is hgh as delicate as people say?

hi can anyone tell me for sure that if you do not inject your sterile water into your hgh vial onto the glass and not onto the powder that it will destroy the hgh or indeed if you shake it rather than swirl it , will this also render the substance useless?, maybe this is why i feel my second lot of hgh didnt work i think i might have been a little more violent towards it, oops?

The peptide is very FRAGILE, after reconstituting slowly. slirw the vial.... NEVER shake. If shaken vigorously... is riuned.
