Primobolan Enanthate (Depot) 100mg/ml

A high-purity, oil-based injectable formulation of Primobolan Enanthate (Methenolone Enanthate) designed exclusively for laboratory, analytical, and research use.

This long-ester anabolic compound is prized in research models for its stable anabolic profile, low androgenic expression, and minimal aromatization, making it ideal for studies examining muscle preservation, nitrogen retention, and metabolic efficiency under various hormonal conditions.

Mild anabolic, low androgenic ratio:
Methenolone demonstrates a favorable anabolic-to-androgenic index, enabling investigation of lean-tissue maintenance without confounding virilizing effects common to stronger androgens.

Non-aromatizing profile:
Primobolan does not convert to estrogen, making it valuable in comparative studies isolating pure androgen-receptor-mediated effects on muscle and bone tissue.

Long-acting enanthate ester:
Provides a sustained release curve (half-life ≈ 7 – 10 days), supporting long-term studies with infrequent administration schedules.

Supports metabolic and nitrogen-balance research:
Used in preclinical settings to study protein synthesis, anti-catabolic activity, and lipid metabolism modulation.

Ideal for dose-response and receptor-specific assays:
Because of its mild action and clean pharmacokinetic profile, it’s often chosen for controlled comparative androgen research.

Our Primobolan Enanthate 100 mg/mL delivers pharmaceutical-grade Methenolone Enanthate in a sterile oil-based formulation, verified for structural integrity and purity to support advanced anabolic-androgenic studies.

• ≥ 99 % purity verified via HPLC & Mass Spectrometry

• Long-ester profile providing stable plasma kinetics for 7 – 10 days

• Sterile, tamper-evident vials for safe laboratory handling

• Full COA (Certificate of Analysis) available upon request

• Discreet, tracked shipping for institutional assurance

After administration, Methenolone Enanthate gradually hydrolyzes, releasing Methenolone, a DHT-derived anabolic that binds selectively to androgen receptors.

It promotes nitrogen retention, protein synthesis, and reduced glucocorticoid activity, all of which are critical in muscle-preservation and catabolic-resistance models.

Research applications include:

• Androgen receptor selectivity and transcriptional activity studies

• Comparative anabolic vs androgenic potency evaluations

• Skeletal-muscle protein turnover investigations

• Catabolic suppression and metabolic-rate modeling

• Erythropoietic stimulation and oxygen-utilization studies

Is Primobolan legal to purchase?
A: This product is sold strictly as a research chemical, not for human use or consumption. Researchers are responsible for compliance with local laws and regulations.

What is the half-life of Primobolan Enanthate?
A: Approximately 7 – 10 days, providing a long-acting kinetic curve ideal for extended in-vivo or in-vitro studies.

How does it compare to Testosterone Enanthate?
A: Primobolan shows lower androgenicity and zero aromatization, allowing studies focused on anabolic mechanisms independent of estrogenic or strong androgenic variables.

What physiological effects are typically observed in research?
A: Enhanced nitrogen retention, increased lean-tissue integrity, improved RBC count, and stable lipid metabolism parameters, depending on study design.

Can it be stacked with other compounds for research?
A: Yes. In comparative protocols, it’s often combined with Testosterone Enanthate, Nandrolone Decanoate, or non-aromatizing anabolics to assess synergistic or antagonistic interactions.

What if crystallization occurs in the vial?
A: Warm gently (not above 37 °C) and swirl until dissolved.
If discoloration or particulate matter persists, do not use.

What side effects are documented in human data?
A: Human findings (for reference only) indicate possible suppression of endogenous testosterone, lipid-profile alterations, and mild androgenic effects at high exposure.
