GLP-1 and tirzepatide support by a certified endocrinologist
A tirzepatide, semaglutide or other GLP-1 course is best taken under medical supervision. At DOZA, support is led by Valentyna Tytorenko — a diploma-certified endocrinologist and certified dietitian and nutritionist: a personalised lab checklist, results review, dose titration and nutrition correction — even if you bought Mounjaro, Ozempic, Biopatid or another medication elsewhere.

One-off consultation with lab review — 1 200 ₴: history, lab checklist, written protocol and 7 days of chat follow-up.

Which medications the support covers
One endocrinologist — support across the full DOZA GLP portfolio. Below are informational product pages (no purchase required from us).
Mounjaro
tirzepatide · dual GIP/GLP-1 agonist
Endocrinologist support on a Mounjaro course: labs, titration, nutrition — even if you bought the pen elsewhere.
Ozempic
semaglutide · GLP-1 agonist
The same support format for people already on Ozempic: lab review and titration control.
Biopatid
tirzepatide · branded analogue
Biopatid support uses the same lab panel and titration logic as other tirzepatide brands.
Tirzetta and other tirzepatide brands
tirzepatide · INN overview
If you already have the medication under another brand — support works with no purchase-location lock-in.
Retatrutide
research · triple agonist · not FDA/EMA/MOH approved
Research course: support focused on labs and cautious titration. Not an approved medicine.

Which lab tests to take before GLP-1 (tirzepatide, semaglutide)
The baseline panel the DOZA endocrinologist recommends checking before starting a tirzepatide or semaglutide course. During the consultation the list is adapted to your history — some items may be unnecessary, others may be added.
HbA1c (glycated hemoglobin)
Average glucose over the last ~3 months — the baseline carbohydrate-metabolism marker.
Fasting glucose and insulin (HOMA-IR)
The insulin-resistance index: it shapes the starting strategy and expectations from the course.
Lipase
A pancreatic enzyme — baseline before the start and a control point if abdominal pain appears.
TSH
Thyroid function directly affects weight, energy and the outcome of the course.
Calcitonin
Checked before starting GLP-1-class medicines — a manufacturer precaution for family history of medullary thyroid cancer.
Ferritin
Iron stores: low ferritin during a calorie deficit is a frequent cause of fatigue and hair loss.
Vitamin D
Commonly deficient; affects energy, immunity and mood — corrected in parallel with the course.
Vitamin B12
Critical with reduced appetite and small meal volumes — which is exactly how tirzepatide and semaglutide work.
Lipid panel
Cholesterol and triglycerides at baseline — to track improvements over the course.
💡 Already have recent lab results? Great — if they are under 2–3 months old, the endocrinologist reviews them as is; no need to retest.
Frequently asked questions about tirzepatide and GLP-1 support
The baseline panel: HbA1c, fasting glucose and insulin (HOMA-IR index), lipase, TSH, calcitonin, ferritin, vitamin D, B12 and a lipid panel. The exact list depends on your history — during the consultation the endocrinologist builds a personalised checklist and explains what is checked and why.
