Frequently Asked Questions
Quality Standards
Are your peptides 3rd party tested? Intrinsic Peptides is committed to quality, transparency, and compliance in every stage of our sourcing and testing process. While peptides are not governed by USP monograph standards for pharmaceuticals, our quality control procedures follow industry best practices and incorporate elements of USP and where applicable. Our Quality Assurance Process Includes: •Independent Third-Party Testing – Every batch is tested for both purity and potency, with a Certificate of Analysis (COA) issued for full verification. •Batch-Level Traceability – Unique batch numbers are assigned and recorded on both the COA and vial labels to ensure complete traceability. •Multiple Sample Verification – Several vials from each batch are tested to confirm consistency and reliability. •cGMP-Compliant Practices – All testing is performed by an independent laboratory, separate from manufacturing, operating under Current Good Manufacturing Practices for strict quality assurance.
Which labs do you use for testing? At Intrinsic Peptides, quality isn’t just a standard — it’s our promise. All products are tested by independent laboratories operating under cGMP (Current Good Manufacturing Practices) and ICH (International Council for Harmonisation) guidelines. While we work with multiple labs to meet specific testing needs, Chromate serves as our primary testing partner. Our Testing Process Includes: Potency Each batch is tested to verify that it contains the precise amount of active ingredient — within 10% of the intended dose — ensuring you receive exactly what’s expected, every time. Sterility We confirm all products are free from bacteria or harmful contaminants, following the same strict safety standards applied in pharmacies nationwide (USP ). Endotoxins In conjunction with sterility testing, this process ensures our products are free from bacterial toxins. All peptides are tested for endotoxins in compliance with USP . pH Balance We verify that our bacteriostatic solution contains 0.9% benzyl alcohol and maintains an optimal, sterile formulation — reducing the risk of irritation or tissue damage.
Is Intrinsic Peptides a 503A or 503B pharmacy? Intrinsic Peptides is not a 503A or 503B pharmacy. We are a research and wellness brand that partners with licensed providers and laboratories to deliver high-quality peptides and related compounds. Our products are not manufactured by or dispensed through traditional compounding pharmacies. Instead, they are intended for clinical research, physician-guided use, or wellness optimization—depending on the context and applicable regulations. Key Differences from Compounding Pharmacies: •Manufacturing & Testing – Unlike compounding pharmacies, which prepare patient-specific medications under 503A guidelines or batch-produce under 503B regulations, our products are manufactured in commercial-grade facilities that follow rigorous quality control protocols. Every batch undergoes HPLC, mass spectrometry, sterility, and endotoxin testing to ensure safety, purity, and consistency. •Intended Use & Labeling – Compounded medications are dispensed directly to patients under a prescription. Our peptides are not prescription medications; they are typically labeled for research or investigational purposes, depending on product category and regulatory requirements. •Regulatory Oversight – Compounding pharmacies are regulated by the FDA and state pharmacy boards, requiring adherence to USP and standards for sterile and non-sterile preparations. Our products are not compounded medications; instead, certain products fall under IRB-reviewed investigational frameworks, ensuring ethical oversight in approved research applications. •Institutional Review Board (IRB) Involvement – Selected investigational products may be used in IRB-approved research settings, enabling structured evaluation under formal clinical protocols. This differs from compounding pharmacies, which operate within patient-specific or office-use dispensing guidelines. We prioritize transparency and product integrity. All peptides undergo independent third-party testing for purity and sterility, with Certificates of Analysis available for verification. For any products requiring prescription fulfillment through a 503A or 503B facility, we collaborate with licensed practitioners and pharmacy partners as needed.
What is IRB-approved research? Intrinsic Peptides are designed for use in IRB-approved research settings, enabling structured evaluation under established clinical protocols. This means you’re working with products that not only meet exceptional quality standards but also contribute to the development of emerging data and valuable clinical insights. Each product is manufactured to rigorous quality and purity specifications suitable for investigational research. While we do not collect data from every clinic, Intrinsic Peptides are utilized in both IRB-approved studies and investigator-initiated research—providing clinics and patients with confidence in the consistency, reliability, and integrity of every batch.
