Research subject over 50, male. Has used nasal Semax and Selank separately for roughly two months, beginning early December with the amidated versions. First week used 250 mcg sprays of each once daily in the morning to check tolerance, with none noted and only slight calmness or focus that might have been placebo. Weeks two through four doubled to 500 mcg daily with still no clear benefits or issues. Weeks five through eight switched to regular versions after running out, raising Semax to 800 mcg split twice daily while keeping Selank at 400-500 mcg but moving it to evening. Effects stayed minor and inconsistent. Now taking a break to reset. Overall no strong improvements observed and unsure about continuing long term.
Gathering lab rat preclinical notes on these two peptides and hoping for contributions from those who've tested them. Key areas: comparing injection under skin to nasal delivery, using one or both together, impacts on behavior, thinking, anxiety, and brain signals. Also practical stuff like amounts, how often, when, breaks, and if the way it's given affects how reliable the results are. Any irritation or other signals. If you've done rat studies, share strain details if possible, dosing amounts and schedule, how given and prepared, if both at once or separate times. Not seeking health guidance, just method info to compare experiences. Right now my subject is three days into under-skin Selank starting around 330 micrograms from a certain vial mix and aiming up to 500.
