Can anyone tell me about Myostatin Inhibitors. Does anyone know of any safe performance enhancing drugs?
All the men on mother side are big guys 6 ft plus..and apparently i’ve taken after them…I can see it aswell..same physical structure, and looks..The thing is they were all skinny at one point like me..What my question is, is how much does myostatin really limit one ability to be big?..Is it to the point of absurd gains of muscle mass..I.E: 220+ pounds or can it take effect at much earlier stages..I.E: 150+…I’m just curious because i’m 6ft 128lbs…and have eaten extremely poorly my entire life..yet i’m skinny :S…I’ve always been very quick and agile and athletic..I play I wide variety of sports…Furthermore, I can hang on a 10 ft rim..I’ve never worked out b4..However, I don’t feel the need to workout if I won’t make significant gains..What do you think?Thx for your concern..lol
Can I be Be Muscular and Add Mass?
Most of the men in my family were all relatively skinny when they were young until 25 or so. At about this age, they all began putting on significant size..so my question is does myostatin which is an inhibitor lower with age?..Many men become stronger with age..How come?..Furthermore, I’ve always been extremely strong for my size and weight but not big..My cousin who weighs 15 lbs more than me cannot beat me in an arm wrestle but his arms are significantly bigger. Moreover, I am also much faster than him..does this mean I have potential to put on mass and strength..or simply that i’ve reached my genetic potential?..I’ve never worked out before but have played sports.
ThxDon’t eat well at all..super fast metabolism so i’m not fatHe not fat…He about 5′10 145 lbs
and i’m 6ft 128 lbs..
Also, my younger brother is the same weight and height as me..but i’m significantly stronger and faster than he is…I’ve always felt that we’ve gotten different genes..I’m an extremely athletic person whereas he isn’tAlso, for all you answers can you actually have something to contribute rather than joke around and waste my time..thx*answerers
Does Myostatin Lower With Age?
Is it possible to gain muscle mass so quickly that your skins and/or veins split open? With like heavy steroid use or a myostatin deficency or whatever?
Could you gain muscle mass so quickly…
I was reading an news article about a protein called myostatin and how it could be used to create drugs promoting muscle growth for people suffering from MD and other froms of atrophy. Does anyone have more information about myostatin?
Myostatin?
just read about a condition called “Myostatin-related muscle hypertrophy”. When a person has a deficiency in Myostatin production, they exhibit a ridiculous amount of strength and muscle mass, up to 40% more than a normal human being. One example is 19 month-old Liam Hoekstra, who has thigh muscles reminiscent of Lance Armstrong, and performed his first iron cross at 5 months.
What i’m wondering is if this condition makes a person super strong, would it be so far-fetched to think that historical figures such as Hercules and Sampson had this genetic mutation? Is there any historical evidence or research to support that theory?

Surely anyone with super strength in that time period would have become legendary?
Super human disease?
Ive come across a couple of Supplements on the net that claim to be Myostatin blockers, that are supposed to reduce the chemical myostatin which limits muscle growth allowing for extreme muscle growth, but Ive also read(I may be wrong) but that scientist have only tested a myostatin blocker on lab rats, and the rats that were given the blocker were far more muscular than the normal rat, but It said nothing about any supplements that had come out that bodybuilders could actually use yet. I was just thinking could these Myostatin Blocker supps be a sham or is it for real? I really dont want to waist my money on this if it doesnt actually work. Remember Im not completely sure Im just going by what I have read. TY

Myostatin Blocker Supps???
Myostatin (formerly known as growth differentiation factor 8) is a growth factor protein that limits muscle tissue growth, i.e. higher concentrations of myostatin in the body may cause the individual to have less developed muscles. The myostatin protein is produced primarily in skeletal muscle cells, circulates in the blood and lymph and acts on muscle tissue, apparently by slowing down the development of muscle stem cells. The precise mechanism remains unknown.
Myostatin has been found in humans and several other mammals, as well as in birds and fish. Its functions in non-mammalian vertebrates appear to be somewhat conserved, as muscle-specific actions have been demonstrated in birds. However, it is produced in many different fish tissues, suggesting that it may regulate more than just muscle mass in these vertebrates.
