A Note Before You Begin
Weight loss injections have become one of the most searched health topics of the past three years, and for good reason. GLP-1 receptor agonists such as semaglutide and tirzepatide have delivered clinical results that were once considered impossible without surgery: 15 to 22 percent total body weight loss in randomised controlled trials, with meaningful improvements in blood sugar, blood pressure, and cardiovascular risk markers.
The surge in demand has created a parallel surge in clinics, medspas, and online platforms offering these medications, often with minimal screening, no follow-up protocol, and little regard for the long-term health of the patient. In the Philippines and across much of Southeast Asia, GLP-1 medications are increasingly available through channels that range from rigorous physician-led programmes to loosely supervised walk-in consultations where the medication is the entire product. The gap matters, because the questions a clinic does not ask you, and that you do not ask them, can have real consequences for your health, your muscle mass, your metabolism, and your long-term results.
Before you schedule that first injection, here are seven questions every patient should bring into the room. Most clinics will not raise them. A good physician will answer all of them without hesitation.
This article is for informational purposes only and does not constitute medical advice. Weight loss medications are prescription therapies that require individualised clinical evaluation. Always consult a licensed physician before starting any pharmacological weight management programme.
Why These Seven Questions Matter
The seven questions below are not a stress test. They are the basic clinical checklist that distinguishes a physician-supervised weight management programme from a medication dispensary. The medication itself is essentially the same product across clinics. The clinical infrastructure around it is what differs, and that infrastructure determines whether you achieve durable results, preserve your metabolic health, and exit the programme well.
A clinic that welcomes these questions is one that has built a programme around your health. A clinic that deflects, dismisses, or cannot answer them is one worth walking away from. You are not being a difficult patient by asking. You are being a careful one.
The Seven Questions to Ask Before a Weight Loss Injection
1. Am I Actually a Clinical Candidate for This Medication?
This sounds obvious. It is not. GLP-1 receptor agonists are approved for adults with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or dyslipidaemia. These are clinical thresholds, not aesthetic ones. A physician who does not confirm your eligibility against these criteria before prescribing is not practising weight management medicine. They are dispensing a product.
Your physician should also review your personal and family medical history for contraindications, including a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2), both of which are absolute contraindications to GLP-1 use. A history of pancreatitis, severe gastrointestinal conditions, and certain kidney disorders also require careful evaluation before prescribing.
If a clinic offers to prescribe after a five-minute online form, that is not a clinical evaluation. That is a transaction.
2. What Baseline Labs and Assessments Will You Run Before We Start?
A legitimate weight management programme does not begin with a prescription. It begins with data. Baseline assessments should typically include:
Fasting blood glucose and HbA1c, to identify pre-existing diabetes or pre-diabetes.
Lipid panel, to assess cardiovascular risk and establish a baseline for comparison.
Thyroid function tests (TSH, free T4), given the thyroid-related contraindications of GLP-1 medications.
Liver and kidney function markers, since these medications are metabolised and excreted through these organs.
Body composition assessment using bioelectrical impedance analysis (InBody) or 3D body scanning (Styku), not just BMI or scale weight, since the fat-versus-lean ratio is what calibrates the programme.
Blood pressure and resting heart rate, as baseline cardiovascular markers.
Some programmes also assess fasting insulin, HOMA-IR, and inflammatory markers for a fuller metabolic picture. If a clinic proposes to start injections without any of these, or dismisses them as unnecessary, the programme is not clinically designed. It is commercially designed.
3. How Will You Monitor My Muscle Mass Throughout This Programme?
This is the question most clinics skip, and it is arguably the most important one for long-term health.
GLP-1 medications reduce appetite significantly. That is the mechanism. But appetite suppression is not selective. It reduces caloric intake broadly, which, without specific nutritional and training protocols, leads to loss of both fat and muscle. Studies on semaglutide including the STEP trials showed that a meaningful portion of total weight lost came from lean mass rather than fat. In some cohorts, muscle loss accounted for approximately 25 to 39 percent of total weight lost, a proportion that carries significant metabolic consequences.
A physician-led programme should set a specific protein intake target (typically 1.2 to 1.6 grams per kilogram of ideal body weight per day), recommend or co-design a resistance training protocol, use body composition assessment tools at regular intervals throughout treatment, and adjust dosing or nutritional strategy if muscle loss is detected.
If your clinic tracks only your scale weight, it is not tracking your health.
4. What Is the Dose Titration Plan?
GLP-1 receptor agonists are not one-size-fits-all. Both semaglutide and tirzepatide follow structured titration schedules, beginning at low doses and increasing incrementally over weeks to months, specifically to minimise gastrointestinal side effects (nausea, vomiting, diarrhoea, constipation) while the body adjusts.
Semaglutide typically starts at 0.25 mg weekly and titrates up over 16 to 20 weeks to a maintenance dose of 2.4 mg weekly for weight management indications. Tirzepatide follows a similar escalation pattern, starting at 2.5 mg weekly and increasing in 2.5 mg steps every four weeks. The pacing matters as much as the medication.
Specific questions to ask your physician include: What is my starting dose, and what is the planned titration schedule? Who manages dose adjustments, and how? What symptoms warrant pausing or reducing my dose? Will my dose be individualised based on how I respond, or is everyone given the same protocol?
A clinic that starts every patient at the same dose without individualised titration is not practising precision medicine. It is running a protocol designed for operational simplicity, not clinical safety.
5. Is This Medication Authentic and Properly Sourced?
This question is not paranoia. It is due diligence.
