I understand stumbling across something for free and wanting to take it, but Sermorelin is a grf that is borderline useless when compaired to mod grf 1-29 also known as cjc1295.
The half life of Sermorelin is about 5 min while 1295 is around 30min.
I agree with Doc, both of them are not worth taking with out some sort of GHRP rather it be 2,6, Hex, or Ipamorelin. Ipamorelin being my choice due to deeper sleep and no raise in cortisol or prolactin.
I have found there is great upside to raising your natural GH levels (peptides) while adding a synth.
Just IMO bro, good luck with it.
