The negatives of SUST 300 A-Tech Labs

To make the most of all the beneficial effects of Sustanon, it is advisable to combine it with other injectable steroids like deca durabolin.

Our advice

  • We advise you to combine this with Deca Durabolin and Dianabol or Anabol for mass gain.
  • Sustanon and Deca can be mixed in the same syringe to make a single injection.
  • For a lean mass gain just add either primobolan or Winstrol.

SUST 300 is the “sure thing” of testosterone esters. Indeed, the diversity of the ester component allows Sustanon to act in several ways, both short term and long term. The presence of testosterone propionate achieves immediately results after intake while other esters ensure the maintenance of a high testosterone level over 4 weeks.

This diverse composition also allows the Sustanon to provide a satisfactory muscle mass gain with a qualitatively as well as quantitative perspective: the gains are not only important in mass and strength , but additionally transforms the acquired mass into denser and better quality mass than some testosterone esters that create more water retention. This is one of the reasons why the Sustanon is also popular in the middle of bodybuilding.

Many bodybuilders use SUST 300 in combination with Deca durabolin or Dianabol to achieve fast and significant gains in muscle mass. For better muscle gains, Sustanon is used with Primobolan, winstrol or Oxandrolone. It is often necessary to use an anti-estrogen like Nolvadex or Proviron to avoid gynecomastia, as well as Vitagon HCG or Clomid in cases of a cycle exceeding 6 weeks, in order to boost the natural production of testosterone in the testes as early as stopping the cycle.
