Black series injection pain

There are two main causative groups which injection pain can be categorised:

  1. Pain due to the substance being injected
  2. Pain due to route of administration

Within these two categories there are further sub-groups for causes of injection pain, and these will be discussed in further detail.

  • Concentration of active product. This is probably the most prevalent cause of post-injection pain experienced by anabolic steroid users. This is most likely due to the demand for underground laboratories to produce more concentrated steroid preparations (high mg/ml of hormone) to reduce number and volumes of injections. One good example of this is the production of testosterone propionate by many different labs. If we look at the preparation of testosterone propionate by legitimate pharmaceutical companies, we see that the maximum concentration normally produced is 50mg/ml. Despite this, most underground labs today will produce multi-use vials of testosterone propionate that are at a minimum of 100mg/ml. Hormones that contain short esters on them (like acetate, propionate, phenylpropionate) have a much higher melting point and thus cannot be made as concentrated as those with longer esters (enanthate, decanoate, etc). Although testosterone propionate can be effectively made in standard amounts of solvents and oil to 100mg/ml without crashing out of this solution, once injected in the body, the solvents tend to leach out of the solution very quickly, being absorbed much quicker than the oil. This leaves behind oil and hormone in the muscle, and at the higher concentrations (which rely on solvents to not crash in solution) this will result in some of the hormone crashing out of solution to give crystals. These crystals cause significant muscular discomfort, and also can result in the recruitment of lymphocytes involved in inflammation thus the area around the crystals can get inflamed with a build up of blood cells. This takes time to dissipate and longer for the crystals to be absorbed into the body, which is why this type of pain and discomfort usually lasts for several days.
  • Below is a list of common anabolic steroids with the maximum threshold of concentration that can be achieved before pain is experienced, once this dosage is reached pain will be felt.
    • testosterone Propionate 100mg/ml
    • testosterone Enanthate 300mg/ml
    • nandrolone Decanoate 325mg/ml
    • nandrolone Phenylpropionate 150mg/ml
    • trenbolone acetate 100mg/ml
    • Boldenone Undecylenate (eq) 900mg/ml
    • Methenolone Enanthate 75mg/ml
    • Drostanolone Propionate 150mg/ml
  • There are various different causatives of IM pain post-injection, however the most prevalent is likely to be the concentration of hormone used in the preparation and secondly to a lesser extent, the concentration of solvents used. However as outlined, with any injection this is an invasive procedure with regards to breaking the body’s natural barriers, there is always a risk of soreness and discomfort.
  • Often when injecting a substance, the physical location, that is where the needle releases the substance, can result in discomfort after the injection. This is most likely due to the substance (especially if oil based and slowly absorbed) sitting in between muscle groups or in a small muscle, as this will cause more pain than being injected into the middle of a muscle or a larger muscle. This can happen from time to time even with experienced users.

WARNING: Due to high concentrated testosterones we strongly recommend to only inject 0.5ml at first to check your individual reaction. Side effects can include post injection pain, high body temperature, flue like symptoms, lumps and other similar effects. All reactions are normal and are associated with high milligram per milliliter products.

Test Combo 500 is an oil-based testosterone blend. Test Combo 500 is an injectable steroid with Five testosterone esters – propionate (100mg) phenylpropionate (100mg), isocaproate (100mg), decanoate (100mg) and cypionate (100mg). Esters create a depot on the site of administration, and from within the muscles the hormone is released in sustained manner. The role of esters is basically to make the synthetic hormones to resist immediate metabolism. Because of esters, the hormones are released steadily to prevent fluctuation in blood levels.

The rate at which the hormones are released depends on the weight and length of the esters; some may take days, while some may take weeks. The longer and the heavier the ester attached, the longer the active life of the steroid. In the case of Test Combo 500, the propionate and the phenylpropionate esters have relatively shorter active lives.

Propionate has only one to two days of active life while phenylpropionate has four to five days. Because of these two esters Test Combo 500 provides you immediate kick, so to speak. Isocaproate, cypionate and decanoate, meanwhile, are longer-acting esters; these three ensure that the Test Combo 500 continues to exert tissue building active for a long time, oftentimes lasting for a month. Cypionate has a halve life and 12 days, Isocaproate and decanoate has active life of two and three weeks, respectively.

These characteristics guarantee that you’re going to get immediate and sustained anabolic activity from Test Combo 500.
