IGF is a research drug, it hasn't been approved by
the FDA for use as a pharmaceutical and it is currently
being researched for nerve tissue repair, possible
burn victims, and also as a possible aid in muscle
wasting for AIDS patients.
IGF-1
Variations
There are many different analogs of IGF available,
instead of mentioning them all, I will simply mention
the two most common and the most effective. Regular
recombinant IGF is one of the two, it is also the
more expensive and the least effective. Regular IGF
only has a half-life of about 10-20 minutes in the
human body and is quickly destroyed, it can be combined
with certain binding proteins to extend the half-life,
but it is not a very simple procedure and there is
a more effective and less expensive version available.
About IGF-1 Long R3
The most effective form of IGF is Long R3 IGF-1, it
has been chemically altered and has had amino acid
changes which cause it to avoid binding to proteins
in the human body and allow it to have a much longer
half life, around 20-30 hours. "Long R3 IGF-1
is an 83 amino acid analog of IGF-1 comprising the
complete human IGF-1 sequence with the substition
of an Arg® for the Glu(E) at position three, hence
R3, and a 13 amino acid extension peptide at the N
terminus. This analog of IGF-1 has been produced with
the purpose of increasing the biological activity
of the IGF peptide. It is also not as expensive since
a media grade version is available which is sufficient
for bodybuilding use.
Differences
between IGF-1 and HGH (human growth hormone)
There is a lot of talk about the similarity between
IGF and growth hormone. The most often asked question
is simply which is more effective. GH doesn't directly
cause your muscles to grow, it works very indirectly
by increasing protein synthesis capabilities, increasing
the amount of insulin a person can use effectively,
and increasing the amount of anabolic steroids a person
can use effectively. GH also indirectly causes muscle
growth by stimulating the release of IGF when it (the
GH) is destroyed in the human body. So one way you
could look at it as GH being a precursor to IGF. So
to put it simple IGF is more effective at directly
causing muscle growth and density increases. IGF is
also much more cost effective. IGF can also be effectively
used by itself and gains will still be easily noticeable.
With growth hormone you need to use high amounts of
anabolics and often insulin to see any gains at all,
this is not the case with IGF.
