Sustaplex 350 by AxioLabs is a potent testosterone blend designed for long-lasting anabolic action. It combines four different esters—Testosterone Propionate (42 mg), Testosterone Isocaproate (84 mg), Testosterone Phenylpropionate (84 mg), and Testosterone Decanoate (140 mg)—to provide both fast and sustained testosterone release.
This multi-ester composition helps maintain stable testosterone levels and is ideal for users seeking maximum muscle mass, strength, and recovery support.
Sustaplex 350 is commonly dosed at 350–700 mg per week, injected 2–3 times weekly to maintain stable hormone levels. It can be stacked with bulking agents like Decaplex 250 or Methanoplex for powerful synergistic results in size and strength.
As with any testosterone-based cycle, PCT is crucial. After discontinuing Sustaplex 350, run a proper PCT using agents like Clomiplex or Tamoxiplex to restore endogenous testosterone production.
Sustaplex 350 is used to increase testosterone levels, support lean muscle gain, enhance strength, and improve physical performance in bodybuilding and TRT research.
It is typically injected 2–3 times per week to maintain even hormone levels, due to its mixed ester profile.
