One hundred tablets of 2 mg each, on a molecule that keeps working for two to three days after each dose, which is why the label schedule is twice a week rather than daily. The 2 mg strength is far above the 0.5 mg pharmacy tablet used for prolactin, so splitting the pill accurately becomes part of the protocol. This is a prescription medicine offered for research reference, not a cycle product, and it does nothing for estrogen.

Product Overview

Buy Cabergoline by Zyvex Pharmaceuticals at Best Anabolic Steroids. The unit is a single carton of one hundred white tablets, 2 mg apiece, and the active substance is an ergot-derived agonist at the dopamine D2 receptor. Agonists of this receptor tell the pituitary to release less prolactin, which is the whole point of the product and also the reason it is a prescription medicine rather than a support tablet in the ordinary sense.

Two strengths exist in pharmacy and they are not interchangeable. Cabaser, used in Parkinson disease, is the 2 mg product. Dostinex, used for raised prolactin, is 0.5 mg, and the approved ceiling for that indication is 1 mg twice a week. The Zyvex box carries the higher strength, so anyone working from a label schedule has to divide a tablet into halves or quarters, and a split that lands anywhere will move the true dose by a large fraction. A pill cutter and a fixed routine matter more here than on almost any other product in the catalogue.

Raised prolactin is not a cosmetic problem. It suppresses gonadotropin release, so libido, morning erections, mood and semen quality fall away while the number climbs, and it can produce tenderness or a small amount of fluid from the nipple. Nineteen-nor compounds are the usual suspect in a bodybuilding context, which is why this page sits beside the Nandrolone Esters and Trenbolone Esters cards rather than beside the mass builders.

Dosage Protocol

The rows below are the approved titration from the prescription label, quoted so that the figures in the literature make sense. They are not a schedule for a self-directed course, and no confirmed non-medical protocol exists.

Level	Amount	Length	Note
Starting step	0.25 mg twice weekly	Titration	Label starting dose, raised in 0.25 mg steps with at least four weeks between them
Middle step	0.5 mg twice weekly	By indication	The ordinary pharmacy strength, reached only if the first step does not hold the number
Upper step	1 mg twice weekly	By indication	The maximum the label allows, and the point where monitoring stops being optional
Female	Not confirmed	-	No safe non-medical protocol appears in the sources
Route	Oral tablet	Scheduled	The long half-life supports one or two doses a week, which is why accurate splitting matters

Pharmacokinetics explain the rhythm. Healthy volunteers clear the molecule with a half-life of 63 to 69 hours, and modelling in patients with raised prolactin returns figures from 79 to 115 hours. Nothing in the day-to-day level swings much once a dose is established, so there is no benefit in taking it more often, and a doubling of frequency simply doubles the exposure.

Suggested Protocols

Prolactin control is a single, narrow job. The arrangements below come from user practice and from the literature on nineteen-nor cycles; none of them is an approved indication.

Prolactin beside a converting course

Cabergoline - 0.25-0.5 mg, only on a reading + Testosterone Esters - the base that keeps the axis busy

Started after a prolactin result rather than at the opening of the course, and stopped when the number is back inside range

Two sides of the same symptom

Cabergoline - prolactin arm + Arimidex - estrogen arm, a different hormone

Nipple symptoms can come from either hormone, so the two are read separately instead of being treated as one target

Androgen support while the number settles

Cabergoline - prolactin only + Proviron Mesterolone - free androgen support + Aromasin - the alternative estrogen step

A card arrangement rather than a tested stack; the products sit on different pathways and are judged by different labs

What to Expect

Prolactin falls over weeks, not days. Long-term therapy normalises the figure in a share of patients, and the curve is slow in both directions.
Libido and morning erections are usually the first things to return when the number was genuinely high, because the pituitary brake on gonadotropins loosens.
Nothing about training changes. This molecule builds no tissue, adds no strength and has no anabolic action of any kind.
Nipple tenderness and discharge improve if prolactin was the driver; if estrogen is the driver, the answer sits elsewhere on the page.
Tolerability is front-loaded. Nausea, headache and dizziness cluster in the first days and after each step up, then settle.
A number that stays high on treatment is a referral question, not a reason to raise the dose. Pituitary imaging is the medical next step.

Side Effects and Management

Nausea, headache, dizzinessMost common early and after a step up; food, water and a slower ladder reduce it.

