What is T-400?

Synthetic testosterone was developed in the early 1930’s and has since become one of the most commonly used anabolic steroids to primarily treat low testosterone in males. T-400 is a high concentration blend of 4 of the most common esters: 100mg Testosterone Enanthate, 100mg Testosterone Cypionate, 100mg Testosterone Decanoate, and 100mg Testosterone Propionate. This allows users the ability to perform less frequent injections while still maintaining a high dose of Testosterone.

T-400 is a popular and versatile blend of testosterone that is an excellent mass-building steroid commonly used by bodybuilders and athletes looking to improve strength and gain lean muscle mass. The propionate ester allows for this blend to be quick acting, while the other three esters allow for a continued steady release of the active hormone into the body, lasting up to 15 days. It is the perfect blend for quick yet long-lasting results, with more stable blood-hormone levels and less mood swings. As with all esters of Testosterone, it carries an anabolic/androgenic rating of 100/100, respectively, and is not recommended for use in females.

T-400 offers the same considerable health benefits of the single-ester varieties, that far outweigh the potential side effects. These benefits include: enhanced protein synthesis and nitrogen retention, increased red blood cell count, increased IGF-1 output, and increased strength gains and muscular endurance to name a few. Effects from T-400 are often felt immediately due to the short half-life of the propionate ester in the suspension, however, it is recommended that a full cycle of at least 8-12 weeks is obtained.

What is the recommended dosage?

The recommended dosage of T-400 varies widely depending on who you talk to. In our opinion, a sensible dosage for most athletes is between 400-1200mg per week. Although T-400 carries a higher concentration of the active hormone, it is recommended that this dose be divided into two injections per week to maintain optimal blood plasma levels.

A typical cycle will last 8-12 weeks, with a maximum of 20 weeks at higher dosages.

What does T-400 stack well with?

It is recommended that T-400 be added to any stack due to its considerable benefits. It stacks well with just about any injectable, oral, or combination thereof, and is the most common base used in both cutting and bulking cycles. It is highly recommended to use an estrogen blocker/aromatase inhibitor with all testosterone varieties.

For mass, size, and strength gains, try adding T-400 to another injectable such as: Deca Durabolin, Equipoise, Masteron Enanthate, NPP, Primobolan, or Trenbolone Enanthate.

For extreme results, try supplementing T-400 with an injectable listed above, as well as an oral steroid such as: Dianabol, Turinabol, Anadrol, Anavar, or Winstrol.
