NovaStemix® Supplementary User Observations - Three Anonymised Cases and Everyday Experiences

Sleep, energy, bowel habits and how people feel during everyday activities are all matters that users care about. Some changes can be recorded through questionnaires, while others emerge from chats, telephone conversations and longer-term individual follow-up.

In our previously published article, “NovaStemix® Six-Week User Observation: Results from 20 Participants”, we presented paired questionnaires completed before and after use by 20 NovaStemix® (NS) users. This article introduces three anonymised cases and brings together feedback on topics not specifically covered by the questionnaires, including bowel habits, men’s health experiences and seasonal respiratory symptoms. These records vary in source and completeness. We aim to present both the changes users reported and the limits of what the available records can establish.

To protect privacy, we refer to the individuals as Mr X, Mr Y and Mr Z. Mr X and Mr Y were already included in the original group of 20. Their case histories provide supplementary information and do not increase the sample size in the original report.

Mr X: Sleep, Bowel Habits and Longer-Term Examination Records

Mr X reported that, while using NS, his sleep difficulties eased, his energy improved and bowel movements became easier. In addition to describing his experiences, he provided reports from three echocardiographic examinations. These examinations took place between January and September 2026, spanning approximately eight months. His documented cumulative use of NS was about six months, so the examination period and the actual period of use did not fully coincide. Across the three examinations, some measurements of left-sided cardiac chamber dimensions decreased, and the hospital’s written assessment of left ventricular diastolic function also changed. Meanwhile, ejection fraction remained around 62% to 63%, and moderate aortic regurgitation persisted.

These findings need to be interpreted in the context of his full clinical course. Mr X was receiving standard medical treatment at the same time, and his prescription medications were adjusted. It is therefore not currently possible to isolate any independent contribution of NS to the changes seen on examination. His reports concerning sleep and bowel habits have also not been assessed using dedicated scales or continuous diaries.

Mr Y: Self-Reported Sleep, Breathing and Daily Activity

Mr Y reported a history of heart failure over many years and continued use of standard prescribed medication. He described previous difficulties including shortness of breath, difficulty lying flat at night, marked fatigue and limited activity. During follow-up, while using NS and continuing other treatment, he reported easier breathing, being able to fall asleep lying flat, fewer palpitations and related symptoms, and improvements in his perceived stamina and daily functioning.

These changes were meaningful in his day-to-day experience. However, the available information largely consists of his own account, and the corresponding complete echocardiography, electrocardiography, laboratory and prescription records have not yet been obtained. This article therefore describes his personal experience; it does not establish a therapeutic effect on cardiac function or heart rhythm, nor does it provide a basis for others to change their medication.

Mr Z: Personal Experiences and Two Testosterone Test Results

Mr Z was 68 years old at his health examination in March 2026. The two laboratory test reports he provided recorded testosterone concentrations of 10 nmol/L at the earlier test and 15.20 nmol/L at the later test. Both results fell within the male reference ranges used by the respective laboratories. According to his additional account, he started using NS powder around October 2025 and switched to capsules about two months later. By the time his blood sample was taken in March 2026, his total period of use was approximately five months. He also described positive changes in how he felt and believed that these changes were related to NS.

Several details remain relevant to interpretation. The tests were performed approximately nine and a half months apart at different laboratories, and the blood sampling conditions and analytical methods were not fully matched. The earlier test was also not carried out immediately before he started using NS. The formulation, dose and batch information for the powder and capsule phases still needs to be checked against his usage history. This is an individual observation that warrants continued follow-up; it does not yet demonstrate that NS increased testosterone levels.

What Else Have Users Mentioned Beyond the Questionnaires?

Changes in bowel habits. In addition to Mr X, other recorded feedback described improvements in bowel habits or more formed stools. These changes directly affect everyday comfort and are worth including in future records. However, bowel movement frequency, stool form and concurrent changes in diet, fluid intake, exercise and medication have not been recorded consistently. It is therefore not possible to identify the causes or conclude that the gut microbiota or bowel motility has changed.

Recollections of cold frequency and respiratory symptoms. In family accounts and chat records, some people recalled having fewer colds than before during the period of use, while others felt that their respiratory symptoms during a particular episode were milder than those of people around them. These experiences concern frequency and severity, respectively, and should not be combined into a single outcome. Standardised records of previous episodes, observation periods, diagnostic information and comparison groups are currently lacking. These accounts cannot therefore be used to calculate changes in infection risk or to conclude that NS prevents colds or influenza.

Men’s health experiences. Other male users mentioned changes in nocturnal or spontaneous erections, as well as subjective impressions of sexual function and their mental state. These topics were not directly measured by the six questionnaire domains used previously, and standardised follow-up has not yet been conducted. The different experiences need to be recorded separately and should not automatically be interpreted as an increase in testosterone or a clinically established improvement in sexual function.

Discomfort early in use should also be recorded. Two entries in the family-reported records described stomach discomfort and diarrhoea early in use, which subsequently eased or resolved. The available records are insufficient to determine whether these symptoms were related to NS or to estimate their frequency. Anyone experiencing persistent, worsening or concerning symptoms should seek professional advice promptly.

Making Future Feedback More Complete

These additional observations provide insight into experiences beyond the questionnaires and highlight the need for more consistent record-keeping. More informative feedback should, wherever possible, include the start date, the actual amount taken, when changes first appeared, and any concurrent treatment or lifestyle changes.

Bowel habits can be recorded in terms of frequency and stool form. Records of respiratory symptoms can include the date of onset, duration and whether medical care was sought. Laboratory measurements should, wherever possible, be repeated under comparable conditions.

Positive changes, no appreciable change and any discomfort during use should all be recorded. Consistent and complete record-keeping can help us better understand users’ experiences and formulate testable questions for future research.
