    Dihexa is something the team of rats over here do a month on and month off. We like it. It seems to adversely affect my sleep if i take it after lunch time. This would be at the top of my list.

    Pinaelon is an injectable russian bioregulator you should look into.

    Theres also PRL-8-53 which is a tablet. Ive been researching it. seems to help with the fog but could be placebo.

    Cerebrolysin is another one. If you can't find a source for that dm me and i can point you in the right direction. Theres a few members on here experimenting with their rats and this compound right now

    @Randy hey bud,

    There is 2 forms of Cerebrolysin in the market, ampules and powder.

    I have both and looking for my rat to run it this year…

    Dosing is all over the place and methods of delivery.

    Has Randy done any RS on this.

    Thanks

      I have no experience with this one. It actually scares the crap out of me. Will I grow another brain? Im staring at 4 boxes of the chinese stuff on my desk.

        Glad you guys are talking about this. Are you guys pinning or doing nasal?

          semax/selank are nasal. Dihexa is oral (dont pin it). I've tried all forms of those. thats my preference.

          Still staring at the box of Cerebrolysin pondering

                @randy - if I want to make a nasal spray of Selank that will administer 300mcg per spray, but my vials are 10mg each, I'd have to reconstitute 1ml of bac in each of the 3 vials and combine, correct? My lab rat is a big fan of Selank and has only used subq (3-4 weeks) with good results, but would like to compare the effects of delivering it through his little rat nose.

                  What is the better version to purchase... N-Acetyl Semax Amidate or just regular Semax? Thanks

                    ive sniffed both and didnt notice a difference. N-acetyl is supposed to be more stable/degrades slower.

                      @Tim-Cheese im assuming your sprayer gives out 10ish units. 3.2ml with 10mg gives 300mcg with one spray according to our fancy pants calculator https://peptidecritic.com/tools/peptide-calculator

                        @Randy I just reconstituted 10mg Selank with 1 ml bac water and 5 ml saline and the calculator calls for 15 units for a 250mcg. My understanding is 1 pump delivers 10 units so not sure how to do a 1/2 spray. Go low with 1 then to 2 is my plan or try a half? 😕

                          its 10/15 units. This isnt the most accurate method so one spray is fine. So is two. Absorption is based on technique and your rats nasal health.

                              What about Adamax? I’ve been doing a lot of research and it looks great for focus brain fog etc?

                                  I have a relative who is dealing with brain fog and other minor stroke cognitive issues. I just started him on 250mcg of Semax every day and am looking for any advice or recommendations.
                                  What other peptides are out there? I’ve seen Dihexa but don’t k ow much about it.

                                  @Bl8kStr I have been researching for a stroke (basal ganglia) research subject since last October. My subject has cognitive & speech issues, and extreme mood shifts. Most noticeable results with improvement in cognition, communication & mood so far have been from a daily regimen of VIP , PE-22-28 and Pinealon.

                                  We have also done several cycles of KLOW & SS-31 for overall healing and mitochondrial benefits.

                                      @Randy We started with PE-22-28 at 250 mcg subQ once a day for a week then increased to 500mcg once a day (mornings). Cycle 6 weeks on - 1 week off.

                                        I was reading in the Cerebro-something or other thread about hair loss associated with Semax use. That is the first time I have ever heard about that side effect. So I went down a rabbit hole and all I see is a lot of reddit anecdotes indicating that you’re an idiot if you don’t know Semax makes your hair fall out, and one article indicating that none of the human research done on Semax reports hair loss as a side effect. There was one study indicating BDNF may increase hair loss for those predisposed to hair loss.

                                        Is this a thing?

                                        Also, am looking for Dihexa. It seems to have limited availability from vendors on this site. Is there a preferred source? I have been on the Nexaph wait list for a while.
