DMSO-Dihexa ocular/eyeball delivery
Original post in this thread
dihexa · 5 points
After using Dihexa through different ROIs (IM, oral, transdermal DMSO, through the nose) and at different doses, I am a little frustrated that I haven't had any real 'success'/'breakthroughs' with it (beside a few vivid dreams), unlike others, who have posted their positive results across several forums.
I'm interested in using DMSO (75%) to dissolve what I have left of this hydrophobic peptide and then deliver it ocullarly to achieve maximum bioavailability. Besides IV (which isn't an option for me), there doesn't appear to be any decent ROIs with high enough bioavailability. I can't find much (officially) about the safety of applying DMSO to the eyeballs, which is my major concern... beside this paper excerpt from 1968:
if any single fact has emerged from animal and human studies with DMSO to date, it is that the lens toxicity findings originally reported in dogs and later confirmed in certain other species have no equivalent or counterpart in human therapy utilizing DMSO in generally accepted regimens.
My solution of DMSO-Dihexa would be about 30 drops in total. That's 50mg of Dihexa diluted in ~30 drops of 75% DMSO-saline to then be dropped into my eye/s.
What do you…

Are you talking about the speculated seizure risk when you say "reason", or is it just about the DMSO?
Also, I thought the half-life of the drug was 12 days. That would mean that you could perhaps get away with dosing only once or twice a week. Would using DMSO that irregularly reduce the risk of the smelly side effects? Also, what is neurotoxic about DMSO?

Well those reasons are there too. But that comment was referring to the feasibility of its use. It is soluble in DMSO and acetonitrile, which are not really ideal for ingestion. Since Dihexa is not orally bioavailable, and not water soluble, that makes it very hard to use safely.
Also, what is neurotoxic about DMSO?

That is dose-dependent, which is why I said that it can be neurotoxic. However, pair that with cream corn sweats, and it makes the use of DMSO in nootropic formulations something to avoid.
