As you guys know MGF is a spliced variant of IGF-1. And we know MGF is greatly increased following exercise and isn't tapered off until around day 4 in mice while IGF levels begin to rise at the same time. We know MGF inhibits myotube formation but to what extent? To further back my "don't use MGF past 24-36 hours after a workout, check out these amounts that the body naturally expresses.
Day 1
IGF-Ea: 3 picograms of IGF-1Ea per microgram of RNA
MGF: 0.40 picograms of MGF per microgram of RNA
Day 2 (
IGF-1Ea: 4 picograms of IGF-1Ea per microgram of RNA
MGF: 0.46 picograms of MGF per microgram of RNA
Day 3
IGF-1Ea: 4.5 picograms of IGF-1Ea per microgram of RNA
MGF: 0.43 picograms of MGF per microgram of RNA
Day 4
IGF-1Ea: 5 picograms of IGF-1Ea per microgram of RNA
MGF: 0.38 picograms of MGF per microgram of RNA
Day 5
IGF-1Ea: 7 picograms of IGF-1Ea per microgram of RNA
MGF: 0.35 picograms of MGF per microgram of RNA
Day 6
IGF-1Ea: 7.5 picograms of IGF-1Ea per microgram of RNA
MGF: 0.27 picograms of MGF per microgram of RNA
Day 7
IGF-1Ea: 8 picograms of IGF-1Ea per microgram of RNA
MGF: 0.09 picograms of MGF per microgram of RNA
Values for Days 1-7
IGF-1Ea pg/ug --------MGF pg/ug
3-----------------0.40 (~86% less)
4-----------------0.46 (~89% less)
4.5---------------0.43 (~91% less)
5-----------------0.38 (~93% less)
7-----------------0.35 (~95% less)
7.5---------------0.27 (~97% less)
8-----------------0.09 (~99% less)
Interesting trend here, MGF drops 2% per day with respect to IGF-1Ea.
This is a huge difference between systemic IGF-1 and MGF. Yet, think of the massive dosages we are taking in! We may be replenishing our satellite cell pool but if taken too long we could be severely limiting our gains due to decreased differentiation.
It is kind of hard to say how much it is being inhibited since no one has ever had bloodwork to determine MGF RNA trainscription per total RNA but our dosages of MGF aren't far behind our dosages of LR3 IGF-1.
