Quality Assurance: Laboratory tests and analysis

Types of testosterone

Testosterone levels of human body vary throughout the day. In men, testosterone levels are higher in the morning, but decrease gradually throughout the day. The normal production of testosterone is largely controlled by the rhythmic explosions of another hormone that is released at a frequency of 1 to 3 hours. That hormone is called the gonadotropin-releasing hormone (GnRH).

To increase this natural production, there are 4 types of injectable testosterone. It is important to know which is the one that suits your needs. Below, you will find a summary to help you better understand the different mechanisms of action in the human body:

  1. Enanthate is a metabolised testosterone ester in four or five days. In some cases, low levels can remain in the body for up to two weeks. To maintain the levels, injections must be administered every five days. This form of testosterone is usually given by intramuscular injection (IM) at the initial dose of approximately 100 to 200mg every five to seven days.
  2. Cypionate is considered a “long-acting” testosterone that is metabolised in approximately seven to eight days. Cypionate often starts with an initial dose similar to that of enanthate (100 to 200mg) but is administered only every seven days.
  3. Propionate is a fast-acting ester. This testosterone ester can reach its maximum in the blood a few hours after its administration and get metabolised for three days. Injections should be administered every two or three days. You must weigh the “positive” with the “negative” before using propionate. It is only prescribed in special cases, because it must be frequently administered.
  4. The aqueous suspension of testosterone is also known as “no ester”. This form of testosterone requires frequent intramuscular injections as it remains in the body for a reduced and limited number of hours. The injection is usually very painful, and experience has shown that risks outweigh benefits. This particular form is not recommended.

Advantages of testosterone

In adults, testosterone has positive effects throughout the body:

  • Muscles: increases protein synthesis and increases muscle mass and strength.
  • Body fat: blocks the absorption of fats and their storage and increases the number of fat burners of beta-adrenergic receptors.
  • Brain: improves cognition, memory, libido and affects feelings.
  • Heart: increases blood flow and cardiac output.
  • Bones: increases the production of red blood cells and bone growth and maintains bone density.
  • Male sexual organs: promotes the production and viability of sperm, promotes the growth of the penis and erectile function.
  • Skin: promotes the production of collagen and produces hair.
  • Kidneys: produces erythropoietin (EPO), which stimulates the production of red blood cells.

Also, testosterone increases the insulin-like growth factor (IGF-1) and healthy levels of testosterone are associated with good health and immune function, with lower mortality rates, with a decrease in body fat and with an increase in the metabolic rate.

It has also been proven that supplementation with hormones improves energy, muscle mass, libido, sexual performance and bone mineral density in men with low levels of testosterone, as well as generates a reduction in body fat.

Checking the quality of testosterone is important

It is essential to trust your supplier of anabolic products. Once the risks and limitations of the environment are known, it is everyone’s responsibility to know how to buy and acquire quality products through recognised online stores or through their personal network. The reputation of the laboratory must be checked, as well. Below, you will find some elements to better understand the manufacturing process:

  1. Each ml of the oils must contain the exact amount of raw material. This is to avoid insufficient dosing. Production level, the filling parameters of production lines must be checked before starting to produce each new batch.
    Ideally, always add a little more oil in each bottle to consider the small amount of oil that will remain on the needle after injection.
  2. Sterilisation of oils for intramuscular injections is mandatory to be 100% sure of not catching staphylococci or other bacteria. Pharmaceutical grade ethyl oleate additives can also be added to the formula so that injections are not painful.
  3. Laboratory tests  on raw materials and finished products should be provided by the laboratory. The brand can also provide tests from other external laboratories. Users can even review the products by themselves if they so wish. 
  4. Elements of protection against counterfeiting are important, including verification codes, which can be verified on the site of the brand. You can tell if your product is authentic or not.

Testosterone can sometimes come from clandestine laboratories. Needless to say, it is preferable to play Russian roulette than consuming these types of products.

In 2019, the offer in the market makes it possible to no longer buy products from these pseudo-laboratories, since legal brands produce them and sell them at very good prices.

Therefore, it is essential to purchase your product from reputable sources whose suppliers are well-known laboratories with an unblemished reputation.

“Nowadays, pharmaceutical testosterone can be bought at a price of 24.90 euros up, so it would be crazy to buy underground products. ” Arnaud Sylvain.

Here are some details of the manufacture process:

  1. Each pill must contain the correct amount of raw material. Be careful with the sub-dosed products. Only a fully automated production line makes possible getting the correct dosing. In fact, only a legal laboratory can confirm this information.
  2. Laboratory tests on raw materials and finished products should be provided by the laboratory. Brands can also provide tests from other external laboratories. Users can even review the products by themselves if they so wish. An independent site like anaboliclab.com is a reference. 
  3. Elements of protection against counterfeiting are important, including verification codes, which can be verified on the site of the brand. You can tell if your product is authentic or not.
