A national, hormone-focused dual 503A/503B compounder in Colorado whose 503B facilities operate under the entity name BSO LLC.

Belmar is a national compounder best known for bioidentical hormone therapy, operating as both a 503A pharmacy and a 503B outsourcing facility. One attribution detail matters for anyone checking FDA records: Belmar’s 503B facilities are listed by their legal entity name, **BSO LLC**, not “Belmar.”

## Facility & accreditation

Belmar describes itself as a national 503A compounding pharmacy and 503B outsourcing facility [2]. On the FDA Registered Outsourcing Facilities (503B) list, the matching entries are “BSO LLC, Golden, CO” (initial registration January 24, 2024) and “BSO LLC, Lakewood, CO” (initial registration November 24, 2015) [1]; the Belmar↔BSO link is corroborated by matching Colorado cities on both the FDA list and Belmar’s own facility pages. The company’s site lists NABP accreditation, a LegitScript certification, a California sterile license, and Alliance for Pharmacy Compounding membership, and says it serves practices in all 50 states [2] — these are the company’s own statements. Independently, we searched ACHC’s PCAB directory for both “Belmar” and “BSO” and found no PCAB accreditation listed [3]. LegitScript’s own lookup lists belmarpharmasolutions.com as Certified, website type Pharmacy [5]; we did not confirm the NABP accreditation with NABP.

## What they compound

A strong bioidentical-hormone (BHRT) focus — hormones, thyroid, hormone pellets — plus weight management and men’s/women’s wellness [2]. Named compounded GLP-1 (semaglutide/tirzepatide) product listings were not confirmed from the pages we reviewed.

## Regulatory record

Per the FDA 503B list: the Golden, CO (BSO LLC) site was last inspected June 27, 2025, resulting in a Form 483, action status “Open”; the Lakewood, CO (BSO LLC) site was last inspected July 16, 2025, resulting in a Form 483, with an FDA “Regulatory Meeting Held” on March 3, 2026 and a flag indicating a prior compounding-related action in FDA’s history [1]. No warning letter is listed for either Colorado site in that table. The FDA did issue a warning letter on March 31, 2023 addressed to Belmar Pharma Solutions and Drug Depot, LLC dba APS Pharmacy, a 503A pharmacy in Palm Harbor, Florida, citing bulk substances not eligible for 503A compounding and bulk bought from unregistered establishments; the FDA posted a close-out letter dated October 11, 2023 [4]. It is in our [register of warning letters to compounding pharmacies](https://peptidewellnessusa.com/learn/fda-warning-letters-compounding-pharmacies/). A Form 483 documents inspection observations, not a final finding; a regulatory meeting is a step FDA uses to discuss corrections. Dated to our review; status can change.

## The read

A credible national hormone specialist with real 503B registration and 50-state reach. The two recent 483s and the Lakewood regulatory meeting are the items to track (the 2023 warning letter to its Florida pharmacy is closed out); the BSO-LLC naming is the practical gotcha when you go to verify anything in FDA records.
