Key takeaway
Over 11 months (August 2025 — July 2026), 163 DOZA clients reported numeric weight-loss results: −1,026 kg in total, a median of −4.0 kg per client, and one in four losing over 10 kg. First-month median: −4.8 kg. Side effects, when present, lasted 1–4 days. Data was collected from support conversations, anonymized, with full methodology and limitations.

From base to every metric
Different report blocks rely on different denominators. Here is how the sample narrows from all clients to those who reported specific data.

the “1–4 days” figure
Dialogues in the support archive: 1272; Clients with a confirmed order: 908; Reported a numeric weight result: 163; Sent body measurements (cm): 35; Specified side-effect duration: 16
Each block of the report relies on its own denominator. For example, “1–4 days” is n=16, not all 163 clients; the % of body weight is n=33. So the headline figures and the narrower metrics should not be conflated.
How much weight do DOZA clients lose?
Result distribution: weight loss range (kg) and number of clients in each range. For many clients the result is interim — their program continues.
0,5–2 кг: 17 clients; 2–4 кг: 48 clients; 4–6 кг: 29 clients; 6–8 кг: 17 clients; 8–10 кг: 11 clients; 10–15 кг: 26 clients; 15–26 кг: 15 clients

Side effect duration (n=16)
Percentages are of the 163 dialogues with results: 58% explicitly reported feeling well, 33% mentioned at least one adverse symptom, and the remaining ~9% did not give a clear wellbeing assessment. Side effects were mostly mild nausea, less often stomach heaviness and fatigue. Only 16 clients specified duration — all reported 1–4 days after the injection, after which symptoms resolved; there is no case lasting over a week in the conversations. The manager tracked wellbeing weekly.
Result as % of starting weight
n=33 · starting weight known−5,1%
Median of body weight
−8,1%
Mean of body weight
33%
lost ≥10% of body weight
For 33 clients whose starting weight is known from the conversation, the median result is 5.1% of body weight (mean 8.1%, range 1.1–31.2%). A percentage is more meaningful than absolute kilograms: −5 kg for a 65 kg vs a 140 kg person are very different results. Figures are self-reported and interim: for many clients the program is still ongoing.
Weight loss pace
109 cases where the observation period is known from the conversation. The picture matches clinical GLP-1 program data: a fast start in the first month (−4…−6 kg), then a steady pace of 1–2 kg per month.
| Observation period | Cases | Average loss | Median |
|---|---|---|---|
| ~1 month | 45 | −5.8 kg | −4.0 kg |
| 1.5–3 months | 31 | −6.2 kg | −5.0 kg |
| 3–6 months | 20 | −8.2 kg | −4.0 kg |
The “−4.8 kg first month” figure is the median for results reported at weeks 3–6 only (n=38). The “~1 month” row in the table uses a broader group of roughly monthly observations (n=45), so the samples and medians differ. Results are cumulative as of the client’s latest report, not final. Cases with a 6+ month period (n=13) are not included in the table: most are interim reports after breaks in the program and understate the real picture.
Our data vs a clinical trial
For context, we compare the nature of DOZA data with the randomized SURMOUNT-1 trial (tirzepatide). These are different data types — they are not directly comparable.
| SURMOUNT-1 (clinical trial) | DOZA report (real-world) | |
|---|---|---|
| Data type | Randomized controlled trial (RCT) | Self-reported client data |
| Participants | N = 2,539 | N = 163 |
| Duration | 72 weeks, fixed | Real-world, varying (3 weeks — 12 months) |
| Measurements | Standardized, in-clinic | As stated by clients, unverified |
| Outcome | Up to −20.9% of body weight (tirzepatide 15 mg) | Median −5.1% of body weight (n=33, interim) |
These are different data types — they are not directly comparable. An RCT measures drug efficacy under controlled conditions over a fixed period; our report shows real interim results of support-program clients. SURMOUNT-1 source: Jastreboff et al., NEJM 2022.
Which products achieved the results
Mounjaro: 141 cases; Ozempic: 14 cases; Retatrutide: 13 cases; Biopatid: 10 cases; Other: 2 cases
Number of cases mentioning a product in the dialogue. Some clients combined or switched between products, so the sum exceeds 163. The total −1,026 kg reflects DOZA support-program clients overall, not the efficacy of any single product. Source: DOZA Telegram dialogues, August 2025 – July 2026.

Methodology
The full DOZA support conversation archive was analyzed: 1,272 dialogues, 67,918 text messages between 22.08.2025 and 15.07.2026. Of these, 908 dialogues were clients with confirmed orders. Client messages stating a numeric result ("lost N kg", "minus N", "from X to Y kg", cm measurements) were extracted automatically. Excluded: goal statements, results achieved before joining DOZA, questions, and messages about third parties. A client’s result is defined as the maximum weight loss they confirmed as of their latest report. Duplicates were removed. All data was anonymized: names, usernames and contacts were not used.
163 rows with no personal data: report month, weight loss, starting weight (where known), % of body weight, observation period, products. License: CC BY-NC-ND 4.0.

Frequently asked questions
