2. Product Introduction

P21 is a cell cycle inhibitor that is involved in essential cellular processes such as cell cycle arrest, apoptosis, and transcriptional regulation, as well as differentiation, senescence, and DNA repair. Because of its role in these processes, a large body of research has studied its role in cancer initiation, progression, and response to therapy.

Currently, the evidence shows p21 to be related to tumor-suppressing activities as well as, paradoxically, tumor-promoting activities. More research is needed to understand p21's role in cancer, which may lead to the development of new therapeutic techniques.

3. P21 benefits

• Memory improvement;
• Increase in cognitive processes;
• Increase in verbal fluency;
• Improves mental health and mood;
• Increases levels of brain-derived neurotrophic factor (BDNF), an important brain-growth compound.

4. P21 Side Effects

While scientists consider P21 as a safe compound, there are two potential side effects to watch out for,  as research on animals has shown, including:

• Tiredness - most neurogenetic compounds product such effects, so this isn't something to be concerned about.
• Cognitive rebound - this side effect is rare, but it can happen.

Momentarily, there is inadequate research to legalize P21 as an over-the-counter medicine, which is why it is only available to researchers for the sole purpose of research.

In mice with AD, P21 doesn't appear to have any side effects. That doesn't mean the nootropic has no side effects, but it does suggest that it has limited side effects in the case that it reaches clinical trials. So far, the only side effects of P21 peptide noted is lower anxiety levels - which is actually rather a positive effect.

5. P21 vs Cerebrolysin

While p21 is often referred to as a derivative of cerebrolysin, they are not the same compound. Whereas p21 peptide is a synthetic analogue of CNTF, cerebrolysin is a peptide mixture with CNTF being only one of its components. P21 is comprised of only four amino acids from CNTF and is shown to be more efficacious than cerebrolysin, as per animal studies.

In recent years, scientists have abandoned cerebrolysin treatment due to it stimulating the production of antibodies against CNTF and gradually becoming completely ineffective. In fact, it can even make things worse.

At one time, this product was one of the best options one could buy. As a complex blend of different brain chemicals, it was initially an effective treatment. However, it produces high levels of foreign CNTF that causes the production of auto-antibodies, leading to adverse effects.

P21 is proven to confiscate these auto-antibodies and help to diminish them, resulting in enhanced efficacy of native CNTF. Studies show it has not shown to lose efficacy over time, either, which is a very good sign.

All in all, when it comes to the cerebrolysin vs P21 debate, the latter is the clear winner.
