RESEARCH ON PRODUCT COMPOSITION - WHAT AM I BUYING?

Tested samples were applied in an amount of 15µl to a BioBasic 8 Thermo Scientific column. During the analysis using the linear gradient method in H2O and acetonitrile solutions with the addition of 0.1% trifluoroacetic acid, peaks of the sought substances appeared. Their concentrations, compared to the standard chromatogram, are presented in the tables. The measurement error margin is ± 0.5µg. Conclusion: Our products contain ingredients consistent with the declared content. Source: https://synthagenlabs.com/badania-i-patenty/

Good and Healthy Sleep

Did you know that good and healthy sleep is not only long but also of high quality? Every sleep begins with the NREM phase, which usually lasts from 80 to 100 minutes. After this time, the REM sleep phase begins, lasting about 15 minutes. In adults, this sleep cycle usually repeats four or five times throughout the night. The longer we sleep, the more the length of each sleep phase changes. Take care not only of the length but also the quality of your sleep.

Frequently asked questions

This is the first supplement in the world containing OCTAPEPTIDE synthesized using our new, patented NL-PEPTIDES™ technology, known as new peptides. The new form of the peptide, NL-SELANK™, developed by us, differs significantly from the ordinary peptide form and is much more effective than the classic version.

OCTAPEPTIDE is our patented new peptide. More specifically, it is an analog, meaning a modified or more stable form of the ordinary Selank peptide. By converting it into an analog, it becomes resistant to digestive enzymes and degrading factors. Therefore, it is suitable for use in capsules.

Most of the properties have been listed in our research and patents section.

The most important ones are:

  • Elimination of anxiety and worry
  • Improvement of cognitive abilities and functions
  • Faster learning acquisition
  • Improvement of sleep quality
No. Because peptide analogs are also resistant to high temperatures, it is best to store it at a temperature up to 20°C.
We care about the quality and safety of our products, which is why all Synthagen Pharmaceutical supplements have been tested in independent laboratories—we encourage you to visit the “Research and Patents” section: https://synthagenlabs.com/en/research-and-patents/
NL-SELANK exhibits a wide range of effects and is extremely important for maintaining overall health. It primarily improves sleep quality, has regenerative effects on the brain, supports the regeneration of the nervous system, aids in memory retention, and helps eliminate anxiety.

“In line with the principle ‘better to prevent than to cure,’ it can be used preventively on an ongoing basis.

For all kinds of ailments such as: difficulty falling asleep, concentration problems, and feelings of anxiety.”

Yes. Thanks to our patented solutions. You can find more details in the “Technology” section: https://synthagenlabs.com/en/technology/.

Peptides are safe and well-researched substances, as demonstrated by scientific studies. If any side effects occur while using the NL-SELANK dietary supplement, discontinue use and consult a doctor for further guidance.

It is recommended to follow the instructions provided on the product packaging. If there are any changes to the daily dose, it is best to consult a doctor.

Before starting supplementation, especially if you are taking any medications, it is advisable to consult a doctor.

For safety reasons, it is recommended to leave at least a 2-hour gap between taking medications (such as antibiotics) and dietary supplements.

Overdosing occurs only when exceptionally large doses are taken. Adhering to the recommended daily portions does not result in an overdose.

Our products are safe; however, we do not recommend their use by pregnant or breastfeeding women. For your safety, we always suggest consulting a doctor before starting supplementation.

The product is intended for adults only.

Our products can be combined when indicated, which is considered safe even in large quantities. However, we always recommend consulting a doctor. Combining with NL-SEMAX and NL-CORTAGEN shows a synergistic effect, leading to better therapeutic outcomes.
Although it is not essential, it is recommended to take the supplement at night to improve sleep quality.

It is recommended to take our products after meals, as this may help reduce the risk of digestive issues.

Although there are no contraindications to drinking coffee during supplementation, it is best to maintain at least a one-hour gap.

Depending on the individual case, some may notice the first effects of supplementation after just a few days. For more serious issues, which have various causes, the best results are achieved after longer, regular use, typically after a month. Remember that each body reacts differently to the supplement’s ingredients.

We recommend continuing supplementation for at least one month.

Thanks to the use of double capsules, delivering peptides orally has become possible. This is our patented technology for oral peptide delivery. As a result, after swallowing the capsule, the peptide reaches its intended destination and is absorbed.

It’s impossible to completely avoid stressful situations, but adopting healthy habits can help reduce their negative impact on our bodies. Regular, relaxing sleep and physical activity are key to maintaining a good mood and inner balance, as they support relaxation and calmness. Even a half-hour walk each day can significantly improve our well-being. In times of greater stress, it’s also worth considering adaptogens, such as ashwagandha, which increase the body’s resistance to stress and positively affect memory and concentration.

Prolonged stress can lead to digestive problems and weaken our immune system. It also negatively affects the skin, contributing to the appearance of wrinkles, acne, and hair loss. Increased cortisol levels, caused by severe stress, are also associated with weight fluctuations, as it promotes the accumulation of fat around the abdomen, commonly referred to as a “cortisol belly.” In such circumstances, we are more likely to reach for unhealthy snacks and sweets.

No, none of the ingredients in this dietary supplement cause addiction, withdrawal symptoms, or affect your well-being after discontinuation.

Yes, the NL-SELANK dietary supplement can be used together with other products containing adaptogens and melanin. This combination effectively supports the nervous system, improves sleep quality, and helps reduce daily stress.

The NL-SELANK dietary supplement does not cause drowsiness and allows you to maintain full alertness. You may notice relief from tension and overall nervousness.

The depth and quality of sleep are largely dependent on what we do during the day. Chronic stress, a heavy diet, overeating, excessive work, and a rush of thoughts in the evening can negatively impact sleep. Additionally, the lack of healthy sleep habits, such as using devices that emit blue light late at night, also reduces sleep quality. Problems with the nervous or immune systems can further contribute to sleep difficulties. If sleep issues have persisted for a long time and short-term sleep aids are not helping, it’s advisable to consult a doctor and get guidance from a specialist.

Sleep problems can also be caused by a deficiency of vitamin D, which plays a role in the secretion of melatonin that regulates the circadian rhythm, and B vitamins, which support the proper functioning of the nervous system.
