Key Benefits
- Dopamine D2 agonist — suppresses prolactin
- On-cycle support for nandrolone and trenbolone users
- Low-dose protocol 0.25 mg twice weekly
- Pull prolactin at week 6 to confirm dose adequacy
- Mood elevation and libido support are bonuses
- Each unit dosed at 50 mcg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 0.25 mg twice weekly for on-cycle prolactin control with deca or tren. Higher doses (0.5 mg 2×/week) for users with elevated baseline prolactin.
How It Works
Ergot-derived dopamine D2 receptor agonist. Suppresses pituitary prolactin secretion. Clinically used for hyperprolactinemia and Parkinson’s. In AAS protocols: counters the prolactin rise from progestagenic compounds (19-nors).
Pharmacokinetics
Plasma half-life approximately 63–69 hours. Twice-weekly dosing sufficient. Steady-state in 2 weeks.
Potential Side Effects
Nausea common initially — take with food. Orthostatic hypotension possible. High-dose long-term use carries cardiac valve concern (documented in Parkinson’s patients on 3+ mg/day — not at AAS-protocol doses).
Cycle & Stacking Guide
On-cycle support with nandrolone, trenbolone, or progestagenic orals (oxymetholone). 0.25 mg 2×/week throughout cycle. Bloodwork at week 6 — target prolactin <15 ng/mL.
Manufacturer Notes
Magnus Pharmaceuticals focuses on the research-chemical end of the market with detailed batch identifiers. Injectables use cotton-seed or grape-seed oil for reduced PIP.
Storage & Handling
Store in the original blister or bottle at 15–25 °C, away from direct sunlight, heat, and humidity. Oral preparations lose potency faster if exposed to moisture; keep the desiccant (if included) with the tablets. Keep out of reach of children. For research and educational purposes only.
