Medical disclaimer

This is not medical advice

Nothing in the PepCycle app or on this website constitutes medical advice, diagnosis or treatment. The content here is general and educational. It is not tailored to any individual, cannot account for your medical history, medications, allergies or circumstances, and must not be used as a substitute for consultation with a qualified healthcare professional.

Never disregard professional medical advice, or delay seeking it, because of something you read here. If you think you may have a medical emergency, contact your local emergency services immediately.

We do not provide dosing information

You will not find a recommended dose, a starting dose, a maximum dose, a titration schedule, a cycle length or a stack protocol anywhere on this site or in the app. This is deliberate and absolute.

• For unapproved compounds, there is no established human dosing to report. Publishing a figure would present a guess with unearned authority.
• For approved medicines, dosing is defined by the approved prescribing information and applied by a prescriber who knows your situation. Reproducing schedules invites people to follow them without one.

Where a number does appear — “commonly supplied as 5 mg vials” — it is a fact about product packaging, included because it is what the arithmetic requires, not a suggestion about quantity.

What the calculators are

The calculators on this site, and the converter in the app, perform deterministic arithmetic on values you enter. Mass divided by volume gives a concentration; amount divided by concentration gives a volume; volume multiplied by a syringe's calibration gives a unit reading. That is the whole of it.

They contain no database of compounds, no dosing tables and no logic that varies by substance. They do not know what you are calculating for, and they cannot tell you whether a number you entered is appropriate. Verify every result against your own vial label and the instructions you were given.

Regulatory status and legality

Many compounds described on this site are not approved for human use in the United States, European Union, United Kingdom or elsewhere. Some are sold under a “research use only” designation, some are prohibited in tested sport, and some are restricted from pharmacy compounding. Legal status varies by country and changes over time.

Describing a compound is not an endorsement of obtaining or using it, and nothing here should be read as encouragement to do either. We publish no vendor information, no sourcing guidance and no affiliate links, and we have no commercial relationship with any supplier of any substance described on this site.

Accuracy and currency

We take accuracy seriously and review pages periodically, with the review date shown on each. Even so, regulatory positions, product presentations and scientific understanding change. No warranty is given that any page is complete, current or error-free.

If you believe something here is wrong, please tell us — corrections are genuinely welcome and we will fix them.

Your responsibility

Decisions about what you take, in what quantity and on what schedule are yours, and are best made with a licensed healthcare provider who knows your history. By using this site or the app you acknowledge that PepCycle is a record-keeping tool and accept that responsibility for those decisions rests with you and your clinician.
