The bottom line No known interaction

We found no known interaction between Cyanostane and Lisdexamfetamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Cyanostane and Lisdexamfetamine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lisdexamfetamine and Cyanostane in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Cyanostane at all — not against Lisdexamfetamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From the ADVERSE REACTIONS section of the FDA label for Lisdexamfetamine. Read the label on DailyMed › Cyanostane’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cyanostane side to compare — that is a limit of the record, not a statement that Cyanostane has no side effects.

Special populations

Cyanostane in Pregnancy & Breastfeeding

Pregnancy And Lactation Possibly Unsafe

When used orally. Prohormones can be converted to active hormones in the body and cause adverse effects such as menstrual irregularities, infertility, hair loss, and acne. Prohormones have also been associated with hepatotoxicity and increased risk of cardiovascular disease. The U.S. Food and Drug Administration and other regulatory agencies warn that dietary supplements containing prohormones are dangerous. Avoid using.

Overlapping uses

What Lisdexamfetamine Is Prescribed For, and What Cyanostane Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Lisdexamfetamine is a prescription medicine with approved uses on its FDA label. Cyanostane is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Lisdexamfetamine is prescribed for: Lisdexamfetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in adults and children age 6 and older. It is also approved to treat moderate to severe binge eating disorder (BED) in adults. It is not approved or recommended for weight loss, and its safety and effectiveness for treating obesity have not been established. It is not recommended in children under 6 years old.

Cyanostane has been studied for:

  • Obesity studied, not established Cyanostane has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Cyanostane for obesity

    Although there is interest in using cyanostane for weight loss, there is insufficient reliable information about the clinical effects of cyanostane for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Lisdexamfetamine on your own; if you are taking Cyanostane for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Cyanostane

What is Cyanostane?

  • Muscle building
  • Strength gains
  • Body recomposition
  • Athletic performance

Cyanostane (often sold as 'Cyanostane Rx') is not a true dietary supplement or herb — it is marketed as a so-called 'prohormone' or designer anabolic steroid product. These products are not approved as supplements, may be illegal, and carry real risks of liver and hormonal harm, so we cannot recommend their use.

Tablets, capsules (sold as a bodybuilding 'supplement')

An interaction check asks whether these two react with each other — it does not ask whether Cyanostane is a good idea for someone in your situation. Here is what our Cyanostane record says about it on its own.

Cyanostane: dosing

There is no established, safe, or recommended dose for Cyanostane because it is not an approved supplement or medicine. A health professional can help you understand the risks and check on your liver and hormone health.

Taking Cyanostane and Lisdexamfetamine Together: Common Questions

Is it safe to take Cyanostane with Lisdexamfetamine?

Are Cyanostane and Lisdexamfetamine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Cyanostane in each. That is a conversation for your prescriber, especially if Lisdexamfetamine is being adjusted to a target.
Does Lisdexamfetamine interact with any supplements?
Yes. Lisdexamfetamine has documented interactions with 126 supplements in our database — Cyanostane is not one of them. The Lisdexamfetamine interaction page linked on this page lists every one, ranked by severity.
