Featured compound guides.
Every guide carries an evidence stage based on the published research we have actually logged.
Tirzepatide
Human randomized trialTirzepatide is a 39-amino-acid dual agonist of the GIP and GLP-1 receptors, approved in the US as a prescription medicine for type 2 diabetes and obesity (Mounjaro, Zepbound).
Read GuideBPC-157
Insufficient identified evidenceBPC-157 is a 15-amino-acid synthetic peptide derived from a protein found in human gastric juice.
Read GuideGHK-Cu
Insufficient identified evidenceGHK-Cu is a naturally occurring tripeptide (glycine–histidine–lysine bound to copper) identified in human plasma in 1973.
Read GuideSemaglutide
Human randomized trialSemaglutide is a long-acting GLP-1 receptor agonist — a modified peptide given by once-weekly injection (or daily oral tablet) — approved as Ozempic, Wegovy, and Rybelsus for diabetes and obesity.
Read GuideClear inputs. Clear calculations.
Three values in, two results out. Everything runs in your browser, and nothing you type is saved or sent to analytics.
This is a mathematical tool. It converts the values you enter into a concentration and a volume. It does not recommend doses, schedules, titration, or administration, and it is not medical advice. Research and education only.
Example values — not recommendations
The total amount in the vial, as printed on the label or certificate of analysis.
mL
Final total volume in mL after any diluent is added. The calculation assumes the number you enter is the final volume.
A value from your own research reference. No dose is suggested here, and nothing is inferred from a compound name.
Single-compound calculations only. Blends need a quantity for each component, which this tool does not infer from a product name. Calculations run entirely in your browser.
Result
Enter the material amount, solution volume, and target amount to see results.
Mathematical output only. This tool does not recommend a dose, schedule, or route of administration, and it is not medical advice. Calculated precision is not measurement resolution — a calculated volume may be finer than any marking on a physical measuring device.
How we evaluate research.
How sources are selected
We cite published research, regulator documents, and testing-lab reports. Each guide links the sources it uses so you can read them yourself. We do not cite vendor marketing as evidence.
Sources & methodologyEvidence stages
Every study record carries a stage that describes the kind of research it is — human randomized trial, other human research, animal, or laboratory. A stage never says a compound works or is safe.
See the study libraryLimitations and review dates
Guides state what the research does not settle and when the page was last reviewed. When we get something wrong we correct it in the open rather than quietly editing.

mg vs mcg vs mL: How to Read a Peptide Dose Correctly
Read 0.5 as 5 and you have made a ten-times mistake, and the FDA has reported exactly that with compounded semaglutide. This guide separates the three units that get confused, explains what U-100 markings really measure, and works one calculation end to end.

I'm calling it now: the peptide conversation is moving to X
The health secretary wants a regulated peptide marketplace and the FDA has a compounding proposal under review. If access opens, telehealth money follows, and certification bodies will decide who gets to advertise. Here is why the conversation itself may end up somewhere with no ad review.

GLP-1 Weight Regain: What the Tirzepatide Trials Show
Most people who stop tirzepatide regain some weight, but the trials do not show that it is a discipline problem. Here is what SURMOUNT-4 and SURMOUNT-MAINTAIN actually measured, why a lower maintenance dose kept more weight off than stopping, and how to plan the phase after weight loss.
Read guideQuestions, answered.
Where do I start?
If you are new, open the beginner lessons in the Academy, then browse the compound library. If you already know what you are looking for, use the calculator or search for a compound by name.
What does a compound guide contain?
A plain-language overview, the research areas the compound is studied in, the evidence stage with its supporting sources, human, animal, and laboratory findings shown separately, the limitations and unanswered questions, linked references, and the date the page was last reviewed.
What does an evidence stage mean?
It describes the kind of research available — human randomized trial, other human research, animal, or laboratory. It never indicates that a compound is effective or safe, and animal or laboratory findings should not be read as expected human outcomes.
What does the calculator do — and what does it not do?
It converts a material amount, a final solution volume, and a target amount into a concentration and a target volume, with an optional U-100 scale reading. It never recommends a dose, schedule, or route of administration, and it is not medical advice.
Are the numbers I enter saved?
No. Every calculation runs in your browser. Entered amounts are never sent to analytics and are not stored on a profile. Browsing and calculating never require an account.
How are sources selected?
We cite published research, regulator documents, and testing-lab reports, and we link them so you can read the originals. Vendor marketing is never treated as evidence.
Is Wize Peptides independent?
We partner with various affiliate stores and may earn a commission on qualifying purchases made through links on this site. That relationship is disclosed wherever it appears and never influences what we publish.
Is any of this medical advice?
No. Everything here is for information and research purposes only. Nothing diagnoses, treats, cures, or prevents any condition.
