Key Questions Before You Request Quotes

Can I get Vitamin C (Ascorbic Acid Injectable) compounded?

Possibly. A licensed prescriber has to decide whether Vitamin C (Ascorbic Acid Injectable) is appropriate, and a licensed compounding pharmacy has to confirm it can legally prepare the requested strength, form, and quantity for Ontario, CA.

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.

Why Compare Vitamin C (Ascorbic Acid Injectable) Prices in Ontario?

Prices for the same compounded prescription often differ widely between pharmacies — on almost half of the requests we compared (all medications combined), the highest quote was at least double the lowest. Ontario patients can be quoted very different prices depending on whether the pharmacy is local, ships from out of state, or sources ingredients differently.

By comparing quotes from multiple licensed pharmacies that serve Ontario, you can find the best combination of price, quality, and convenience without spending hours making phone calls.

How uploads are used

By uploading, you consent to AI-assisted parsing to extract medication details and pre-fill the form. 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.

Pet details
Veterinary pharmacies usually need species and weight before quoting. Form or flavor preference helps them quote the right preparation.

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.

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 →
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.

Pharmacies quote faster when they understand the purpose — especially for higher doses or unusual formulations. Share only what you're comfortable with.
Allergies, inactive ingredients to leave out, and base or flavor preferences. Name the exact ingredients — a pharmacist compounds to an ingredient list, and “MCAS-friendly” on its own does not say what to avoid or what you tolerate.
