About GLP321
Is this site affiliated with any provider?
No. We take no commissions and no sponsored placements. More on who we are and how the data is collected is on the About page.
What does the Reddit Community filter mean?
These are providers tracked by the r/tirzepatidecompound community in its regularly updated provider list. That community is part of what inspired GLP321 and our goal of making medication information easier to find and compare. The filter is a community signal, not our endorsement, a ranking, or a paid placement. We keep the list by hand and update it as the community's list changes.
How to use the site
How does the comparison page work?
The homepage is a sortable, filterable list of every provider we track. The filter rail across the top controls what you see, and the provider cards below update live.
What do the medication, price, and dose filters do?
The medication filter switches between tirzepatide, semaglutide, and retatrutide. Retatrutide is investigational, not FDA-approved and not available by prescription, so its tab shows a Coming Soon panel.
The price filter toggles between Monthly, Bundle, and Starter views. Monthly is recurring billing. Bundle is upfront multi-month. Starter shows the discounted intro offers some providers run for your first cycle.
The dose filter jumps every card to that tier's price for the dose you are on.
What is the difference between a plan, a program, and a package?
Providers use these words loosely, but there is a rough pattern. A plan usually means month-to-month billing. A program usually means a term agreement that runs a set number of months. A package is usually prepaid, one upfront payment for a multi-month supply. We list every offer as a plan and show its real billing and commitment on the card, whatever the provider calls it.
What do AVG/MO and the other card labels mean?
- AVG/MO: the card's default headline price, an average across dose tiers.
- WHAT YOU ACTUALLY PAY: what you actually pay for the selected dose per billing cycle.
- WHAT YOU ACTUALLY GET: the total mg and weeks of supply in that cycle.
- YOUR VALUE: effective price per mg.
What does BUD (Shelf Life) mean?
The sealed-vial window: how long the vial stays usable from the date the pharmacy prepared it, which is the number compounders publish. A second clock starts at first use. Under USP 797, the rulebook for sterile compounding, a preserved multi-dose vial is good for 28 days after the first puncture unless its label states otherwise. The two clocks are separate, and the pharmacy's own label is the authority on both.
GLP-1 medications and terms
What is the difference between compounded and brand?
Brand-name GLP-1s like Zepbound and Wegovy come from the manufacturer and are FDA-approved. Compounded GLP-1s are made by a 503A or 503B pharmacy and are a pricing alternative to the brand versions. They are intended to contain the same active ingredient, though compounded versions are not FDA-approved or verified as equivalent. How to weigh the two is covered in Getting Started.
What are 503A and 503B pharmacies?
503A pharmacies compound medications to order for an individual patient's prescription. 503B outsourcing facilities register with the FDA and make larger batches under stricter federal quality oversight. A dispensing pharmacy fills and ships medication prepared elsewhere rather than compounding it.
Are compounded GLP-1s legal?
Compounded GLP-1s may be prepared by licensed pharmacies when federal and state requirements are met. They are not FDA-approved, and their status can change over time. See the medical disclaimer for details.
What is the FDA shortage status?
Resolved for both medications: the FDA declared the tirzepatide shortage over in December 2024 and the semaglutide shortage over in February 2025, and it has since proposed ending bulk 503B compounding of both. The full timeline, what it means for availability, and live provider counts are on the tirzepatide compounded and semaglutide compounded pages.
What is titration?
The ramp built into GLP-1 treatment: doses start low and step up on a schedule, usually every 4 weeks, so your body can adjust. Some providers sell that ramp as one titration plan covering several dose tiers for one price, and we show those as a single plan with the included doses listed inside it. The full schedules by medication are on the Dosing Schedule page.
What is microdosing?
A provider term with no single fixed meaning. Plans sold as microdose or microdosing typically spread smaller injections across the week, for example twice-weekly low-dose shots rather than the standard once-weekly schedule. Each provider defines its own version and schedule, so we list these plans as the provider publishes them. It is a dosing format some providers offer, not a recommendation.
Pricing and comparison
Why does the "average" price not match my dose?
The average is a cross-dose number for quick scanning. Select your specific dose to see the actual cost.
How current are the prices?
Every price comes from the provider's own public pages and is re-checked on a rolling schedule, so what you see reflects the latest public information we have for each provider. Every provider's pricing carries a last-verified date from our most recent check.
