MGF is a produced within the
body, as a form of IGF-1, when mechanical resistance is
applied to muscles (such as weight training). At this point, the
IGF-1
gene is spliced to produce IGF-1Ec (which is another name for MGF).
This production of MGF can stimulate satellite cells into activation,
to create new muscle fiber. MGF also promotes nitrogen retention and
new protein synthesis. It could actually be the case that this
particular expression of
MGF
(IGF-1Ec) is an important part of the deciding factors in whether a
muscle will grow or not
The introduction of this peptide, either by weight training or by an
injection, will cause the affected area to respond by producing new
muscle tissue.
It would
be safe to say that MGF presence in the muscle is one of the most major
factors in the anabolic effect of resistance training (weight
training).
MGF is highly anabolic, as regards both inducing satellite cell
activation as well as promoting protein synthesis. MGF is very likely
the most dominantly anabolic portion of the IGF-1 peptide, as
demonstrated in rodent studies, where it produced a greater increase in
muscle weight, over a shorter time as compared to IGF-1 alone. However,
when
IGF-1 and MGF are
used together, they appear to act synergistically and promote rapid fat
loss and new muscle growth. It is highly likely that using
both of them together is the best possible combination of peptides for
muscle growth and fat loss. MGF has not been shown to affect fat loss
or strength in the same way that
IGF-1
does, and IGF-1 has been shown in studies to produce less (although
still impressive) muscle growth compared to MGF.
Currently, this compound is being used successfully by bodybuilders,
for bringing up lagging body parts as well as overall growth. Results
seem to be dose dependant and as previously stated, multiplied greatly
when used concurrently with Lr3IGF-1.
