What exactly is folisstatin 344, and does it genuinely function to promote muscle growth?

Follistatin is an unusual protein that inhibits the activity of another protein called myostatin, which enables it to increase muscle growth beyond what is ordinarily achievable. When follistatin was initially detected, researchers were examining the follicular fluid that was found in the ovaries of pigs. This was the first time that follistatin had been discovered. [1]

Follistatin is a naturally occurring protein that can be found in the skeletal muscle of virtually all adult or advanced mammalian species. These species include, but are not limited to, humans, rats, and cows. Follistatin may also be found in the brains of certain mammalian species. Cystine is an amino acid that is present in quite high concentrations in folistatin. Cystine is not an essential amino acid, hence its presence in folistatin is not particularly significant. On the other hand, in contrast to the vast majority of proteins that are investigated in the field of fitness, follistatin also has carbohydrates attached to it. [2]

Folistatin, or more specifically Follistatin 344 (FS344), is becoming more well-known in the bodybuilding community as a potential supplement that may rapidly increase the amount of lean tissue mass. This is due to the fact that FS344 was developed by the same company that developed Follistatin. In terms of its capacity to grow muscle, another protein known as follistatin-related gene (FLRG) acts on the same types of pathways that FS344 does. FLRG functions on the same kinds of pathways as FS344.

The relationship between Follistatin and the Growth of Muscle

Follistatin has its effect by covalently linking to and inhibiting the activity of transforming rating (TGF) peptides, such as myostatin, which is in charge of regulating and limiting the growth of muscle tissue. Follistatin Vial Follistatin is able to accomplish its goals by inhibiting the progression of muscle tissue through the transformation of growth factors. [3] Myostatin may have a regulatory role in skeletal muscle fibrosis; nevertheless, an excess of this protein may impair tissue function and lead to chronic sickness in key organs, tissues, and bone marrow. Due to the fact that this option is pertinent to the conversation, it is essential to bring it up. [4] [5]

In addition to inhibiting the degenerative effects of myostatin, follistatin inhibits the pituitary gland’s production of follicle-stimulating hormone and the hormone’s release into the bloodstream. This is accomplished by follistatin’s ability to inhibit the release of follicle-stimulating hormone into the bloodstream (FSH). [1] High levels of FSH in males may be an indication that their testicles are not functioning properly; this condition inhibits the natural development of muscular tissue, as well as recuperation and the production of hormones. [2] High levels of FSH in females may be an indication that their ovaries are not functioning properly. [6] On the other side, having an FSH level that is too low might potentially have a significant impact, not only on a person’s health, but also on their ability to reproduce.

In contrast to the demand for daily therapy that is put on certain myostatin inhibitors, such as Trichostatin A, researchers detected increased levels of FS344 up to 15 months after the initial injection (TSA). [7] [3] Follistatin is an interesting alternative therapy option for myostatin suppression since it does not require administration on a regular basis. This makes it a good candidate for the treatment.

The search for an alternative treatment for muscular problems is the fundamental impetus for the current uptick in interest displayed by the scientific community in follistatin as well as other myostatin inhibitors. This attention has only increased in recent times. Androgen steroids, which are the most often used therapy option accessible today, are linked to a range of unfavourable effects as well as significant risks to the patient’s health in the long term. You might be wondering at this point why the use of follistatin isn’t more commonplace in the field of bodybuilding and other kinds of athletics.

Does Folistatin Play a Role in the Development of Muscle?

In a nutshell, follistatin has the ability to develop muscle, but it is unknown whether or not it does so in humans. According to the findings of a number of research, the effects of follistatin on mice have been proved to be both anti-degenerative and beneficial to the growth of muscle. There are several amateur follistatin logs on gym and fitness communities, which can be found by conducting a simple search on Google; nevertheless, there is no credible research that investigates the usage of follistatin in human persons.

The mice that were bred by scientists to produce no myostatin and excess follistatin resulted in animals that had muscle fibres that were 117 percent bigger and 73 percent more total muscle fibres than the mice that were used as a control group. The mice that were used as a control group were used as a comparison to the mice that were bred by scientists to produce no myostatin and excess follistatin. [8] In addition to its capacity to inhibit myostatin, the findings of this study demonstrate that follistatin also exerts a positive impact on the growth of muscles in a number of other ways, in addition to its ability to do so. Mice in which the levels of myostatin and follistatin were both lowered had twice the amount of muscle mass as the control group, but mice in which both levels of myostatin and follistatin were lowered had four times the amount of muscle mass as the control group. [7]

When FS344 is supplied by a tiny virus, there are no substantial adverse effects on any organs, breeding capacities, serum estradiol (also known as the principal female sex hormone), luteal phase (LH), or FSH levels (also known as an adeno-associated virus or AAV). This therapy can enhance the amount of muscle mass in rodents as little as mice and as large as chimpanzees.

[1] [3] Researchers found that administering follistatin to mice with muscular dystrophy resulted in increased muscle mass, better motor function, and a lifespan that was thirty percent longer than that of animals in the control group. [2]

There is a significant association between a lack of the follistatin protein at birth and lower muscle mass. Not only is there a correlation between greater follistatin levels and increased muscle mass, but there is also a definite correlation between higher follistatin levels and increased muscle mass. [7] When a person is born with a low muscle mass, it can have a negative impact on the growth of bones, organs, and other tissues, as well as the hormones’ ability to do their jobs correctly.
A Bodybuilder’s Use of the Supplement Follistatin

The Threats Posed by the Consumption of Follistatin in Human Grade

It is possible to spend more than $4,500 on a single milligramme of human-grade follistatin, which is a very high price tag. [9] Even on the websites that sell follistatin in large quantities, there is a clear warning that it must never be administered to living beings and must be reserved only for scientific investigation. However, this does not prevent bodybuilders from experimenting with this chemical. Amateur diaries that can be seen online often dose FS344 at one injection of one hundred micrograms (mcg) each day for a period of time ranging from ten to thirty days.

Even though some users tested dosages that were higher than 200 mcg, this did not lead the effects to become any more pronounced. In point of fact, the overwhelming majority of customers said that the product had absolutely no impact at all. However, if you analyse their logs, it appears that FS344 increased their hunger; some users increased the number of calories they consumed from 4,000 to more than 6,000. A small number of users reported that injections of FS344 had amazing benefits on mass gain; however, this was only true for a small number of users.

You will experience weight gain if you dramatically increase the quantity of calories you consume over and beyond what your body needs on a daily basis. This will cause you to consume more calories than your body requires. Users who were logging FS344 at the same time that they were going through a fat loss phase found that it did not help optimise fat loss or keep muscle mass any more effectively than they would have been able to accomplish so without using FS344. It is also crucial to note out that all of these FS344 logs were on anti-androgenic steroids (AAS), and virtually all of the users were also taking a wide variety of other pro-hormones and AAS in conjunction with FS344. This was all done in conjunction with FS344.

In conclusion, follistatin is a protein that possesses the potential to play a substantial role in slowing the breakdown of muscle tissue and boosting the formation of new muscle mass. This effect might be achieved via follistatin’s ability to promote the growth of new muscle mass. It is not advised for the typical athlete or even the most experienced athletes because of its hefty price tag and the limited amount of research that has been undertaken on human subjects.
