The expansion of triplet repeat sequences (TRS) associated with hereditary neurological diseases is believed from prior studies to be due to DNA replication. This report demonstrates that the expansion of (CTG.CAG)(n) in vivo also occurs by homologous recombination as shown by biochemical and...

You can compare both: HGH produces a much higher spike, but its half-life is only 2-3 hours, whereas MK-677 has a half-life of around 24 hours. Additionally, comparing 20 mg of MK-677 to 4 IU of HGH shows a significant difference in price.
So, would you prefer a smaller spike, but still a significant increase (over 60-100% for both GH and IGF-1) lasting for 24 hours, or a larger spike of 100-200% but only lasting 2-3 hours? It's up to you.
