Test base is the undisputed king of steroids mainly because it is safe, elicits rapid mass and strength gains while maintaining libido, a sense of well being and energy. It's not uncommon for a first time user to gain 15-20lbs of LBM in a standard Testosterones cycle. Pure Testosterones comes in a water based aqueous form (Suspension) and also in a solvent/oil based form (Test Base).

Suspensions have tiny particles that are visible with the naked eye. If left on the shelf for a few days many times the particles will sink to the bottom leaving the clear solvents and water on the top. Depending on the manufacturer, particle sizes vary meaning some Suspension preparations can clog a 22 gauge needle. Ultra micronized Suspension can pass through a 25 gauge needle making injections more comfortable. Shake the suspension preparation vigorously before injecting.

Testosterones Base is the most common anabolic hormone that there is and is also considered the most basic. Due to this, bodybuilders often consider it the base steroid to most all cycles. Testosterones Base is both anabolic and androgenic in nature. Users of this steroid will notice a dramatic gain in muscle size and strength, as well as an overall sense of well being and increases libido and sex drive.


Testosterones Suspension is an injectable Testosterones hormone in a water base that was developed and used for decades, and is actually the first anabolic androgenic steroid made. For the purpose of building mass, Testosterones Suspension has never been surpassed since it was first developed in the 1930s. Many underground labs also suspend this product in propylene glycol or oil as well (which makes for a very painful injection). It has no ester attached; therefore no ester is calculated into the weight.
