What this actually is
Before you decide, understand it.
Mechanism
Cofactor in energy metabolism, red blood cell formation, nerve myelination and the methylation cycle.
B-12 is the least exotic product we sell and one of the most consistently useful. Methylcobalamin is the active form, which matters because a meaningful share of the population carries genetic variants that make converting the cheaper cyanocobalamin form inefficient. Deficiency is common, under-diagnosed, and presents as exactly the fatigue people usually blame on everything else.
What to expect, and when
Timelines are compound-specific. Here's this one's.
Week 1–2
If you were deficient, this is where you notice.
Ongoing
Maintenance rather than a course.
Good to know
The things we'd tell you in person.
- 01
Methylcobalamin, not cyanocobalamin — the difference matters for absorption.
- 02
A sensible baseline addition to almost any protocol.
- 03
Worth getting actual bloodwork rather than guessing.
Why collagen production falls, and what signals it back
The biology behind the change you can see in the mirror, and why topical collagen cannot fix it.

Common questions.
Anything not covered here, ask us directly — English or Spanish.
Ask about B-12 →Peptides ship as a freeze-dried powder because they are far more stable that way. Reconstitution is adding bacteriostatic water to turn that powder into a measurable liquid. It matters because the ratio you choose determines what every subsequent dose actually contains — get the ratio wrong and every dose after it is wrong too. Our reconstitution kit includes a chart so you are not doing the arithmetic yourself.
Unopened lyophilised vials are stable at room temperature, away from light. Once reconstituted, refrigerate — and write the date on the vial, because you will not remember it. Do not freeze a reconstituted vial. Do not shake one; swirl it gently.
It depends on the compound. GLP-1 compounds change appetite within a week or two. Collagen-signalling peptides need six to ten weeks because new collagen has to physically be built. Recovery compounds usually show up around week three. Every product page on this site has its own timeline for exactly this reason.
No. Our products are sold as research compounds, which is why every vial is labelled for research use and why nothing on this site is presented as medical treatment. Deciding whether something is appropriate for you sits with you and whoever advises you.
You choose how to pay while you check out — Zelle, Cash App or Venmo — and the details appear the moment you place the order, along with your order number. No cards, and no card details are collected anywhere on this site. Put that order number in the payment note: it is the only thing linking your payment to your order. Every order is confirmed personally, and once a C.N.M Agent has seen the payment it moves to fulfilment with a tracking number.
Unopened, unused items in original packaging can be returned within 14 days of delivery. For safety reasons we cannot accept returns on anything that has been opened or reconstituted. If something arrives damaged or wrong, tell us and we will replace it.
