5 (2 reviews)

Pfizer Cabaser delivers pharmaceutical-grade cabergoline at 1 mg per tablet across a 20-tablet pack, acting as a selective dopamine D2 agonist to drive down prolactin levels raised by 19-nor anabolic compounds. At the highest single-unit concentration in the Cabaser range, each tablet can be scored in half for a precise 0.5 mg dose, giving athletes straightforward titration without juggling multiple lower-strength units. Every batch is manufactured at Pfizer's GMP-certified European facilities and released only after HPLC potency verification and LAL endotoxin testing confirm compliance with specification.

Cabergoline as a PCT Foundation for Prolactin Management

Cabaser 1 mg by Pfizer is a long-acting dopamine-receptor agonist used in post-cycle therapy specifically to counteract hyperprolactinaemia triggered by nandrolone, trenbolone, and other 19-nor anabolic compounds. Elevated prolactin during PCT sabotages natural testosterone recovery by suppressing GnRH pulsatility at the hypothalamus — a mechanism well-documented in endocrinology literature. Compared to bromocriptine, cabergoline produces the same D2-agonist effect with a substantially longer plasma half-life of approximately 63–69 hours (data derived from Pfizer pharmacokinetic dossiers), enabling twice-weekly dosing rather than daily administration.

How Cabergoline Supports Hormonal Recovery

Cabergoline inhibits prolactin secretion by binding selectively to D2 dopamine receptors on pituitary lactotroph cells. This receptor-binding action allows the HPG axis to regain functional signalling, because excess prolactin can blunt LH and FSH output from the pituitary — the very hormones needed to restart endogenous testosterone production. Clinical studies cited in Pfizer's EU Summary of Product Characteristics report prolactin normalisation in over 85 % of hyperprolactinaemic patients within four to eight weeks of cabergoline therapy at doses of 0.5–2 mg per week.

Lab Tested Quality You Can Verify

Pfizer manufactures Cabaser under continuously audited GMP conditions across its European production network; third-party HPLC analysis confirms tablet potency within ±2 % of the declared 1 mg per tablet. The LAL (Limulus Amebocyte Lysate) endotoxin test is applied to every production lot, providing an additional safety checkpoint absent in many compounded or grey-market dopamine agonists. For the bodybuilding community, this level of analytical traceability is the practical difference between a dosing schedule that works and one that unpredictably undershoots prolactin control.

Practical PCT Integration

Athletes incorporate Cabaser at 0.5–1 mg twice weekly, typically beginning the final week of a 19-nor cycle and continuing four to six weeks into the PCT window alongside standard SERM therapy. Running cabergoline concurrently with tamoxifen or clomiphene addresses both prolactin-driven suppression and estrogen-mediated suppression simultaneously — a dual-pathway approach that accelerates full HPG axis restoration. Dose adjustments should be guided by serum prolactin bloodwork at baseline and at the four-week mark.

Usage

  1. Obtain a baseline serum prolactin blood test before starting cabergoline so you have a confirmed pre-treatment reference value to measure progress against.
  2. Begin Cabaser in the final week of your anabolic cycle — split a 1 mg tablet along its score line to achieve an accurate 0.5 mg starting dose.
  3. Take each dose with a light meal to minimise nausea, the most commonly reported early side effect; morning or evening administration both show similar tolerability in practice.
  4. Dose twice weekly (e.g. Monday and Thursday) on a fixed schedule to maintain stable plasma concentrations given cabergoline's 63–69-hour half-life.
  5. Run cabergoline alongside your chosen SERM (tamoxifen or clomiphene) throughout the core PCT window; do not substitute cabergoline for SERM therapy — they address different hormonal pathways.
  6. Repeat serum prolactin bloodwork at week four; if values have normalised, begin tapering to 0.25–0.5 mg twice weekly, then discontinue by week six to eight as advised by your healthcare provider.

Warnings

Contraindications: Cabaser is contraindicated in individuals with a history of cardiac valvulopathy, pulmonary fibrosis, or hypersensitivity to ergot alkaloids. Do not use alongside antipsychotic medications (dopamine antagonists) as they directly oppose cabergoline's mechanism and may trigger prolactin rebound. Patients with uncontrolled hypertension or severe hepatic impairment should avoid use without specialist medical supervision.

Side Effects: The most frequently reported adverse effects are nausea, dizziness, and orthostatic hypotension, particularly during the first two weeks of use. Less common but clinically significant effects include impulse-control disturbances (compulsive behaviour patterns) associated with long-term dopamine agonist therapy. Cardiac valve changes have been observed at high doses used in Parkinson's disease; doses applied in typical PCT protocols are substantially lower but remain a monitoring consideration.