The global explosion in GLP-1 demand has been accompanied by a parallel rise in counterfeit medications, improperly stored products, and unregulated compounded versions that vary significantly in potency, sterility, and composition. In multiple countries including the Philippines, regulatory authorities have issued warnings about unregistered or adulterated semaglutide products circulating through informal channels.
You are entitled to ask: Is this medication registered with the Philippine FDA? Is it sourced directly from the licensed manufacturer or an authorised local distributor? Can you provide documentation of cold-chain storage compliance?
Authentic branded GLP-1 medications come in manufacturer-sealed auto-injector pens with batch numbers verifiable through the manufacturer. If the product cannot be traced to a legitimate supply chain, the risk you are taking extends well beyond the known side effect profile of the medication itself.
6. What Is the Nutritional Protocol That Accompanies the Injection?
The injection is not the programme. It is one tool within a programme.
GLP-1 medications work by reducing appetite, slowing gastric emptying, and improving satiety signals. But what you eat (the quality, composition, and timing of nutrition) determines whether the caloric reduction translates into fat loss, muscle loss, or both.
Your physician or the programme's registered nutritionist should provide a macro framework specific to your body composition goals and current metabolic state, guidance on protein distribution across meals rather than just total daily intake, strategies for managing reduced appetite without falling below safe caloric thresholds, and micronutrient supplementation recommendations, since appetite suppression can cause inadvertent deficiency.
A weight management programme without a nutrition component is a medication delivery service. Nutrition is not supplementary. It is structurally necessary to the clinical outcome.
7. What Is the Exit Strategy, and What Happens When I Stop?
This is the question patients almost never ask, and the one with the most significant long-term implications.
GLP-1 medications are not indefinite treatments for most patients. Current evidence from the STEP 4 trial on semaglutide and similar studies on tirzepatide shows clearly that when these medications are discontinued without a maintenance strategy in place, a substantial portion of lost weight is regained. In some cohorts, over two-thirds within one year of stopping.
Before you start, your physician should be able to answer four questions. What is the intended duration of this programme? How will we transition off the medication when the time comes? What behavioural, nutritional, and exercise habits are being built during the programme to sustain results afterward? And if I cannot afford to continue long-term, what is the clinical plan for a managed exit?
A programme that sells injections without addressing the off-ramp is not designing for your success. It is designing for your continued enrolment.
Frequently Asked Questions
What are the most important questions to ask before starting a weight loss injection?
The most important questions cover clinical candidacy (are you medically eligible?), baseline lab requirements, how muscle mass will be monitored, what the dose titration plan looks like, whether the medication is authentically sourced, what nutritional protocol accompanies the injection, and what the exit strategy is when the programme ends.
Is it safe to start a GLP-1 injection without a physician's supervision?
No. GLP-1 receptor agonists are prescription medications with real contraindications, dosing requirements, and potential side effects that require medical supervision. Unsupervised use significantly increases the risk of adverse effects, muscle loss, nutritional deficiency, and inappropriate dosing.
How do I know if a weight loss clinic is legitimate?
A legitimate clinic will conduct a medical evaluation before prescribing, order baseline laboratory tests, provide a structured titration plan, monitor body composition rather than just scale weight, source medications through verified regulatory channels, and offer a clear long-term management strategy including what happens when you stop.
Will I gain the weight back after stopping a weight loss injection?
Clinical evidence from the STEP 4 trial shows that without a maintenance strategy, a significant portion of weight lost on semaglutide can be regained after stopping. This is why physician-supervised programmes should include behavioural, nutritional, and exercise components designed to sustain results, not just the medication itself.
What lab tests should be done before starting a GLP-1 medication?
Before starting a GLP-1 receptor agonist, baseline labs should typically include fasting blood glucose, HbA1c, a lipid panel, thyroid function tests (TSH), liver and kidney function markers, and a body composition assessment. Blood pressure and resting heart rate should also be documented.
Can I take weight loss injections if I have a thyroid condition?
It depends on the specific condition. GLP-1 receptor agonists are contraindicated in individuals with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2). Other thyroid conditions require individualised physician evaluation. Always disclose your full medical history before starting.
Where can I find a physician-led programme in Metro Manila?
Jan Medical Group offers the SHAPE programme, a physician-supervised GLP-1-based weight management programme, at its BGC branch (Park Triangle Mall, Taguig) and Quezon City branch (Bengar Building, Del Monte Avenue, Brgy. Manresa). A consultation with Dr. Jan Paolo Dipasupil is the first step, and every patient receives a full diagnostic workup before any prescription is issued.
How to Use These Questions
GLP-1 receptor agonists represent a genuine clinical breakthrough in the management of obesity and metabolic disease. For the right patients, in the right programme, with the right medical oversight, they can be life-changing, not just in terms of the number on the scale, but in terms of cardiovascular risk reduction, insulin sensitivity, and quality of life.
But they are powerful prescription medications operating inside complex human physiology. They are not wellness products. They are not lifestyle supplements. And the clinics dispensing them are not all equipped, or motivated, to manage the full clinical picture.
The seven questions in this article are not designed to make you a harder patient. They are designed to help you find a physician and a programme worthy of the trust you are placing in them. Take them with you to your consultation. Listen carefully to which ones are answered thoroughly, which ones are deflected, and which ones the clinic clearly has not thought through.
A clinic that welcomes these questions and answers them without hesitation is one that has built a programme around your health. One that cannot, or will not, is one worth walking away from. You deserve both the result and the process that gets you there safely.
