Here is a protocol for stress that can be helpful. This is a peptide based protocol that does involve selank and cerebrolysin.
Cerebrolyin should be loaded for one week at 10mls per day for 7 days.
Then from there you can maintain it at a dosage of 5-10mls 1-2 times per week.
The other way that you can implement this is through using 1-2mls per bed when you are feeling stressed or overwhelmed I find this helpful for promoting good sleep when it may be compromised.
I also like to deploy something like selank at a dosage of 200mcg three times per day as a nasal spray for 3-4 weeks before taking a break of two weeks.
Another thing that has helped me alot is Delta sleep inducing peptide at 300mcg pre bed.
With this stack you will notice a significant decrease in stress.