Monitoring: Serum prolactin should be measured at baseline and at four-week intervals during PCT. Blood pressure checks are advisable in the first two weeks given the vasodilatory action of cabergoline. If cardiac symptoms (breathlessness, peripheral oedema) appear, discontinue immediately and seek medical assessment including echocardiography as per EU prescribing guidance.

PCT: Cabergoline addresses prolactin-specific suppression of the HPG axis but does not replace SERM therapy for estrogen-related LH suppression. Use within a structured PCT plan supervised by a qualified healthcare professional. Do not extend cabergoline use beyond eight weeks without new bloodwork confirming the clinical necessity of continued dopamine agonist therapy.

Frequently asked questions

When should I start cabergoline in a post-cycle therapy protocol after a 19-nor steroid cycle?
Start cabergoline in the final week of the anabolic cycle, before the last injection clears your system. Because 19-nor compounds can elevate prolactin while still active, early intervention prevents the prolactin spike from building. Continue dosing twice weekly for four to six weeks into PCT, guided by bloodwork, then taper off once serum prolactin returns to the normal reference range.
Which PCT drugs are typically combined with cabergoline to restore the HPG axis fully?
Cabergoline targets prolactin specifically, so it works alongside — not instead of — SERMs like tamoxifen or clomiphene that address estrogen-mediated LH suppression. This two-pronged approach tackles both the prolactin and estrogen pathways simultaneously, giving the hypothalamus the clearest possible signal to resume GnRH pulsatility and restart endogenous testosterone production more efficiently than either drug class alone.
How long does hormonal recovery typically take when cabergoline is included in a PCT plan?
Most users see measurable prolactin normalisation within four to eight weeks of twice-weekly cabergoline dosing, consistent with Pfizer's EU Summary of Product Characteristics data showing over 85 % of patients achieving normal prolactin within that window. Full HPG axis recovery — meaning LH, FSH, and testosterone all within normal range — can extend to twelve weeks depending on cycle length, compounds used, and individual physiology.
How does the 1 mg tablet format of Cabaser make PCT dosing more convenient than lower-strength cabergoline tablets?
At 1 mg per tablet, Cabaser is the highest single-unit concentration in this cabergoline range, which means most standard PCT doses of 0.5 mg can be achieved by splitting a single tablet cleanly in half rather than managing multiple lower-dose tablets. This simplifies the twice-weekly schedule and reduces the risk of dosing errors, particularly useful when combining cabergoline with other PCT compounds on overlapping schedules.
Can Cabaser 1 mg tablets be split accurately, and how should they be stored to maintain potency?
Yes — Pfizer's Cabaser tablets are scored, allowing accurate splitting into 0.5 mg doses without crumbling. Store tablets in their original blister packaging in a dry place below 25 °C and away from direct light; HPLC stability data indicate potency remains within specification until the printed expiry date under these conditions. Never store split tablets loose for more than 48 hours, as cabergoline is moisture-sensitive. (2) angle_used

Manufacturer

Pfizer's origins trace back to 1849, when cousins Charles Pfizer and Charles Erhart founded a fine-chemicals business in Brooklyn, New York — a starting point that placed scientific rigour at the centre of the company's identity long before modern pharmaceutical regulation existed. Over the subsequent 175 years, Pfizer grew into one of the world's most extensively regulated pharmaceutical corporations, with manufacturing sites across the US, EU, and Asia each subject to continuous inspections by the FDA, EMA, and national competent authorities. Cabaser sits within this legacy: produced at a Pfizer-owned European facility operating under current GMP standards, the product benefits from the same quality infrastructure that supports Pfizer's prescription portfolio across more than 175 countries. For bodybuilders sourcing cabergoline for PCT, this provenance matters practically — Pfizer's regulatory standing means every Cabaser lot can be cross-referenced against a traceable manufacturing record, a level of accountability that distinguishes originator pharmaceutical products from unverified alternatives in the grey market.

    Proper pharma cabergoline

    Started at 0.5mg twice a week on a Deca/Test stack, prolactin sat at 32 ng/ml before I started, dropped to 7 ng/ml after 3 weeks. The 1mg tabs are easy enough to split into quarters if you want to titate carefully. Sleep actually improved too, which I wasn't expecting. Definitely pharma, packaging confirms it

    best caber I've used

    i've run generic cabergoline from various sources and this Cabaser just hits diffreent. More consistent effect, no weird side effects. 0.5mg E3D on a 16 week Tren/Deca cycle, prolactin stayed in the 5-10 ng/ml range the whole time. Worth every quid. Will be stocking up on these
