Headquarters correction: GNC’s current headquarters is at 75 Hopper Place, Suite 501, Pittsburgh, PA 15222. The previously listed 300 Sixth Avenue location is GNC’s former headquarters and should not be used as the current corporate address.
Where Is the GNC Corporate Office?
GNC Holdings, LLC is headquartered at 75 Hopper Place, Suite 501, Pittsburgh, Pennsylvania 15222. The office is located in Pittsburgh’s Strip District, near the city where GNC was founded.
The GNC corporate office phone number is 1-412-288-4600. This number is associated with the corporate headquarters and should not be confused with the company’s primary assistance line for orders, returns, rewards, or subscriptions.
GNC previously maintained its headquarters at 300 Sixth Avenue in downtown Pittsburgh. That address continues to appear on older websites, documents, and directory listings but is no longer the company’s current headquarters.
Who Owns GNC?
GNC operates as GNC Holdings, LLC and is owned by Harbin Pharmaceutical Group Holding Co., Ltd. Harbin acquired GNC’s operating business in October 2020 following GNC’s Chapter 11 restructuring.
The acquisition was completed indirectly through ZT Biopharmaceutical LLC, a Harbin subsidiary. Harbin purchased 100% of the equity interests in the reorganized GNC Holdings, LLC.
GNC is therefore a privately held subsidiary and is no longer traded on the New York Stock Exchange. Older pages that describe GNC Holdings, Inc. as an independent publicly traded company are outdated.
GNC Executive Leadership
Michael Costello is the Chief Executive Officer of GNC. He initially joined GNC as interim CEO and was appointed permanent CEO in September 2024. Current GNC announcements issued in 2026 continue to identify Costello as CEO.
GNC has also recently expanded its executive team in digital commerce, technology, customer experience, merchandising, science, and omnichannel growth. Executive positions can change, so media, vendor, employment, franchise, and business inquiries should confirm current leadership through the official GNC newsroom.
How to Contact GNC About a Corporate Complaint
The appropriate escalation route depends on whether the complaint concerns a retail store, franchise location, corporate policy, product, employee conduct, membership program, or online transaction.
- Document the problem. Keep the receipt, product name, lot number, store location, purchase date, order details, photographs, and any previous GNC correspondence.
- Start with the location or department involved. Store complaints should generally begin with the store manager. Online matters should begin through GNC’s official contact page.
- Request a case number. Record the date, representative’s name or role, response, and promised follow-up date.
- Ask for escalation. If the matter is unresolved, request a supervisor or corporate review and provide a concise timeline.
- Send written correspondence if necessary. Address corporate correspondence to GNC Holdings, LLC, 75 Hopper Place, Suite 501, Pittsburgh, PA 15222.
State the specific resolution being requested, such as a corporate review, store follow-up, refund investigation, product replacement, membership correction, or written response. Send copies rather than original receipts or irreplaceable documents.
Store and Franchise Complaints
GNC operates through a combination of company-owned and independently operated franchise locations. A store complaint should identify the exact location because ownership and management responsibility may differ between locations.
Begin with the store manager when a complaint involves employee conduct, pricing, product availability, return handling, store cleanliness, promotional terms, or an in-store purchase. If the manager cannot resolve the matter, use the official GNC contact page and include the store address, date, approximate time, receipt details, and requested outcome.
Franchise ownership or development inquiries should go through GNC’s official franchise channels rather than the general corporate complaint process.
Product Quality and Supplement Complaints
Product complaints may involve damaged packaging, broken seals, missing safety labels, incorrect products, unusual appearance or odor, foreign material, expired merchandise, suspected counterfeits, or concerns about a product’s lot number.
Keep the product, packaging, receipt, lot number, expiration date, and photographs until GNC or the manufacturer advises what to do. Do not consume a product if its seal appears damaged or if the product seems contaminated, mislabeled, or materially different from its description.
Health and safety warning: GNC corporate staff and public review websites cannot provide medical advice. If you experience a serious reaction, stop using the product and seek appropriate medical assistance. Dietary supplement reactions and serious product-quality problems can also be reported through the FDA’s official dietary supplement reporting process. Do not publish medical records, diagnoses, prescriptions, or other private health information in a public review.