Orthostatic hypotensionStanding up too fast brings it on; check pressure and keep the steps small.

Constipation and fatigueManageable with fluid, fibre and sleep, and usually dose related.

Cardiac valve fibrosisDose dependent and mostly seen at the high daily doses used for Parkinson disease; the label asks for an echocardiogram before treatment and every 6 to 12 months.

Pleural and peritoneal fibrosisRare serious reactions; unexplained breathlessness or abdominal swelling needs a doctor.

Impulse control changesReported for dopamine agonists as a class; stop and seek review at the first sign.

Cumulative exposure is the variable that matters for the valve risk, with a figure near 300 mg of total dose quoted in prolactinoma data as a safety landmark. Split evenly, the 2 mg box here represents about a year of 0.5 mg twice-weekly dosing, so the arithmetic of a long plan is worth doing before the first tablet rather than later.

Post-Cycle Therapy and Axis Recovery

This product is not a recovery drug. Cabergoline does not raise luteinising hormone the way a SERM does, so it cannot replace Clomid Clomiphene or Nolvadex Tamoxifen after a suppressive course. Where it is discussed in the recovery context, the mechanism is indirect: if prolactin was the brake on the axis, removing that brake lets the natural signal recover on its own.

OnsetProlactin moves over two to four weeks, so the first check belongs after that, not on day three

Recovery stepNot applicable as a standalone PCT; the SERM stage belongs to the course that caused the suppression

Option ATamoxifen or clomiphene for the axis, cabergoline only if prolactin is confirmed high

Option BReducing the nineteen-nor load instead of adding a second dopamine agonist

Follow-upProlactin, total testosterone and LH/FSH together, read by a clinician, plus the cardiac monitoring the label requires

What is in the Zyvex Cabergoline box?

One hundred tablets, each 2 mg of cabergoline, an ergot-based agonist that acts on the dopamine D2 receptor. It is a prescription molecule approved for raised prolactin from an unknown cause or from a pituitary adenoma, and in sports practice it is discussed only as a way to bring that hormone down. It has no anabolic action and no effect on estrogen.

Why is this tablet 2 mg when pharmacy cabergoline is 0.5 mg?

The 2 mg strength belongs to the Cabaser product used in Parkinson disease. The prolactin product, Dostinex, is 0.5 mg, and the approved ceiling for raised prolactin is 1 mg twice a week. Working from a label schedule on this box therefore means quartering a tablet, and the accuracy of that split changes the real dose considerably.

How is cabergoline scheduled for prolactin?

The label opens at 0.25 mg twice a week and raises the amount in 0.25 mg steps no faster than every four weeks, with 1 mg twice a week as the top of the range. Because the half-life runs from 63 to 69 hours in healthy volunteers, a twice-weekly rhythm holds a steady level and more frequent dosing only increases exposure.

How quickly does prolactin come down?

Weeks rather than days. Normalisation is reached in a proportion of patients on long-term therapy and the effect builds gradually, which is why a test taken a few days after the first tablet proves nothing. The practical check sits two to four weeks in, and the answer decides whether anything changes at all.

Does it replace an aromatase inhibitor?

No. Prolactin and estradiol are separate hormones with separate control points. An inhibitor such as Arimidex works on the enzyme that makes estrogen, while cabergoline works at the pituitary on prolactin. Swapping one for the other because the symptom looks similar leaves the actual driver untouched.

Which side effects deserve the most attention?

Nausea, headache, dizziness and a drop in blood pressure on standing are common and mostly fade. The serious concerns are rare and dose dependent: fibrotic changes on heart valves, which is why the label asks for an echocardiogram before treatment and every 6 to 12 months, plus pleural or peritoneal fibrosis and impulse control disorders reported across the dopamine agonist class.

Is cabergoline useful after a cycle?

Only indirectly. It does not raise luteinising hormone and cannot stand in for a SERM, so the recovery stage after a suppressive course still belongs to Nolvadex Tamoxifen and clomiphene. Its contribution is limited to clearing a prolactin elevation that was holding the axis back, and that case needs a laboratory result before it is assumed.

Can it be taken without a doctor?

It is a prescription medicine with cardiac monitoring written into the label, and the 2 mg strength makes self-directed dosing awkward because every effective amount is a fraction of a tablet. A persistently high prolactin has causes that treatment does not fix, including pituitary adenoma, and those belong in front of a physician rather than on a tablet organiser.
