## Journal

- [Peptide Storage, Handling and Reconstitution Basics](https://k9peptidesdirect.com/blog/peptide-storage-handling): Lyophilized cakes, diluents, refrigeration, and multi-dose handling — explained from FDA, DailyMed, and CDC sources, without dosing promises.
- [How to Read a Certificate of Analysis (COA)](https://k9peptidesdirect.com/blog/how-to-read-a-coa): What identity, purity, method, and lot number on a COA actually mean — and why a laboratory report is not an FDA evaluation or a medical claim.
- [Supporting Your Senior Dog: Mobility, Cognition and Vet Care](https://k9peptidesdirect.com/blog/supporting-senior-dogs): What AVMA and AAHA actually recommend for older dogs — exams, mobility, and cognitive-change screening — and where research peptides do not replace that care.
- [BPC-157 and TB-500: What the Research Actually Says](https://k9peptidesdirect.com/blog/bpc-157-tb-500-research): A source-checked reading of BPC-157 and thymosin β4 literature: rodent tendon models, gastric reviews, and why TB-500 is not the same as native Tβ4.
- [What Are Peptides? A Plain-English Guide for Dog Owners](https://k9peptidesdirect.com/blog/what-are-peptides): A plain-English look at what peptides are, how they differ from proteins, and why most published work is preclinical — not a canine treatment plan.
