Ignoring the enteric coating assumption Many capsule products are not enteric-coated and rely entirely on the acid-stability argument
While the exposure from bacteriostatic water is very low, there is a theoretical risk that an infant could ingest benzyl alcohol through breast milk

Example protocols with 100mg Skin rejuvenation protocol: Goal: Improved skin texture, reduced fine lines, enhanced collagen Dose: 2mg subcutaneously, 5 days/week Duration: 10 weeks Total peptide: 100mg exactly Reconstitution: Full vial at start, use within 30 days for first 60mg, freeze remainder in sterile vial, thaw at day 28 Recovery: 6 weeks off before considering second cycle Intensive hair support protocol: Goal: Hair follicle stimulation, reduced shedding, improved density Dose: 2mg daily, 7 days/week Duration: 7 weeks (one vial), then reassess Total peptide: 98mg (leaves tiny remainder) Reconstitution: Full vial, use 60mg in first 30 days, frozen portion for remaining 38mg Recovery: 4-8 weeks off, then evaluate need for second vial Conservative longevity protocol: Goal: General anti-aging, skin health maintenance, systemic benefits Dose: 1mg daily, 5 days/week Duration: 20 weeks (two 10-week blocks with reconstitution in between) Total peptide: 100mg Reconstitution: 50mg initially, frozen 50mg for second batch Recovery: 8-12 weeks off annually The getting started guide covers fundamentals for those new to peptide research

This area should be presented with greater caution than the gastrointestinal and cell-migration literature because the mechanistic questions are more difficult
