The bioavailability problem Absorption comparison: Injection: 80-100% bioavailability (nearly all absorbed) Nasal spray: 30-70% bioavailability (varies by peptide) Oral: 0-5% bioavailability (most peptides destroyed) Why nasal lower than injection: Must penetrate nasal mucosa (barrier) Some drips down throat (swallowed = lost) Variable absorption efficiency Technique-dependent Individual variation high What this means: You need MORE peptide via nasal spray Typically 2-3x higher dose than injection Example: 1mg injection = 2-3mg nasal Increases cost significantly But still cheaper/easier than injection for some Conversion guidelines by peptide PT-141: Injection: 1.5-2mg typical dose Nasal equivalent: 3-5mg Conversion ratio: 2-3x Semax: Designed for nasal use (no conversion needed) Standard nasal dose: 200-600mcg per spray 2-3 sprays per nostril typical Follow product guidelines BPC-157 (if attempting nasal): Injection: 250-500mcg Nasal (estimated): 750-1500mcg But: Injection or oral likely better Nasal BPC-157 not well-studied General conversion approach: Start with 2-3x injection dose Assess results after 2-3 uses Increase by 25-50% if weak effects Find minimum effective nasal dose Individual variation significant Cost implications: Using 2-3x more peptide = 2-3x cost Nasal spray more expensive per dose Trade-off: Convenience vs cost Worth it for needle-phobic Not worth it if injections acceptable Use peptide cost calculator to compare routes
BPC 157 and Probable Toxicity With the increasing interest in the BPC 157 peptide and its application potential, the need to define the risk of probable side effects is also escalating
Oilogic Review: Safe Remedies for Baby In our Oilogic review, we take a deep dive into everything from sourcing and products to customer service, arriving at a rating of BAR-U-EAT Review In our BAR-U-EAT review, well unveil all the juicy (er, chewy?) details we learned after meeting with one of the founders and conducting our own investigation, leading to an overall rating of
The Biology of Hair Follicle Cycling Hair growth follows three primary phases: Anagen (growth phase) Catagen (transition phase) Telogen (resting phase) Healthy follicles require adequate blood supply and signaling from surrounding dermal cells
That is not how we see them
