Integrative Peptides

Company Overview

Integrative Peptides was founded in 2018 by Dr. Kent Holtorf, M.D. (UCLA School of Medicine). Holtorf simultaneously operates the Holtorf Medical Group, a chain of 22+ corporate medical centers. This creates a notable dual role — he owns both a supplement company and a medical practice chain that recommends those products to patients. While not illegal, this is a structural conflict of interest that consumers should be aware of.

Products & Pricing

The product line includes oral capsules and sprays covering a wide range of peptides:

Product	Format	Price	Key Ingredient
BPC-157 Pure	60 capsules	~$150	BPC-157
TB4-Frag	Capsules	~$130	TB-500 fragment
KPV	Capsules	~$120	KPV tripeptide
CerebroPep	Capsules	~$140	Cerebrolysin-related peptide
Thymogen Alpha-1	Capsules	~$130	Thymosin Alpha-1
Bioregulator line	Various	$60–$150	Various short peptide bioregulators

All products are positioned as dietary supplements. Pricing is at the premium end of the oral peptide market.

Transparency Assessment

Score: 40/100 — Significant gaps. The company claims ≥99% purity and third-party testing, but COAs are not publicly displayed on the website and the testing laboratory is not named. For a company selling premium-priced peptides, the absence of publicly verifiable lab reports is a meaningful concern. Consumers must take the company’s word on quality without independent verification.

Testing & Quality

Score: 55/100 — Claims third-party testing but doesn’t provide the verification needed to confirm it. Without named labs, publicly accessible COAs, or batch-specific documentation, the testing claims cannot be independently validated.

Pricing Assessment

Score: 35/100 — Premium pricing ($150 for 60 capsules of BPC-157) in a market where the cost of raw peptide ingredients is estimated at $10–25 per bottle. While markup is expected in supplements, 80%+ gross margins combined with unverified quality claims represent poor consumer value.

Regulatory Standing

No FDA warning letters have been identified. However, legal experts (Holt Law, Frier Levitt) have noted that oral BPC-157 supplements are “just as illegal as the injectable version” — BPC-157 is a synthetic peptide, not a recognized dietary ingredient under DSHEA, and no New Dietary Ingredient Notification (NDIN) has been filed by Integrative Peptides or any other BPC-157 vendor. The FDA has simply not yet chosen to enforce against oral BPC-157 supplement sellers at scale.

Customer Experience

No BBB listing found. No Trustpilot profile. Minimal independent Reddit presence. Most content about the brand comes from the founder’s own marketing channels. One review on Professional Supplement Center reported severe illness within 45 minutes of taking a product (dizziness, vomiting, headache) — a single report, but one that lacks any company response.

Red Flags

1. Founder dual role: Owns both the supplement company and a medical practice chain recommending the products
2. No public COAs: Claims testing but provides no verifiable documentation
3. Testing lab unnamed: Cannot independently verify quality claims
4. Premium pricing without transparency: High prices demand high transparency, which is absent
5. NDI notification gap: Products may not comply with DSHEA requirements
6. Minimal independent reviews: Very little third-party feedback to assess quality

The Bottom Line

Integrative Peptides occupies a concerning middle ground — premium prices and physician branding suggest quality, but the lack of publicly verifiable testing documentation doesn’t support that suggestion. The structural conflict between operating a supplement company and a medical practice that recommends those supplements warrants consumer awareness. Until the company publishes named-lab, batch-specific COAs, the quality claims remain unverifiable.
