Description
P-BOL 10 mg Muscule Pharm — mesterolone from Muscule Pharm at 10 mg. Oral DHT derivative without 17α-alkyl toxicity. Strong SHBG displacement frees bound testosterone — cycle adjunct, not standalone anabolic.
Key Benefits
- Highest anabolic:androgenic ratio of any common AAS (~322–630 / 24)
- Does NOT aromatise — zero oestrogenic side-effects
- Minimally hepatotoxic relative to other 17α-alkylated orals
- Mitochondrial fatty-acid uptake enhancement — cutting utility
- One of few AAS with documented female protocols (5–20 mg/day)
- Each unit dosed at 10 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: men 20–80 mg/day split two or three times daily; women 5–20 mg/day single dose. Standard cycle 6–8 weeks. Above 80 mg/day gains plateau while liver-enzyme burden continues rising.
How It Works
17α-alkylated DHT-derivative with a modified A-ring that strips androgenic expression while keeping anabolic activity. Does not aromatise. Binds the androgen receptor with modest affinity; results come from elevated protein synthesis, mitochondrial fatty-acid uptake, and erythropoiesis rather than raw AR occupation.
Pharmacokinetics
Oral bioavailability ~97% — highest of any AAS. Plasma half-life approximately 9 hours; splitting the daily dose across 2–3 administrations keeps serum levels flat. Hepatotoxicity low relative to methylated orals but still real; pull ALT/AST at week 4.
Potential Side Effects
Lipid panel disruption (HDL drop) is consistent. Mild LH/FSH suppression even at low doses — mini-PCT appropriate after 6+ week cycles. No water retention, no oestrogenic effects. Androgenic sides (hair-thinning in susceptible users) possible at higher doses.
Cycle & Stacking Guide
Cutting adjunct on a testosterone base, 6–8 weeks. Stacks with test + masteron for pre-contest hardening or with clen + T3 for recomp. Often used as a finisher (final 6 weeks of a 14-week cycle). TUDCA 500 mg/day throughout.
Manufacturer Notes
Muscule Pharm produces standardised AAS oils with labelled pre-filled concentrations. Each SKU’s letter prefix denotes the ester family (T=testosterone, P=propionate, W=winstrol, etc.).
Storage & Handling
