HCG 5000 IU Bio-Peptide

Description

HCG 5000 IU Bio-Peptide — human chorionic gonadotropin from Bio-Peptide at 5000 iu. LH-mimetic: directly stimulates leydig-cell testosterone production and spermatogenesis. On-cycle testicular maintenance or pre-PCT priming.

Key Benefits

• Human chorionic gonadotropin — mimics LH, stimulates testicular testosterone
• Prevents testicular atrophy on long cycles
• Used on-cycle (not during PCT — can desensitise receptors)
• Reconstituted with bacteriostatic water; SubQ or IM injection
• Standard on-cycle 250–500 IU 2× weekly
• Each unit dosed at 5000 IU — see Recommended Dosage below for protocol-specific intake

Recommended Dosage

Research dosing: on-cycle 250–500 IU 2× weekly SubQ to prevent testicular atrophy. Pre-PCT blast 1000 IU 2× weekly for 2 weeks. Not used during PCT proper — chronic HCG desensitises Leydig cells to LH.

How It Works

Human chorionic gonadotropin, a glycoprotein hormone with LH-like activity. Binds the LH receptor on testicular Leydig cells, stimulating testosterone production directly — bypasses pituitary suppression.

Pharmacokinetics

Plasma half-life approximately 33 hours. Twice-weekly SubQ dosing produces stable effect. Reconstituted vial stable in fridge for 30 days.

Potential Side Effects

Excessive dose raises E2 (testicular estrogen output) — pair with AI. Water retention possible. Chronic high-dose use desensitises LH receptors, hampering natural recovery.

Cycle & Stacking Guide

On-cycle protocol: 500 IU 2× weekly throughout the cycle to maintain testicular size and function. Stop 2 weeks before SERM-based PCT begins. Alternative: pre-PCT blast approach — skip during cycle, then 1000 IU × 2/week for 2 weeks before starting SERMs.

Manufacturer Notes

Bio-Peptide produces research peptides with published HPLC purity data. Lyophilised powder in amber-glass vials; reconstitute with bacteriostatic water before use.

Storage & Handling

Pre-reconstitution: store at 2–8 °C, protected from freezing and light. Post-reconstitution: use within 14–21 days, maintained at 2–8 °C throughout. Never freeze reconstituted solution — freezing irreversibly denatures the protein. Transport in an insulated cold-pack for trips. Keep out of reach of children.
