Making the same recipe in bulk and posting it interstate as injection pens is really manufacturing, which needs a licence

Reputable vendors provide complete documentation including synthesis methods, testing protocols, and storage recommendations specific to BPC 157 peptide research applications

Key Characteristics Defined synthetic amino acid sequence for analytical reproducibility Produced using standardized SPPS synthesis workflow Freeze-dried (lyophilized) formulation for stability during transport Batch-controlled manufacturing for consistency across production lots Validated through chromatographic and mass spectrometric methods Manufacturing & Analytical Verification BPC-157 is manufactured using solid-phase peptide synthesis (SPPS), a widely adopted method for controlled assembly of amino acid sequences

I cant help wondering if your methods have an element of robbing Peter to pay Paul
