The WikiPeps Letter
A weekly, plain-English breakdown of one peptide topic — protocols, sourcing literacy, and community field notes. No hype, no sales.
One topic. Covered properly.
Every week we pick one thing and explain it completely. Not a roundup, not a listicle — a real breakdown you can act on.
Peptide deep-dives
Mechanism, typical protocols, reconstitution math, storage — everything on one compound, done properly.
Technique & safety
Subcutaneous injection steps, sterility, site rotation, what to do if something goes wrong.
Sourcing literacy
How to read a CoA, what third-party testing actually tells you, and what it doesn't.
Research breakdowns
When notable papers land, we translate the methodology and findings into plain English.
Community field notes
Real observations from real people — labeled as anecdotal, not presented as evidence.
Protocol primers
Side-by-side comparisons, stacking considerations, timing guides — practical, not prescriptive.

Whether you're curious and haven't started, actively researching, or deep in a protocol — The WikiPeps Letteris for people who believe that understanding what you're doing is part of doing it right.
Common questions
- Is The WikiPeps Letter free?
- Yes — completely free. One thoughtful issue a week, no cost. We make money on supply kits, not the newsletter.
- What topics does The WikiPeps Letter cover?
- Each issue focuses on one topic: a specific peptide protocol, reconstitution science, injection technique, storage and stability, sourcing literacy, or community field notes. We go deep on one thing rather than skimming ten.
- Is this medical advice?
- No. The WikiPeps Letter is educational only. Nothing we publish is medical advice, a prescription, or a recommendation to obtain or use any substance. Always consult a licensed healthcare provider before making any health decision.
- How do I unsubscribe?
- Every issue has a one-click unsubscribe link at the bottom. No dark patterns, no re-subscribe nagging.
- Do you sell peptides or recommend vendors?
- No. We have never sold peptides and we do not affiliate with or recommend any peptide vendor. Our business is injection-supply kits — syringes, prep pads, sharps essentials.
- Are back issues available?
- Yes — every issue is published to the archive on this page once sent. You can browse and read all past issues for free without subscribing.

Storage and handling basics: why the fridge is your friend, why freezing a mixed vial is not, and how to spot a peptide that's gone bad.
Issue 02 — What a 'Unit' Actually Means
Why a unit on an insulin syringe is volume, not peptide — and how that one fact prevents the scariest mistakes.
Issue 01 — Reconstitution Without the Guesswork
The one formula that makes peptide reconstitution math simple — plus why you should never shake the vial.
