Who Will Prescribe Your Peptides?
Your prescribing provider, Dr. Clark Gaston, is verified in the federal CMS National Plan & Provider Enumeration System (NPPES) under NPI 1437601135, with a primary specialty of Naturopath and a primary practice address in Phoenix, AZ. CMS records show this NPI has been active since 2016. NPPES record verified 2026-06-09. Dr. Clark Gaston’s NPI tenure is shorter-tenured than most of the 6 Arizona peptide providers we’ve verified in NPPES (longest-tenured peer registered in 2006; cohort median 2010).
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.

Is Strength Doctor the right fit for you?
✓ Choose Strength Doctor if:
- You’re in or willing to travel to Tempe — peptide therapy generally requires in-person consultation and ongoing follow-ups.
- You want a broad compound menu — this listing names 11 specific peptides, among the deepest in the market.
- You want custom-compounded peptides (dose tailored to you) — this clinic discloses 503A sourcing.
✗ Look elsewhere if:
- You need to start treatment within the same week. Most peptide programs require baseline labs (1-3 days) plus pharmacy fulfillment (a few more days) before your first dose — plan on 1-3 weeks from consult call to first injection.
- You’re shopping primarily on price and need per-compound rates published up front. Most clinics share specific pricing only on the consult call. Use our cost calculator above for ballpark estimates and confirm specifics with the clinic.
- You need direct-to-home shipping across state lines — 503A pharmacies typically can’t ship out of state.
What to Expect at Your First Strength Doctor Appointment
- Initial consultation / intake — typically 30–60 minutes reviewing medical history, goals, current medications, and prior labs.
- Baseline lab work — most clinics require labs before prescribing growth-hormone secretagogues (CJC-1295/Ipamorelin, Sermorelin) and GLP-1s (semaglutide, tirzepatide), since those compounds modulate endocrine and metabolic pathways. Tissue-repair peptides (BPC-157, TB-500), sexual-wellness peptides (PT-141), and topical compounds are sometimes prescribed without labs. This listing doesn’t explicitly state lab requirements, so confirm on your consult call which panels they require for your specific protocol. Even when labs aren’t strictly required, they’re a smart personal baseline. See our guide to peptide therapy lab work for what to ask about.
- Protocol design — this listing publishes a deep menu (11 compounds, including BPC-157, CJC-1295, Ipamorelin, Sermorelin, and others). Your provider narrows the protocol based on your goals, labs, and any contraindications.
- Prescription written + sent to compounding pharmacy — Because the clinic discloses a 503A compounding pharmacy partner, your prescription will be compounded individually after your provider writes it — typically a few-day wait for in-state delivery or pickup.
- Self-administration training — for injectable peptides, the clinic walks you through subcutaneous injection technique, needle handling, refrigeration, and rotation sites.
- Follow-up — typically a 4–6 week check-in to assess response, side effects, and whether dose or compound needs adjustment.
Most Strength Doctor patients report the consult-to-first-injection window runs 1–3 weeks depending on lab turnaround and pharmacy fulfillment.
What to Ask on Your Strength Doctor Consult Call
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.
- “Of these 11 compounds, which do most patients with my goals end up on?” A deep menu can mean either deep expertise or unfocused offerings — ask which compounds the clinic actually has the most experience with.
- “If I move out of state, can your 503A pharmacy still fulfill my prescription, or will I need a new clinic?” 503A pharmacies generally can’t ship across state lines.
- “Which lab panels do you require for the protocol you’d recommend for me?” Clinics typically require baseline labs for hormone-modulating compounds (semaglutide, tirzepatide, growth-hormone secretagogues) and may skip them for some tissue-repair or topical compounds. Knowing your clinic’s specific lab requirements helps you compare to peers — and even when not required, baseline labs are smart personal protection.
- “Is this entirely cash-pay, or do you accept any insurance for the GLP-1 path (semaglutide, tirzepatide)?” Compounded peptides are almost never covered, but brand-name GLP-1s sometimes are with prior authorization.
- “What’s the total first-month cost — consult fee, labs, and initial prescription combined?” First-month all-in is usually 1.5–2× the recurring monthly cost. Ask for an itemized breakdown.
- “Is follow-up telehealth-friendly, or are in-person visits required at every milestone?” The listing doesn’t mention telehealth — important to know if you travel or move.
- “From my consult to my first injection, how long is the typical timeline?” Lab turnaround + pharmacy fulfillment usually means 1–3 weeks. Confirms expectations.

Is the clinical lead at Strength Doctor a verified physician?

Does Strength Doctor offer telehealth or virtual visits?
Strength Doctor 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.
How does Strength Doctor compare to other Arizona peptide clinics?
Among verified Arizona peptide clinics in the HealingMaps directory, Strength Doctor ranks in the top half of Arizona 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.
Where is Strength Doctor located?
Strength Doctor is located in Tempe, Arizona. The full street address, phone number, and hours are listed in the data card above.
What Arizona Peptide Patients Are Likely Asking
Themes drawn from HealingMaps editorial analysis of verified Arizona peptide clinics in our directory + CDC PLACES 2023 (Maricopa County, AZ) + US Census ACS 5-Year. Refreshed quarterly; percentages rounded to nearest 5%.
Which peptides do most Arizona clinics actually offer?
Across Arizona peptide clinics in our directory, Semaglutide appears in 95% of listings; Tirzepatide in 95%; BPC-157 in 65%; CJC-1295 in 65%. Compounds appearing in fewer than 20% of Arizona listings — including Selank, AOD-9604, Thymosin Alpha-1 — are less commonly disclosed; patients seeking those should specifically ask whether the clinic prescribes them.
How transparent are Arizona clinics about their compounding pharmacy?
35% of Arizona 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.
Who’s actually prescribing peptides in Arizona?
20% of verified Arizona clinics name an MD or DO as clinical lead (this listing’s clinical lead is Naturopath-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.
How deep are Arizona peptide menus typically?
The median Arizona clinic in our directory publishes 10 specific peptide compounds on its listing. The deepest disclosed menu names 15; every clinic names at least one compound. 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).
What does Phoenix’s health profile mean for peptide demand?
In Maricopa County, 30.4% of adults are obese (CDC PLACES 2023) — roughly at the national average — supporting balanced demand between weight-loss and longevity protocols. Diagnosed diabetes runs at 10.6%. 12.9% of adults lack health insurance, roughly average for the country.
How many peptide clinics serve Phoenix?
20+ verified peptide clinics serve Maricopa County’s ~4,431K residents (0.5 per 100K) — roughly average peptide-clinic density for U.S. metros. Comparing 3-5 clinics on consult calls is a reasonable benchmark before booking.
Pharmacy sourcing: This clinic discloses a 503A compounding pharmacy partner. As a patient, that means your prescription is compounded individually after your provider writes it — typically a few-day wait, with shipping usually limited to within Arizona, and dose customization often possible.
How we vetted this clinic
When a clinic both names a verifiable prescriber and discloses 503A pharmacy sourcing, the regulatory side is generally well-handled. Strength Doctor fits that pattern: prescriber NPI confirmed in CMS NPPES, publishes 11 compounds (BPC-157, CJC-1295, and Ipamorelin lead the list), 503A compounding through a state-licensed pharmacy.
