Masteron Enanthate 200mg/mL

A high-purity, oil-based injectable formulation of Masteron Enanthate (Drostanolone Enanthate) designed exclusively for laboratory, analytical, and research use. As a long-ester variant of drostanolone, it provides sustained androgenic signaling with minimal aromatization, making it a preferred compound in androgen receptor binding, lipid metabolism, and endocrine regulation studies.

Its unique combination of moderate anabolic activity and strong anti-estrogenic behavior makes it ideal for research focused on lean tissue preservation and metabolic modulation under varying androgenic environments.

Moderate anabolic, low androgenic profile:
Drostanolone exhibits roughly half the anabolic potency of testosterone but with minimal androgenic activity, allowing controlled modeling of androgen receptor dynamics.

Non-aromatizing compound:
As a DHT-derived anabolic, Masteron does not aromatize to estrogen—commonly used in comparative research on estrogen-dependent and estrogen-independent anabolic pathways.

Supports lipid and glucose metabolism research:
Drostanolone has been studied for its influence on HDL/LDL ratios, glucose utilization, and metabolic efficiency in preclinical models.

Extended-acting formulation:
The enanthate ester provides a long half-life of approximately 5–7 days, supporting sustained plasma concentrations and reduced administration frequency in longitudinal research designs.

Ideal for androgen receptor selectivity studies:
Frequently employed in in-vivo and in-vitro models investigating androgen receptor expression, muscle catabolism resistance, and hormonal homeostasis.

Our Masteron Enanthate 200 mg/mL delivers pharmaceutical-grade drostanolone in a controlled long-ester formulation—trusted in androgen receptor and endocrine function research requiring precision, stability, and verified purity.

• ≥99% purity verified via HPLC & Mass Spectrometry

• Long-ester profile with ~5–7 day half-life for sustained kinetics

• Sterile, oil-based injectable solution in tamper-evident vials

• Full COA (Certificate of Analysis) available upon request

• Discreet, tracked shipping for laboratory assurance

Once administered, Drostanolone Enanthate slowly hydrolyzes, releasing drostanolone—a 5α-reduced androgen structurally related to dihydrotestosterone (DHT). It binds strongly to androgen receptors, exerting anabolic effects without conversion to estrogen or progestin intermediates.

Its high receptor affinity and metabolic stability make it valuable for research across multiple domains:

• Androgen receptor selectivity and affinity modeling

• Anti-estrogenic and SHBG interaction studies

• Muscle preservation under caloric restriction or catabolic states

• Lipid metabolism and cardiovascular biomarker profiling

• Comparative analysis of DHT-derived vs testosterone-derived anabolics

Is Masteron Enanthate legal to purchase?
A: Our Masteron Enanthate is sold strictly as a research chemical and not for human consumption. Customers must ensure compliance with all applicable regulations in their jurisdiction.

What is the difference between Enanthate and Propionate esters?
A: The enanthate ester provides extended release and slower clearance (~5–7 days half-life), suitable for sustained exposure models. The propionate ester acts faster but requires more frequent administration.

Does it aromatize to estrogen?
A: No. Drostanolone cannot aromatize due to its DHT-based structure, making it ideal for studying estrogen-independent anabolic pathways.

What are typical effects in research models?
A: Studies have shown drostanolone increases nitrogen retention, supports muscle fiber density, and may improve lipid ratios by reducing total cholesterol and triglycerides under certain conditions.

What if crystallization occurs in the vial?
A: Warm gently (no higher than 37 °C) and swirl until dissolved. If discoloration or visible particulates remain, do not use.

Can it be combined with other compounds for comparative research?
A: Yes. In research contexts, drostanolone is frequently studied alongside testosterone esters or DHT analogues to examine combined effects on receptor occupancy, protein synthesis, and metabolic outcomes.

Are there known side effects in human data?
A: Human data indicate potential for androgenic effects (acne, hair thinning, voice deepening in females) and lipid profile alterations.
