But what a coincidence we're dealing with a supplier who is so remiss as to not have mentioned/addressed this quite important aspect (Mannitol) from the outset?
I can see the above "1." and 2." has been presented/structured in such a way as to suggest that they mentionend Mannitol first, and I just "happened" to raise the point a few minutes afterwards afterwards.
This is BS.
But bigger BS still is: ("TLR actually wanted to ask which would be preferred but did not wish to have any complications/arguments ensue."). hahahaha!! Yeah, sure they did. Total Rubbish!!
I don't appreciate the attempt to try and cover their as_es.
Obviously I mentioned Mannitol first and in doing so they have realized they've put their foot in it (in terms customers impression of their credibility and competency) by not mentioning it at the outset as they should have if they were competent, remotely technically knowledgeable, and anything more than some amateurs operating out of their bedroom, who at times obviously copy and paste (verbatim) technical advice they have obtained from their supplier or another external source in reply to more technical questions raised, while letting us punters think it's their in-house knowledge base which has imparted the information.
Since they say with authority ("TLR is open to running it either way") that it can be lyophilized without Mannitol (because we are dealing with a supplier who possesses so much technical knowledge, NOT!!), then they should lyophilize just native peptide and see what happens. I dare them.
And when they do (and see the result) we can then query them on the above two bracketed statements they've made and ask them how on earth they could possibly have said such things IF they were anything more than amateurs operating from their bedroom.
Did someone who dropped out of high school at the second year author the below?:
"To make a best lyophilized powder (best drug for peptide types) it is best to add mannitol to the powder. This is standard procedure. Lyophilization is obviously quality appearance and all. It can be done without it perhaps, though it may not be as 100% 'on point'"
IF I am going to contemplate putting a research compound into my body, I at least want obtain it from a supplier who has the grammar skils of someone older than 10.
Harsh perhaps?
I think not because we're talking about other peoples health here. There is simply no room for jackass incompetence and amateurism, because one day it will lead to someone getting someone hurt.
