Sustalab-250 represents a blend of 4 different esters of testosterones: Testosterone Decanoate, Testosterone Phenylpropionate, Testosterone Propionate and Testosterone Isocaproate.
Due to the fact that each of 4 testosterones posses different time release, Sustalab-250 is considered to have long term impact on blood levels, thus less injections are required. Usually most athletes injects it twice per week.
Sustalab-250 users may experience androgenic side effects such as acne, aggressiveness, sexual simulation, baldness). The water retention  doesn’t pass the normal limits and it is considered to be smaller than in cases of  using Enanthate or Cypionate.
