Key Questions Before You Request Quotes

Can I get Phentermine (Compounded) compounded?

Possibly. A licensed prescriber has to decide whether Phentermine (Compounded) is appropriate, and a licensed compounding pharmacy has to confirm it can legally prepare the requested strength, form, and quantity.

Is a prescription needed?

Yes. Patient-specific 503A compounding is based on a valid prescription order or prescriber notation for an identified patient.

What affects price?

Strength, dosage form, quantity, ingredient sourcing, sterile versus non-sterile preparation, shipping requirements, and each pharmacy's workflow can all change the final quote.

How fast can I get quotes?

For routable requests, Compounding Finder typically returns quote options by email within 1-2 business days after you submit the request details.

What happens after I submit?

We review the request, route it to eligible licensed pharmacies, collect available options, and email you the quoted choices. You decide whether to move forward with a pharmacy.

Source notes: FDA explains that compounded drugs are not FDA-approved finished products and describes 503A compounding around patient-specific prescriptions. See Compounding and the FDA and Section 503A.

What Affects Phentermine (Compounded) Pricing?

Compounded Phentermine (Compounded) prices vary by 300%+ between pharmacies. Key factors include:

Dosage and strength — higher doses cost more
Formulation — injections, capsules, creams, and troches have different costs
Quantity — larger orders often have lower per-unit pricing
Pharmacy location — overhead and ingredient sourcing vary regionally
Shipping — cold-chain medications (injections) cost more to ship

If you submit this request, the prescription file is saved with your quote request so Compounding Finder can verify medication, quantity, allergies, and other details before outreach. Pharmacies will not be able to view the uploaded file through the portal at this time. The AI parsing step is used only to extract form details and is not used for training.

Note: Tirzepatide & Semaglutide can only be compounded for patients with a documented medical necessity — such as an allergy to an inactive ingredient or need for an alternative formulation. Diagnosis alone (e.g. weight loss, type 2 diabetes) and cost are not valid reasons under FDA 503A. Wegovy and the single-dose Zepbound and Mounjaro pens and vials are already preservative-free, so that on its own is not a reason either.

Brand-specific reason for compounding *

Required by your pharmacy under FDA 503A. The Rx must document this reason — the pharmacy will reject a generic or diagnosis-only justification.

We can no longer fulfill compounded Natural Desiccated Thyroid (NDT) requests. The FDA is taking enforcement action against unapproved animal-derived thyroid products, and US compounding pharmacies are no longer filling NDT prescriptions. FDA-approved alternatives — Armour Thyroid, NP Thyroid, and WP Thyroid — remain available at retail pharmacies with a prescription. See alternatives →

Quantity Needed *

Prescription quantity tip: enter the amount dispensed in one fill. For example, if your Rx says "60 capsules, refill ×2", enter 60, not 180. For creams, gels, lotions, foams, and transdermal/vaginal preparations, choose grams or mL exactly as written.

How often will you take this? *

Helps us match you to the right pharmacy and time your refills.
