The money question
What would I have to pay?
Ask for the whole proposal in writing before agreeing to a charge.
Here, FDA refers to the Food and Drug Administration, the US agency for drugs.
No US maker’s list price existed for an FDA-approved thymosin alpha-1 medicine as of September 28, 2026. No such approved product exists.

What needs to be clear in a written quote?
A proposed care package needs its own written quote. Ask for the amount due now, each ongoing charge, and what is included. Do not treat an advertised price as the total until those answers are clear.
What belongs in the quote?
- The assessment: what is charged if no treatment is offered?
- Tests: which are proposed, why, and who bills for them?
- The medicine: what is its full name, and how much does this price cover?
- Follow-up: which visits or questions are included?
- Delivery or supplies: are there separate charges?
- Renewals: what starts another charge, and how can it be stopped?
Ask the service to label any unanswered item. Then compare the same items across proposals.
Can the price settle the product question?
A low price alone cannot establish that an offer is legitimate; FDA treats implausible discounts as a warning sign alongside other checks.
Check the doctor and pharmacy names. Ask which US rule allows this exact product to be supplied. Keep those answers beside the quote rather than treating the quote as proof.
