TB-500 peptide in Las Vegas, and where it actually stands

No. TB-500 is not an FDA approved medication for any use, and it is not on the FDA's 503A bulks list, which is the list of substances a compounding pharmacy may lawfully prepare. It appears instead on the FDA's list of bulk substances that may present significant safety risks, with the status nominated but withdrawn. In the FDA's own words, the agency "lacks important information regarding any safety issues raised by this drug, including whether it would cause harm if administered to humans."

No. Las Vegas Mobile IV Therapy does not sell, prescribe, or administer TB-500, and we do not handle products labeled for research use only or not for human consumption. Because TB-500 is not on the 503A bulks list, there is no compliant pharmacy route to source it. What we do offer is a consultation with a Nevada licensed provider who can tell you which compounded peptides are actually available to you.

Thymosin beta-4 is a naturally occurring protein of 43 amino acids that binds actin. TB-500 is not that protein. It is a synthetic fragment of seven amino acids, the sequence LKKTETQ, copying residues 17 to 23 of thymosin beta-4. The FDA lists the fragment as its own substance for that reason. It matters when you read research, because a study on the full protein is not evidence about the fragment.

The FDA states it has identified no human exposure data for drug products containing the thymosin beta-4 fragment. Most literature people cite for TB-500 studies the full length thymosin beta-4 protein, not the seven amino acid fragment sold as TB-500. We link the published literature so you can read it yourself. We make no claim that TB-500 does anything for anyone, because the evidence to support such a claim does not exist.

We do not publish one. Dosing guidance for a substance we do not dispense, that has no FDA approval and no human safety data on record, would be guesswork presented as medical advice. Anyone publishing a TB-500 dose is not working from an established human safety profile. If you have a recovery goal, a provider consultation is the honest route, and dosing for anything actually prescribed is set by that provider.

There is no established human side effect profile, which is itself the finding. The FDA's evaluation notes that compounded drugs containing the thymosin beta-4 fragment may pose a risk for immunogenicity for certain routes of administration, due to the potential for aggregation and peptide related impurities, and that the agency has identified no human exposure data. An unknown risk profile is not the same as a clean one.

Separate from any safety question, TB-500 and thymosin beta-4 are prohibited at all times under category S2 of the World Anti-Doping Agency Prohibited List, in and out of competition, as non specified substances. Anti doping laboratories test for the synthetic fragment directly. If you are a tested athlete at any level, a positive test carries a sanction regardless of your reason for taking it. Check the rules that apply to your sport before anything else.

Neither is dispensed here, so we are not the right source for a comparison. What is worth knowing is that both sit in the same regulatory position: each was nominated for the FDA's 503A bulks list and withdrawn, and each appears on the FDA list of bulk substances that may present significant safety risks. Choosing between two substances that no compounding pharmacy may lawfully prepare is not the useful question.

Your provider confirms the cost of a consultation and of anything prescribed before you commit to it. Peptide therapy is elective and generally not covered by insurance, so most clients pay out of pocket. Every peptide we do dispense carries a published supply price, and what our services cost in Las Vegas covers the wider menu. There are no hidden visit fees inside our standard service area.
