HealingMaps Take: Dr. Uppal carries a perfect 5.0 ZocDoc rating with a naturopathic root-cause approach to peptide therapy. The focus on gut health, hormone balance (menopause and andropause), and chronic disease prevention fills a niche that most peptide clinics do not address.
Kore Natural Medicine doesn’t list specific peptide compounds on its listing — roughly 1 in 5 of the 40+ California peptide clinics in our directory share that pattern, while the deepest menu in California we’ve reviewed offers 19 compounds.

| Clinical Lead | Dr. Harpreet Uppal, N.D. — Naturopathic Doctor |
Kore Natural Medicine names Harpreet Uppal, N.D as a clinical lead. To verify their NPI, license number, and specialty, look them up directly at the CMS NPPES Registry or your state’s medical board — both are free public databases.
What this means for you: Knowing your clinician’s NPI and license matters because that’s who’s responsible for your protocol, dose adjustments, and follow-up. Any actively state-licensed physician, NP, or PA can legitimately prescribe compounded peptides — verifying takes about two minutes.

Most Kore Natural Medicine patients report the consult-to-first-injection window runs 1–3 weeks depending on lab turnaround and pharmacy fulfillment.
The questions below are pulled from the gaps in this specific listing — areas the clinic doesn’t publicly answer that you should clarify before booking. Each one is designed to get you a useful answer in 30 seconds or less.
Kore Natural Medicine doesn’t publish a specific compound menu on this listing. Ask on the consult call about which peptides — semaglutide, tirzepatide, BPC-157, CJC-1295/Ipamorelin, Sermorelin, PT-141, etc. — they currently prescribe.
HealingMaps editorial wasn’t able to match the named clinical lead to a single NPI in the federal CMS NPPES registry — this can happen when the listing names a generic role (“clinical team”, “supervising physician”) rather than a specific person, or when name variants don’t return an exact match. Ask the clinic to share their physician’s full name and license number on the consult call.
Kore Natural Medicine doesn’t mention telehealth or virtual visits on its listing. Most peptide clinics require in-person evaluation for the initial consult; some offer virtual follow-ups once a patient is stable. If geography or travel matters to you, ask on the consult call whether they can prescribe and follow up virtually — and which states they’re licensed to do so in.
Among verified California peptide clinics in the HealingMaps directory, Kore Natural Medicine ranks in the bottom half of California peptide clinics in the directory by compound depth. Compound depth is one signal among several — provider credentials, pharmacy sourcing transparency, and lab requirements also matter when comparing.

Themes drawn from HealingMaps editorial analysis of verified California peptide clinics in our directory. Refreshed quarterly; percentages rounded to nearest 5%.
Across California peptide clinics in our directory, BPC-157 appears in 55% of listings; Ipamorelin in 45%; CJC-1295 in 40%; Semaglutide in 35%. Compounds appearing in fewer than 20% of California listings — including Epitalon, Thymosin Alpha-1, Semax — are less commonly disclosed; patients seeking those should specifically ask whether the clinic prescribes them.
25% of California clinics in our directory openly state whether they use a 503A or 503B compounding pharmacy. The rest leave the class unstated. The distinction matters for patients — 503A pharmacies fill prescriptions individually after your provider writes them (typically a few-day wait, in-state shipping), while 503B outsourcing facilities pre-batch under direct FDA inspection (often supporting same-visit fulfillment and direct-to-home shipping). Worth asking specifically before you book.
55% of verified California clinics name an MD or DO as clinical lead. The remainder are NP/PA-led or don’t publicly name a specific prescribing clinician. Any state-licensed physician, NP, or PA can legitimately prescribe compounded peptides — but knowing your prescriber’s training and tenure helps you assess fit for your specific protocol.
The median California clinic in our directory publishes 4 specific peptide compounds on its listing. The deepest disclosed menu names 19; 25% of listings name no specific compounds at all. A wide menu means more options at one clinic; a narrow menu can reflect specialization (e.g. weight-loss-only programs) or limited public disclosure (the clinic prescribes more than it advertises).
Pharmacy sourcing: This clinic doesn’t state its 503A or 503B compounding pharmacy partner. The class affects how your prescription is fulfilled — custom-compounded with in-state shipping (503A) versus pre-batched with broader shipping including direct-to-home delivery (503B) — so it’s worth asking before starting any compounded protocol.
Kore Natural Medicine’s menu doesn’t publish a specific compound menu — services are described categorically. The clinic doesn’t publicly name an individual prescriber for CMS NPPES verification or specify pharmacy class (503A vs 503B). Both are common gaps in smaller or newer practices and worth confirming on the consult. See our full vetting rubric →
