La testosterone is a hormone androgenic which plays a key role in the bodyAlthough it occurs primarily in the testicles of men, It is also present to a lesser extent in the ovaries of women and the adrenal glands. Beyond its role in the development of male sexual characteristics, this hormone regulates essential functions such as muscle development, bone density, the sperm production and the sexual desire.
Over time, testosterone levels often decline, directly impacting health and quality of life. To counteract this negative decline, medicine has developed various alternatives ranging from injections to gels or testosterone in pillsIn this article, we'll explore the different types of testosterone available and the potential risks and benefits of using them.

Types of Testosterone
In this section, we will look at the different types of testosterone available, their uses and possible side effects.
Testosterone enanthate
El testosterone enanthate It is a type of synthetic testosterone that is administered by intramuscular injection and has a long-lasting action in the body. It is a testosterone ester that is slowly released into the bloodstream after injection, meaning the effects can last for several weeks. It is commonly used as a treatment for testosterone deficiency in men and helps improve muscle and bone mass, libido and sexual function, as well as mood and sleep quality.
Testosterone Cypionate
El testosterone cypionate is another time-released testosterone ester variant that is administered via intramuscular injection. Like Testosterone Enanthate, this variant is also slowly released into the bloodstream after injection, resulting in long-lasting effects that can persist for several weeks. This type of synthetic testosterone is frequently used to treat testosterone deficiency in men, as it can contribute to improved muscle and bone mass, libido and sexual function, as well as mood and sleep quality.
Testosterone Propionate
El testosterone propionate It is distinguished from enanthate and cypionate by its shorter duration of action in the body. It is administered more frequently than the other two and is also injected intramuscularly. Because of its short duration of action, more frequent injections may be necessary to maintain stable levels in the body. This type of synthetic testosterone is also used to treat testosterone deficiency in men and can improve muscle and bone mass, libido, sexual function, as well as mood and sleep quality.
Testosterone undecanoate
El testosterone undecanoate It is long-acting and is administered orally, unlike the other types that are administered by intramuscular injection. This type of synthetic testosterone is also used to treat testosterone deficiency in men, which can improve muscle and bone mass, libido, sexual function, mood, and sleep quality. However, it is important to note that the bioavailability of oral testosterone is lower than that of intramuscular injection, which may require higher doses of testosterone undecanoate to achieve the same effects.
Sustatanon
It is a testosterone variant Composed of four different esters of testosterone: propionate, phenylpropionate, isocaproate, and decanoate. This combination of esters is administered intramuscularly and has a prolonged action in the body. It is commonly used to treat low testosterone levels in men, as well as for therapeutic purposes in cases of hypogonadism and in some cases of erectile dysfunctionAnother option for treating male hormone levels is testosterone replacement therapy.
testosterone gel
El testosterone gel is a topical form of synthetic testosterone that is applied to the skin and absorbed through it. It is commonly used in the treatment of low testosterone levels in men and women, as well as in some cases of diabetes and erectile dysfunctionTestosterone gel is applied daily to specific areas of the body, such as the shoulders, arms or abdomen, and allows for a controlled release of testosterone into the body.

What is the difference between propionate and cypionate?
Propionate and Cypionate are two different esters of testosterone that are commonly used in Testosterone Replacement Therapy (TRT) and in the field of bodybuilding (you may be interested in reading: natural bodybuilding o vegan bodybuilding). Although both have the same base hormone, their characteristics and effects may vary due to differences in their chemical structures. Here are the main differences between testosterone propionate and cypionate:
1. Chemical Structure and Half-Life
Testosterone Propionate:
- StructureTestosterone propionate has a shorter ester in its chemical structure.
- Half-life: Approximately 2-3 days.
- Frequency of Administration: Because of its short half-life, injections are needed more frequently, typically every other day.
Testosterone Cypionate:
- StructureTestosterone cypionate has a longer ester.
- Half-life: Approximately 8 days.
- Frequency of Administration: The longer half-life allows for less frequent injections, usually once a week or every other week.
2. Start of Action
Testosterone Propionate:
- Quick start: Due to its short ester, propionate enters the system quickly and testosterone levels rise rapidly after injection.
- Effect: It is preferred by those looking for a rapid increase in testosterone and is common in short cycles.
Testosterone Cypionate:
- Slower Start: Cypionate releases testosterone more slowly into the body.
- Effect: It is commonly used in longer cycles due to its more sustained and prolonged release.
3. Side Effects Profile
Testosterone Propionate:
- Side effects: Rapid spikes in testosterone can result in more noticeable hormonal fluctuations, which could increase the incidence of side effects such as acne, water retention, and mood disturbances.
- Pain at the injection site: Some users report that Testosterone Propionate may cause more pain or irritation at the injection site due to its short ester.
Testosterone Cypionate:
- Side effects: More stable and sustained testosterone levels can result in fewer fluctuations and potentially fewer side effects related to hormonal spikes.
- Comfort: Less frequent injections may be more convenient and cause less discomfort in the long term.
4. Common Uses
Testosterone Propionate:
- Bodybuilding Cycles: Often used in short cycles and cutting phases due to its fast action and ability to better control water and fat levels.
- Testosterone Replacement Therapy: Less commonly used in TRT due to the frequency of injections required.
Testosterone Cypionate:
- Testosterone Replacement Therapy: Commonly used in TRT due to the convenience of fewer injections.
- Bodybuilding Cycles: It is also used in bulking cycles due to its sustained and prolonged release.
5. Cost and Availability
Testosterone Propionate:
- Cost: It may be more expensive due to the need for more frequent injections.
- Availability: It may be less commonly available in some regions compared to cypionate.
Testosterone Cypionate:
- Cost: It is often more cost effective due to the lower frequency of injections.
- Availability: Generally more available and common on the TRT market.
Which is better? Summary
Testosterone Propionate:
- Short half-life (2-3 days).
- Frequent injections (every other day).
- Quick onset of action.
- Possible more noticeable hormonal fluctuations and side effects.
- Commonly used in short cycles and cutting phases.
Testosterone Cypionate:
- Long half-life (8 days).
- Less frequent injections (once a week or every two weeks).
- Slower onset of action.
- More stable testosterone levels and less hormonal fluctuations.
- Commonly used in testosterone replacement therapy and bulking cycles.
The choice between testosterone propionate and cypionate will depend on your goals, personal preferences, and your doctor's recommendation. It is always important to consult with a healthcare professional before starting any testosterone treatment.

I have been prescribed TAMOXIFEN for testosterone deficiency. Now my testosterone levels have increased with this drug and it has caused my testicles to produce more of it.
What is more advisable? To increase testosterone levels in this way (by increasing the hormone endogenously with this drug), or to be administered testosterone directly in an exogenous, synthetic form?
What is your opinion on this drug Tamoxifen to treat low testosterone?
