Description
Tamoxifen 10 mg Androlex — tamoxifen from Androlex at 10 mg. SERM with tissue-selective agonist/antagonist activity. Blocks breast-tissue estrogen receptors (gyno prevention) while acting as agonist at hypothalamus (driving LH/FSH for PCT).
Key Benefits
- SERM — selectively blocks estrogen at the breast tissue (no gyno)
- Does not lower systemic E2 (unlike AIs) — safer for lipids
- PCT workhorse — stimulates LH/FSH release via hypothalamic feedback
- Available as generic — reliably priced worldwide
- Standard dose 20 mg/day; PCT protocols 20–40 mg/day
- Each unit dosed at 10 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: on-cycle 10–20 mg/day for gyno prevention; PCT 20–40 mg/day for 4 weeks. Some researchers taper PCT: 40/20/20/10. Nolva alone is a valid PCT for mild-to-moderate cycles.
How It Works
Selective estrogen receptor modulator (SERM). Antagonises the estrogen receptor in breast tissue (prevents gyno) while acting as a partial agonist at the hypothalamus (stimulates LH/FSH release) and liver (maintains favourable lipids).
Pharmacokinetics
Plasma half-life approximately 5–7 days (active metabolite 14 days). Once-daily dosing. Long action tail — consider when planning PCT timeline.
Potential Side Effects
Mood effects possible (a minority of users experience depression/lethargy). Vision changes at high dose are rare but documented. No lipid hit. DVT risk in susceptible individuals on long runs.
Cycle & Stacking Guide
On-cycle: 10–20 mg/day if prone to gyno. PCT: 20–40 mg/day for 4 weeks, starting 14 days after last long-ester injection (or 3–5 days after short-ester). Often paired with Clomid for stronger LH stimulation.
Manufacturer Notes
Androlex is a Moldovan producer focused on injectable AAS at standard concentrations. Each vial carries a batch-traceable code verifiable through their distributor network.
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.
