About Our Products

Where are your products manufactured?

All DrSeinfeld products are made in the USA at a GMP-Certified, SQF Level 2 facility in Florida. We do not outsource to overseas or unverified labs.

Are DrSeinfeld products third-party tested?

Yes. Every batch is third-party tested for identity, potency, and purity. Certificates of analysis are available on request via support@drseinfeld.com.

How should I store my products?

Refrigerate nasal sprays after receipt to maximize peptide stability. Supplements and the Glovera tallow balm should be stored at room temperature, away from direct heat and sunlight.

How do you source ingredients?

We source pharmaceutical-grade peptides and clean, traceable nutraceutical raw materials from vetted U.S. suppliers. No fillers, artificial dyes, or unnecessary excipients.

What is the shelf life of nasal sprays?

When refrigerated, our peptide nasal sprays remain stable for the duration printed on the batch label, typically several months from manufacture. Use by the printed expiration date.

Are your products free of common allergens?

Formulations are designed without unnecessary fillers, artificial dyes, or common irritants. Always review the full ingredient list on each product page and consult your physician if you have specific allergies.

Nasal Sprays

How does intranasal peptide delivery work?

Intranasal sprays deliver peptides across the nasal mucosa directly into systemic circulation, bypassing digestive degradation. Absorption typically occurs within ~60 seconds.

What is Filtraphorix™?

Filtraphorix™ is our proprietary intranasal delivery technology designed to optimize peptide stability and mucosal absorption. It bypasses first-pass digestion for rapid uptake.

How does intranasal compare to oral capsules or IV?

Capsules degrade most peptides in the gut, limiting bioavailability. IV requires a clinic. Intranasal Filtraphorix™ delivery offers high bioavailability with at-home convenience and ~60-second absorption.

How often should I use a nasal spray?

Dosing frequency is reviewed during the required medical intake and tailored to the specific product (Clarity & Focus, DSIP, Cellular Vitality, etc.). We do not publish generalized dosing online.

Is there an age requirement for nasal sprays?

All DrSeinfeld products are intended for adults 18 years and older. Nasal sprays additionally require completion of a medical intake before shipment.

Are there general contraindications for peptide nasal sprays?

Nasal sprays are not recommended during pregnancy, breastfeeding, or for individuals with certain medical conditions. The medical intake screens for contraindications before approval.

Are peptides stable in your nasal spray format?

Yes. Our formulations and packaging are designed for peptide stability throughout the product's shelf life, especially when refrigerated. Each batch is third-party tested for potency.

Can I combine multiple nasal sprays?

Many customers stack products such as Clarity & Focus (daytime) with DSIP (nighttime). Your medical intake review will confirm compatibility for your specific situation.

Supplements

What is the foundational supplement stack?

Our foundational stack includes Vegan Omega-3 Gold, Vitamin DK3, and Potassium Magnesium Zinc — covering essential fatty acids, fat-soluble vitamins, and key electrolyte minerals.

Are your supplements third-party tested?

Yes. Every supplement is manufactured in our GMP-Certified, SQF Level 2 facility and third-party batch tested for identity, potency, and purity.

When should I take my supplements?

Omega-3 and Vitamin DK3 are best taken with a meal containing fat for absorption. Potassium Magnesium Zinc and Sleep Support are typically taken in the evening. Follow each product label.

Are your supplements vegan and gluten-free?

Our Vegan Omega-3 Gold (algae-derived EPA/DHA) and Vitamin DK3 Vegan Formula are plant-based. Check each product page for full allergen and dietary information.
