The Physician Behind Every Formula
Dr. Sasson E. Moulavi
M.D. — Board-Certified Physician · Harvard-Trained · 30+ Years Clinical Experience
Every product on this site carries my name because I review every formulation before it reaches a patient. With over 30 years of clinical experience in longevity, bariatric, and anti-aging medicine, I designed these protocols to deliver the highest-quality peptides with maximum bioavailability.
I don't believe in anonymous supplement brands or unverified claims. Every formula reflects my evidence-based, patient-first approach to cellular health — prepared in a licensed compounding pharmacy under my direct supervision.
"Great health begins with putting the right nutrients into our bodies."
Nasal Sprays
Nasal delivery bypasses first-pass metabolism entirely. Peptides reach systemic circulation in minutes, not hours.
Made differently.
Tested every batch.
Two proprietary technologies shape how our peptides are prepared and delivered. Then every batch goes to an independent lab before it reaches you.
CryoBuffer™
Peptides are fragile in liquid form. CryoBuffer™ is our cold-prepared formulation process, designed to protect peptide structure so your formula stays stable under refrigeration.
- Prepared and filtered cold, at 0 to 4°C, to slow natural breakdown
- Precision buffering to hold pH steady, plus trehalose to help reduce aggregation
- Oxygen-reduced processing and sterile fine filtration before filling
- Shipped ready to use, so there’s no powder to mix at home
Used in: Pen injectables
How CryoBuffer™ works →Filtraphorix™
Taken by mouth, many peptides are broken down by digestion. Filtraphorix™ delivers them across the nasal lining instead, designed to support absorption without a needle.
- Absorbed through the nasal lining, a tissue rich in blood vessels
- Avoids the first pass through the gut and liver that breaks down oral compounds
- Needle-free and simple to use at home
- Prepared in a saline base with no preservatives, fillers, or artificial additives
Used in: Nasal sprays
How Filtraphorix™ works →We check before it ships. Not everyone does.
Many peptides sold online are made overseas in unregulated facilities, and many sellers ship without testing each batch. We screen every batch for fentanyl contamination, so you don’t have to wonder, and we publish the results for your exact lot.

Nasal Spray Delivery
Why Nasal Spray
Outperforms Oral
Active compounds absorb directly through the nasal mucosa — bypassing the digestive system and first-pass metabolism entirely. What you take is what reaches your bloodstream. Oral capsules lose a significant portion of potency before the compound ever enters circulation.
Bypasses First-Pass Metabolism
No gut degradation — compounds enter the bloodstream intact at full concentration.
Direct CNS Access
Olfactory pathways allow certain peptides to reach the brain directly — something no oral format can replicate.
Faster Onset
Absorption begins within minutes of administration — significantly faster than capsules or oral drops.
Subcutaneous Pen Injection
Why Injection Delivers
Maximum Bioavailability
Subcutaneous delivery places the compound directly into tissue adjacent to circulation — no gut degradation, no enzymatic conversion required. The most direct non-IV route available. Precise dose control with every use.
Near 100% Bioavailability
Compounds absorb directly from subcutaneous tissue into circulation — nothing lost to digestion or conversion.
No Conversion Step Required
Unlike oral NMN or NR, subcutaneous NAD+ delivers the molecule directly — no enzymatic conversion, no potency lost.
Precise Dose Control
Dial-a-dose pen injector delivers the exact prescribed volume every time — no guesswork, no inconsistency.

"Absolute game changer. Two weeks in and my focus is sharper than it's been in years. The nasal delivery is fast — I notice it within 20 minutes."
"I was skeptical about the injectable but the doctor review process was smooth and professional. NAD+ results are real — energy is through the roof."
"Sleep has completely changed. Deep and consistent. DSIP spray is the combination I never knew I needed."
