Suspension is the oldest steroid ever created. Basically it is pure testosterone without any ester attached to it. This has its disadvantages because without any ester the testosterone woant last very long in the body and will probably need to be injected every day, even multiple times a day. The major advantage of pure testosterone is that users get exactly the amount of testosterone that the vial says is there and because of testosterone suspension  pure anabolic/androgenic ratio of 1:1, it is the most potent testosterone you can put in your body by weight available
The most popular practice with Testosterone suspension is to inject the drug every day. The dosage will vary greatly depending on the needs of the individual, but is most often in the range of 50mg to 100mg per shot. In most cases the results will be amazing. Although some users will complain about discomfort when injecting water-based steroids, suspension is usually well tolerated
