About TB-500 (TB4)
The listing uses the name TB-500 (TB4). The supplier’s separate molecular reference uses a TB-500 fragment record. These identities should not be assumed to be equivalent. [1]
Confirm the exact sequence and batch documentation with Sparta Labs before matching this material to published literature. No molecular formula or fragment-specific identifier is reproduced here because of that discrepancy.
