The present invention relates to polypeptide compound optimized for subcutaneous administration, exemplified by growth hormone conjugates having a linker providing non-covalent binding to albumin. 1. A growth hormone conjugate which comprises a growth hormone compound (GH) linked to an albumin binding residue via a hydrophilic spacer , or a pharmaceutically acceptable salt , solvate or prodrug thereof.2. The conjugate of wherein the growth hormone conjugate has the formula (I):{'br': None, 'A-W-B-GH\u2003\u2003(I)'}wherein:GH is a growth hormone compound,B is a hydrophilic spacer,W is a chemical group linking A and B, andA is an albumin binding residue.3. The conjugate of claim 1 , wherein GH is hGH (SEQ ID NO:1).4. The conjugate of wherein B has the formula{'br': None, 'sub': 1', '2', '3', '4, '-X-X-X-X-'}wherein{'sub': 1', '1', 'l1', '2', 'm1', '2', 'n1', 'm2', 'l2', '3', 'm3', 'n2, 'sup': 1', '2, 'Xis —W—[(CHR)—W]—{[(CH)E1]—[(CHR)—W]}—;'}{'sub': 2', 'l3', '4', 'm4', '2', 'n3', 'm5', 'l4', '5', 'm6', 'n4, 'sup': 3', '4, 'Xis —[(CHR)—W]—{[(CH)E2]—[(CHR)—W]}—;'}{'sub': 3', 'l5', '6', 'm7, 'sup': '5', 'Xis —[(CHR)—W]—;'}{'sub': 4', '2', 'l6, 'Xis F-D1-(CH)-D2-;'}l1, l2, l3, l4, l5 and l6 independently are selected from 0-16;m1, m3, m4, m6 and m7 independently are selected from 0-10;m2 and m5 independently are selected from 0-25;n1, n2, n3 and n4 independently are selected from 0-16;{'sub': 2', '2', '1-6, 'F is aryl, hetaryl, pyrrolidine-2,5-dione or a valence bond, wherein the aryl and hetaryl groups are optionally substituted with halogen, —CN, —OH, —C(O)OH, —C(O)NH, —S(O)OH or C-alkyl;'}{'sup': 1', '2', '3', '4', '5, 'sub': 2', '2', '2', '1-6, 'R, R, R, Rand Rindependently are selected from hydrogen, —C(O)OH, —C(O)NH, —S(O)OH, —S(O)OH, —NH—C(═NH)—NH, C-alkyl, aryl or hetaryl;'}wherein{'sub': 2', '2, 'the alkyl, aryl and hetaryl groups optionally are substituted with halogen, —C(O)OH, —C(O)NH, —S(O)OH, —S(O)OH, —CN or —OH;'}{'sup': 6', '7', '6', '7, 'sub': 1-6', '1 ...
