In the case of BPC-157, compounders obtain the raw peptide (synthesized via solid-phase chemical synthesis) and then prepare it into injectable vials, nasal sprays, or capsules per a doctors prescription. Clinics and online research chemical websites also sell BPC-157 directly to consumers, often labeling it for research use only to skirt regulations
While TB-500 has intriguing animal data, as it stands, there are no standardized, evidence-based TB-500 dosage guidelines from large human studies
TB-4 is not the same molecule as TB-500, the shorter 1723 fragment, even when product labels use the names interchangeably. The shared three-peptide rationale is mechanistic
