TB-500 Online

TB-500 is a lab-made peptide based on thymosin beta-4 (Tβ4), a small protein found in nearly all human and animal cells. When prescribed, it is prepared as a compounded medication and typically administered as a small subcutaneous injection, with dosing set by your clinician.

What TB-500 is

Thymosin beta-4 binds actin — a building block of the cellular skeleton — and plays a role in how cells move, which is central to wound repair, blood-vessel formation, and tissue remodeling. TB-500 replicates the active region of that protein.

How it has been studied

The thymosin beta-4 literature includes extensive animal work — dermal wound-healing, corneal injury, and cardiac-repair models — and, uniquely among recovery peptides, some early-phase human trials in non-injected forms such as eye drops for corneal healing (see references).

TB-500 versus BPC-157

TB-500 and BPC-157 are often discussed together, but they are different molecules: TB-500 works through cell-migration biology, while BPC-157 derives from a gastric protective protein with findings concentrated in tendon and gut-lining repair. A provider can discuss whether either fits your situation.

Why a provider consultation matters

Compounded TB-500 dispensed through this program is not FDA-approved; the FDA does not review compounded drugs for safety, effectiveness, or quality before marketing, and no version of thymosin beta-4 has completed the trials needed for approval. A licensed provider determines whether treatment is appropriate after reviewing your history, medications, and goals. You can start the online consultation here.

Human safety data for injected TB-500 is limited, and it is not appropriate for everyone. Reviewing the following with a licensed provider is an essential part of treatment.

Potential side effects

Reported effects are generally mild and may include injection-site redness or irritation, occasional headache, or brief lethargy after dosing. Because the long-term profile is not established, report any unusual or persistent symptoms to your care team, and seek prompt medical attention for severe reactions such as difficulty breathing or signs of an allergic reaction.

Who Should Not Use TB-500?

TB-500 is generally avoided during pregnancy or breastfeeding and in people with active cancer or a cancer history, because cell-migration and blood-vessel pathways are the concern. Competitive athletes should not use it: thymosin beta-4 is prohibited by the World Anti-Doping Agency and has featured in doping cases. Your provider reviews your history and will decline treatment when it is not safe or appropriate. Not everyone who applies will qualify.

Drug-interaction review

Share a complete list of your prescriptions, over-the-counter products, vitamins, and supplements during your consultation so your provider can check for potential interactions. Never start, stop, or change a medication without talking to a licensed provider.

When to contact a medical provider, and why results vary

Contact your provider if you experience side effects, have questions about dosing, or notice anything unexpected. Individual results vary, robust human evidence for injected TB-500 is limited, and no specific outcome is guaranteed.

Compounded medications are not FDA-approved. The FDA does not review compounded medications for safety, effectiveness, or quality before they are marketed. A licensed provider determines whether a compounded medication is appropriate for an individual patient.

TB-500 sits in a family of peptides explored for recovery and wellness. BPC-157 is studied through gut-derived tissue protection, while sermorelin — a growth-hormone-releasing peptide with a longer clinical history — works on the pituitary’s GHRH receptor. Some protocols discuss combining peptides, but any combination decision belongs to a licensed clinician.

Which peptide, or combination, is appropriate depends entirely on your goals, health history, and a licensed provider’s assessment. The compounded peptides offered through this program are not FDA-approved for these uses and are dispensed only by prescription through licensed compounding pharmacies.

A DripVitals TB-500 program is a clinician-guided subscription that bundles your care and medication. Depending on what your provider prescribes, it typically includes:

• Online medical consultation and licensed-provider review
• Your prescribed TB-500 from a licensed compounding pharmacy
• Home injection supplies, where applicable
• Free, discreet shipping
• Ongoing messaging access to your care team
• Follow-up check-ins with dose adjustments when clinically appropriate
• A subscription you can cancel at any time

TB-500 Injection Cost and Pricing

Pricing depends on the plan you choose and what your provider prescribes. There are no hidden fees, and your dashboard shows exactly what you pay and when.

*Monthly rates reflect plan length: $199/mo billed $597 every 3 months, $189/mo billed $1,134 every 6 months. Actual price depends on the plan and treatment prescribed. Plans are offered as a subscription that can be canceled at any time.
