"I don't think it's working" Possible causes: Dose too low (most common) Solution: Increase by 25-50% Nasal absorption variable May need higher end of dosing range Poor technique Solution: Review technique above Head position critical Not sniffing hard Alternating nostrils Swallowing too much Solution: Keep head forward Wait longer between sprays Don't swallow for 2-3 minutes after Peptide not suitable for nasal Solution: Switch to injection Some peptides don't work nasally Try injection for comparison Degraded peptide Solution: Check storage, expiration Refrigerate always Use within 28-30 days Nasal irritation or burning Causes and solutions: High concentration: Too concentrated = irritation Solution: Dilute to lower concentration Balance between volume and concentration 5-10mg/ml usually tolerable Improper pH: Very acidic or basic = burning Solution: pH buffer (advanced) Or: Buy from reputable source with proper formulation DIY risks this issue Allergic reaction: Rare but possible Solution: Discontinue use Try different peptide Consider injection instead Nasal congestion: Congested nose = poor absorption Solution: Clear nose first Saline spray 10 minutes before (optional) Or skip dose if severely congested Dripping or running nose Causes: Too much volume at once Head tilted wrong Solution dripping from nose or throat Solutions: Use less volume per spray Perfect head position (slightly forward) Wait longer between sprays Reduce total volume (higher concentration) Wipe nose after dosing (normal) Nasal spray vs injection: The honest comparison Making the informed choice

What it costs Legitimate BPC-157 10mg (HPLC 99.6%, COA included): $69-$89 | Suspicious "budget" BPC-157 10mg (no COA, unverified purity): $15-$30 | The price gap is not a bargain it reflects the absence of the synthesis quality, third-party testing, and documentation that make a compound usable for serious research
