Why we host reviews ourselves
External review platforms remove research-peptide vendors by category — not for misconduct. Why that's a structural problem, and why we host reviews on our own independent infrastructure so they stay put.
Fridge vs. freezer
Freezer is not always better. For lyophilized powder, colder wins. For reconstituted peptides, the freezer's freeze-thaw cycle can do more damage than the fridge ever would — here is the actual mechanism, and the aliquoting fix.
How peptides are tested
On the gray market a label is just a claim until a lab confirms it. The levels of testing, where samples fall short, the labs that matter, and how to test individually or as a group.
Single-vial vs 10-vial kit vendors
Two suppliers can list the same peptide with the same certificate of analysis, yet one charges up to twenty times more. Here is why single-vial sellers and 10-vial kit sellers price so differently — and the one number that lets you compare them honestly.
Why mislabeled BAC water
Independent reports and community testing have repeatedly flagged marketplace-sourced "bacteriostatic water" that turns out to be plain sterile water or saline — missing the benzyl alcohol preservative entirely. Here's what the difference actually means, and why Pfizer's Hospira-branded product has become the reference point researchers compare everything else against.
Khavinson bioregulators
A Russian gerontology research program spanning five decades produced more than twenty ultra-short peptides, each proposed to act on a specific organ. Here is the history, the theory, an honest look at the evidence, and an index to every one of the 20 compounds PeptideCompare now tracks.
NMN tablet vs NAD+ injection
NMN at 500–1000mg in tablet form is more practical, better absorbed, and more cost-effective than direct NAD+ for most protocols. Here is the science behind why.
All NAD+ precursors explained
Not all NAD+ precursors are equal. Here is a complete guide to every major precursor, how they differ biochemically, and what the evidence says about each.
NAD+ synergists
NMN raises NAD+. But NAD+ is only part of the longevity equation. These compounds amplify the effect — through sirtuins, methylation support, and mitochondrial synergy.
Senolytics & senomorphics
Senescent cells accumulate with age, releasing inflammatory signals that damage surrounding tissue. Senolytics clear them. Senomorphics neutralize them. Here is everything you need to know.
What a real COA tells you
A Certificate of Analysis is only as good as the lab that issued it. Here is how to read one, which labs to trust, what to look for, and what contaminants are actually found in substandard peptides.
