Frequently Asked Questions

Clinical Questions
Answered

Common questions from verified practitioners regarding quality, access, compliance, and clinical application.

What purity standards do Longevix peptides meet? +

All Longevix peptides are synthesized via Solid-Phase Peptide Synthesis (SPPS) and tested for ≥98% purity by High-Performance Liquid Chromatography (HPLC). Molecular identity is confirmed via Mass Spectrometry (MS), and injectable products are screened for endotoxins using the Limulus Amebocyte Lysate (LAL) test. Batch-specific Certificates of Analysis (COAs) are available for every SKU.

Who can purchase from Longevix Biosciences? +

Longevix operates exclusively as a practitioner-to-practitioner supplier. Approved buyers include licensed MDs, DOs, NDs, NPs, PAs, and licensed research institutions operating under appropriate IRB or institutional oversight. Retail and consumer sales are strictly prohibited. All accounts require credential verification before activation.

Are your products FDA-approved? +

The majority of our peptide compounds are investigational or research-use compounds not individually FDA-approved for specific indications. However, they are manufactured to cGMP standards and supplied with full quality documentation. Some compounds, such as Tirzepatide and HCG, have FDA-approved commercial analogues; our supply is for compounding and clinical-protocol use by licensed practitioners under applicable regulations. Practitioners are responsible for ensuring their use complies with applicable state and federal law.

How are shipments handled for temperature-sensitive compounds? +

All lyophilized peptides and temperature-sensitive compounds are shipped with validated cold-chain packaging, including phase-change cold packs and insulated carriers rated for 24–48 hour thermal protection. Overnight shipping is standard for all cold-chain products. Temperature logs and shipping confirmations are provided upon dispatch. Receiving protocols are included with every cold-chain order.

What documentation comes with each order? +

Every order ships with: (1) a batch-specific Certificate of Analysis (COA) including HPLC purity data, MS identity confirmation, and LAL endotoxin results; (2) handling and storage instructions; (3) product information documentation. COAs are also accessible digitally through the partner portal and via QR code on product labels.

Do you provide protocol guidance or dosing support? +

Longevix does not prescribe, diagnose, or provide individualized patient treatment guidance. We do offer verified partners access to physician-authored clinical reference documents and dosing frameworks developed by our advisory board. These are educational resources intended for clinician use and do not constitute medical advice. Protocol decisions remain the full clinical responsibility of the prescribing practitioner.

What is your minimum order requirement? +

Minimum order quantities vary by compound and formulation. Verified partners gain access to our full wholesale price list including volume tier pricing. Contact us through the partner inquiry form below for a customized pricing sheet tailored to your clinic's protocol requirements.

How do I verify my credentials and establish an account? +

Complete the Partner Application form on this page. Include your full name, license number, practice type, state of licensure, and clinic or institutional affiliation. Our credentialing team will verify your information against appropriate licensing boards (typically within 1–3 business days) and contact you with account activation details. We may request additional documentation for certain compound categories.
