compounding pharmacies under direct prescription from board-certified providers
However, there are uncertainties about the long-term efficacy of the drug and what happens when people stop taking it
Repeated the above amino acids coupling and Fmoc deprotection steps with remaining amino acids as per the amino acid sequence of Semaglutide by using Fmoc-Gly- OH, Fmoc-Arg(pbf)-OH, Fmoc-Val-OH, Fmoc-Leu-OH, Fmoc-Trp(Boc)-OH, Fmoc-Ala- OH, Fmoc-Ile-OH, Fmoc-Phe-OH, Fmoc-Glu(OtBu)-OH, Fmoc-Lys(Boc)-OH, Fmoc-Ala- OH, Fmoc-Ala-OH, Fmoc-Gln(Trt)-OH, Fmoc-Gly-OH, Fmoc-Glu(OtBu)-OH, Fmoc-Leu- OH, Fmoc-Tyr(tBu)-OH, Fmoc-Ser(tBu)-OH, Fmoc-Ser(tBu)-OH, Fmoc-Val-OH, Fmoc- Asp(OtBu)-OH, Fmoc-Ser(tBu)-OH, Fmoc-Thr(tBu)-OH, Fmoc-Phe-OH, Fmoc-Thr(tBu)- OH, Fmoc-Gly-OH, Fmoc-Glu(OtBu)-OH coupled to H-Arg(Pbf)-Gly-CTC resin by linear approach to get the title compound