Myostatin and the associated gene were discovered in 1997 by geneticists Alexandra McPherron, Se-Jin Lee and Ravi Kambadur, who also produced a strain of mutant mice that lack the gene and permanently have approximately twice as much muscle as normal mice. These mice were subsequently named “mighty mice”. The gene has been sequenced in humans, mice, several other mammals and many different fish species, most of which are current or potential cultivars. The primary coding sequence is highly conserved among all vertebrates as is the genomic organization . These and other recent studies also indicate that the myostatin gene in fish has been duplicated as most fish species possess two distinct myostatin genes (MSTN-1 -2) while salmonids have four (MSTN-1a, -1b, -2a -2b) This further suggests that the physiological and developmental aspects of myostatin biology may be quite different from that in mammals.
Ravi Kambadur and his team found in 1997 that the double muscled cattle breeds Belgian Blue and Piedmontese have defective myostatin genes; these strains have been produced through breeding.
In 2004, a German boy was diagnosed with a mutation in both copies of the myostatin-producing gene, making him considerably stronger than his peers. His mother, a former sprinter, has a mutation in one copy of the gene.
An American boy born in 2005 was diagnosed with a clinically similar condition but with a somewhat different cause. In contrast to the first case, this boy produces a functional myostatin, however he has a defect in his myostatin receptor so that his muscles do not respond to the myostatin signal.
Myostatin is a member of the TGF beta superfamily of proteins.
Human myostatin consists of two identical subunits, each consisting of 109 amino acid residues. Its total molecular weight is 25.0 kDa. It can be produced in genetically engineered E. coli or eukaryotic cells and the recombinant protein from both sources is commercially available. However, due to the unique manner by which the mature protein is processed, there is considerable doubt as to the effectiveness of myostatin generated in E. coli.
A 2007 NIH study in PLOS Genetics found a significant relationship in whippets between a myostatin mutation and racing performance. Whippets that were heterozygous for a 2 base pair deletion in myostatin were significantly over-represented in the top racing classes. The mutation resulted in a truncated myostatin mRNA, likely resulting in an inactive form of myostatin.
Whippets with a homozygous deletion were apparently less able runners although their overall appearance was significantly more muscular. Whippets with the homozygous deletion also had an unusual body shape, with a broader head, pronounced overbite, shorter legs, and thicker tails. These whippets have also been called “bully whippets” by the breeding community due to their size, but not their temperament.
This particular mutation was not found in other muscular dog breeds such as boxers and mastiffs, nor was it found in other sighthounds such as greyhounds, Italian greyhounds, or Afghan hounds. The authors of the study suggest that myostatin mutation may not be desirable in greyhounds, the whippets’ nearest relative, because greyhound racing requires more significant endurance due to the longer races (900 meters for greyhounds vs. 300 meters for whippets).
Further research into myostatin and the myostatin gene may lead to therapies for muscular dystrophy. The idea is to introduce substances that block myostatin. In 2002, researchers at the University of Pennsylvania showed that monoclonal antibody specific to myostatin improves the condition of mice with muscular dystrophy, presumably by blocking myostatin’s action.
In 2005, Lee showed that a two-week treatment of normal mice with soluble activin type IIB receptor, a molecule that is normally attached to cells and binds to myostatin, leads to a significantly increased muscle mass (up to 60%). It is thought that binding of myostatin to the soluble activin receptor prevents it from interacting with the cell-bound receptors.
It remains unclear whether long term treatment of muscular dystrophy with myostatin inhibitors is beneficial: the depletion of muscle stem cells could worsen the disease later on.
As of 2009, no myostatin-inhibiting drugs for humans are on the market, but an antibody genetically engineered to neutralize myostatin was developed by New Jersey pharmaceutical company Wyeth. The inhibitor is called MYO-029, but after an initial clinical trial, Wyeth says they won’t be developing the drug. Some athletes, eager to get their hands on such drugs, turn to the internet, where fake “myostatin blockers” are being sold.
Johns Hopkins University has developed a technique for detecting mutations in myostatin variants.
