HealingMaps Take: MIHA offers the widest geographic coverage in the Bay Area with three locations: Walnut Creek, Napa, and Atherton. Dual physicians and International Peptide Society membership signal genuine peptide expertise beyond a general wellness offering.
Medical Institute 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.

Your prescribing provider, Dr. Paul Kim, is verified in the federal CMS National Plan & Provider Enumeration System (NPPES) under NPI 1245925460, with a primary specialty of Behavior Technician and a primary practice address in Walnut Creek, CA. CMS records show this NPI has been active since 2023. NPPES record verified 2026-05-08. Dr. Paul Kim’s NPI tenure is the longest-tenured among the 22 California peptide providers we’ve verified in NPPES (longest-tenured peer registered in 2005; cohort median 2007).
What this means for you: In the US, any actively state-licensed physician can legally prescribe compounded peptides — board certification in a specific specialty isn’t required for peptide prescriptions.

Most Medical Institute 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.
Medical Institute 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.
Yes. Dr. Paul Kim is registered in the federal CMS National Plan & Provider Enumeration System (NPPES) under NPI 1245925460, with a primary specialty of Behavior Technician and a primary practice address in Walnut Creek, CA. The NPI has been active since 2023.
Medical Institute 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, Medical Institute 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 (this listing’s clinical lead is Behavior Technician-trained). 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.
We confirmed Medical Institute’s named prescriber in CMS NPPES records. Describes services in general terms rather than naming specific compounds. The clinic doesn’t specify pharmacy class (503A vs 503B) publicly — a reasonable thing to ask about before you book. See our full vetting rubric →
