The product selector is visible, but the reviewed strength field is blank. Keep that missing specification in the comparison.

Specification check

The included-service claim and package choices are useful. The missing strength field is a material limit: a vial volume by itself does not establish the amount of peptide, the exact sequence or a comparable price per amount. Resolve that specification before drawing a value conclusion.

Documented details

  • The product page identifies an injectable form and package options.
  • The page states what is included and says a subscription is not required.

Unresolved specifications

  • A general reference to pharmacy categories does not identify the facility assigned to a prescription.
  • Refund wording and product-specific details should be reconciled before payment.

The blank field is part of the finding

The reviewed TB-500 page labels an injectable form and a 10 mL vial but leaves its strength field blank. A volume alone cannot be used to infer total peptide content. Keep the missing field visible rather than substituting a number from another supplier, another product or an older screenshot. Ask for the proposed pharmacy label.

Identity comes before a unit-price calculation

The description relates the offer to thymosin beta-4, but the exact ingredient sequence and form are not established by that wording. Full-length thymosin beta-4 and the fragment sold under a TB-500 label should not be merged. The ingredient identity guide explains why a clinical paper about one preparation cannot automatically support another.

Know what the package claim includes

The selector displays the same $261 one-month and $667 three-month structure recorded above. The page says a visit, medication, supplies and cold shipping are included and no subscription is required. Those are useful service statements to confirm in a written quote. They do not fill the missing strength field or establish how the proposed course compares with another provider’s preparation.

Read the refund boundary in both places

The general terms say fulfilled prescription sales are final and a prescribing denial receives a full refund. Product-page wording places finality once a prescription is approved and sent to the pharmacy. Ask the provider to explain which stage controls your order, including any work already begun. Do not choose the more generous interpretation on the provider’s behalf.

Turn the open fields into written questions

Request the named prescribing professional, dispensing pharmacy and product-state eligibility. A general reference to503A and503B facilities is not a product-specific fulfillment record. The consultation checklist can help you separate those questions from pricing. This publication has not independently verified the assigned licenses, inspected a dispensed vial or established that a catalog listing meets every applicable compounding condition.
