletter coupons are widely available, which lowers effective price further.

Independent tests tracked

1 on file

GMP / ISO claim

not on record

Vendor states every batch is tested to confirm ≥99% purity and screened for heavy metals, microbials and other common contaminants, and that products are 'third-party tested throughout the entire manufacturing lifecycle' and manufactured in the US under 'FDA-compliant' conditions. Caveat: the company does not publish a public per-batch COA library, does not name its testing laboratory, and editorial reviewers (SeekPeptides, SamaSays) note it does not prominently display independent third-party COAs from community-trusted labs such as Janoshik or Colmaric Analyticals; whether verification is external or internal/contract is unclear from public materials. Positioning is an oral/topical dietary-supplement brand, not an injectable research-chemical vendor.

Methods: Vendor-stated ≥99% purity plus heavy-metal, microbial and contaminant screening; specific assay methods (e.g., HPLC / ICP-MS) and the testing lab are not disclosed. (vendor-stated, unverified).

No independent community-lab tests located

As of 2026-06-27 no Janoshik / Finnrick / vialaudit / Colmaric independent assay of Integrative Peptides products was found. Editorial reviewers note the brand relies on its own ≥99% purity claim and does not surface independent third-party COAs. Because the flagship products are oral/topical supplements (not the injectable vials the community routinely sends for testing), independent purity data is sparse.

FAQ

CitedV31

Is Integrative Peptides legit?

Integrative Peptides is a US oral/topical peptide-supplement brand founded in 2018 by Dr. Kent Holtorf, M.D. (also founder of the Holtorf Medical Group). It sells capsules, sprays and powders — not injectable research-chemical vials — and is carried by reputable practitioner supplement retailers including Natural Healthy Concepts, Professional Supplement Center and ePothex. Scam Detector rates the domain 85/100 ('Authentic'), and a review aggregator reports ~3.9/5. No FDA warning letter against the company was found on record as of 2026-06-27. PeptideCompass computes no vendor score — weigh the cited facts yourself. Research use only.

scam-detector.com

What does Integrative Peptides sell?

Oral peptide capsules, oral/topical sprays and powders — including BPC-157 Pure, KPV, the Gut Feeling blend (BPC-157 + KPV + Immune Peptide A2 + probiotics), Thymogen Alpha-1 and ThyroPep — formulated (acetylated/amidated, delayed-release) for oral and topical absorption rather than injection. Research use only.

integrativepeptides.com

Are the products third-party tested, and are COAs published?

The vendor states each batch is tested to confirm ≥99% purity and screened for heavy metals, microbials and contaminants, with manufacturing in the US. However, it does not publish a public per-batch COA library, does not name its testing lab, and does not surface independent third-party COAs from community-trusted labs (e.g., Janoshik or Colmaric), per editorial reviewers. Treat the purity claim as vendor-stated and unverified. Research use only.

seekpeptides.com

How do payment, shipping and returns work?

Integrative Peptides accepts major credit cards and PayPal (including PayPal Pay Later) — unusual for peptide sellers and consistent with its supplement positioning. It offers free standard shipping to all 50 states (3–5 business days; expedited 1–3) and ships internationally, though it disclaims responsibility for loss/damage in transit. As a high-risk merchant, refunds are subject to inspection and may be issued as store credit only. Research use only.

integrativepeptides.com

What is the regulatory status of oral BPC-157, the flagship product?

BPC-157 is on the FDA's 503A list of bulk drug substances that may present significant safety risks (Category 2) and is treated by the FDA as an unapproved drug rather than a lawful dietary ingredient; USADA prohibits it in sport. This is a compound-level regulatory status that applies industry-wide, not an enforcement action against Integrative Peptides specifically. Research use only.
