Mastaplex 100 by Axiolabs contains 100 mg/mL of fast-acting Drostanolone Propionate, a DHT-derived injectable anabolic steroid renowned for its physique-hardening properties. Popular among competitive bodybuilders and lean-focused athletes, this compound enhances muscle density, reduces water retention, and improves vascularity without estrogenic side effects.
Drostanolone, also known as Masteron, is derived from dihydrotestosterone (DHT). Its structure prevents conversion to estrogen via aromatase, making it an excellent choice during cutting cycles or pre-contest preparation. It works by promoting hard, dry muscle gains, enhancing definition, and providing mild androgenic effects without the bloat or gynecomastia risk seen with other compounds. A review of anabolic steroids confirms DHT-derivatives like Masteron are well-tolerated and effective for body recomposition.
Mastaplex is often injected EOD (every other day) to maintain stable blood levels. Its effects are maximized in users with low body fat, where its muscle-hardening benefits become visually pronounced. Many athletes pair it with Stanoplex 10 or Oxandroplex 10 to further amplify dryness and vascularity during the final weeks before a show.
Mastaplex 100 stacks exceptionally well in both contest prep and lean recomp cycles. Common stacks include:
Due to its mild androgenic profile, Masteron is often used as a balancing agent within harsh stacks—providing definition and anti-estrogenic synergy without harsh sides.
Since Mastaplex does not aromatize, estrogen-related side effects like bloating, gynecomastia, and water retention are not a concern. However, androgenic side effects can still occur, including:
No aromatase inhibitor is required during a solo Mastaplex cycle. However, if stacking with aromatizing compounds like Testosterone Enanthate, anti-estrogens such as Letroxyl or Aromaxyl are recommended.
Mastaplex 100 suppresses natural testosterone production and requires appropriate PCT. Begin your PCT around 3–5 days after the final injection:
If stacked with harsher suppressive compounds, consider adding hCG toward the end of your cycle to aid testicular recovery.
Serious athletes and contest-prep professionals can now find this premium Axiolabs version through a trusted supplier offering fast USA delivery and discreet packaging. It remains one of the most popular hardening agents in elite cutting stacks.
Mastaplex 100 offers elite-quality Drostanolone Propionate for those seeking the ultimate edge in physique hardening, dryness, and vascularity.

Whether used solo or in a cutting stack, Axiolabs Mastaplex provides predictable, quality results.
Yes. Drostanolone Propionate is ideal for cutting and contest prep, as it enhances definition, reduces water retention, and helps create a dry, hard look.
No, Mastaplex 100 does not aromatize. However, if stacked with aromatizing compounds like testosterone, an AI such as Letroxyl is recommended.
Due to the propionate ester, most users notice effects within 7–10 days, including improved hardness, strength, and vascularity.
It is not recommended for women due to the risk of virilization. Other milder options like Oxandrolone may be considered for female athletes.
