Mastaplex 100 by Axiolabs is a fast-acting injectable steroid containing 100mg/ml of Drostanolone Propionate—commonly known as Masteron Propionate. It is a DHT-derived anabolic ideal for cutting, recomposition, or contest prep cycles, especially for users seeking aesthetic muscle hardness and dryness.
Drostanolone Propionate is also known for its anti-estrogenic properties, making it a natural support compound in cycles that involve aromatizing agents like Testosterone. It delivers visual enhancements, making muscles look grainy, dense, and vascular—perfect for the stage or photo-ready conditioning.

Mastaplex is considered mild and well-tolerated, especially in comparison to stronger anabolic steroids. Still, potential side effects may include:
Mild androgenic effects: acne, hair thinning, oily skin
Suppression of natural testosterone (especially in longer cycles)
Joint dryness (common in lean compounds)
Cholesterol imbalance (monitor HDL/LDL)
β Does not aromatize, so no estrogenic side effects like gyno or water retention.
Do not use if you have DHT-sensitivity, prostate issues, or cholesterol disorders
Should always be combined with a Test base to avoid suppression-related libido issues
Monitor lipid profile, especially in long or stacked cycles
Not suitable for women at high doses (virilization risk)
Excessive dosing may result in:
Hair loss or acne (androgenic overload)
Severe suppression of natural testosterone
Reduced HDL ("good" cholesterol)
Mood swings or irritability
β Stay within the clinical range, use on-cycle support, and complete a full PCT.
Week | Expected Results |
---|---|
Week 1–2 | Improved muscle tightness, early dryness |
Week 3–4 | Vascularity and strength begin increasing |
Week 5–6 | Peak definition, visible hardening |

Q: Is Mastaplex 100 good for bulking?
β Not ideal. It's a cutting and physique refinement compound, not meant for mass-building.
Q: Does it aromatize or cause gyno?
β
No. Drostanolone does not convert to estrogen, so there's no water retention or estrogenic side effects.
Q: Should I run PCT after a Mastaplex cycle?
β
Yes. It can suppress natural testosterone, especially when stacked. Use Clomid/Nolvadex post-cycle.
Q: Is it safe for women?
β οΈ At very low doses and short cycles. However, the risk of virilization remains high.
Q: How soon do results show?
π You'll feel tighter and harder in 1–2 weeks, with visual results peaking by week 6–8.
