GLP-1 & Weight Loss Research Guides
The three most researched weight loss peptides available in the Philippines — with protocol tables, dosing guides, and comparison data.
Tirzepatide ⭐
GLP-1 + GIP Dual Agonist · Most Effective Weight Loss Peptide Available
- Dual GLP-1 and GIP receptor agonist — stronger than semaglutide alone
- Start at 2.5mg/week, titrate up every 4 weeks as tolerated
- Available as Japan-import Mounjaro pens (5mg/dose) — most popular in PH
- WADA-prohibited for competitive athletes
Semaglutide
GLP-1 Receptor Agonist · Ozempic Generic · Proven Clinical Data
- GLP-1 receptor agonist with robust clinical trial data (STEP trials)
- Start at 0.25mg/week, titrate monthly to maintenance 2.4mg
- Available as lyophilized powder or pre-filled pens
- More established side effect profile vs tirzepatide
Retatrutide
GLP-1 + GIP + Glucagon Triple Agonist · Next-Generation Weight Loss
- Triple agonist — GLP-1, GIP, and glucagon receptors simultaneously
- Phase 2 data shows ~24% body weight reduction — highest of all GLP-1 class
- Research compound only — not yet FDA approved
- Less nausea reported vs semaglutide at equivalent weight loss

Research FAQs
Ozempic is Novo Nordisk's branded pharmaceutical-grade semaglutide with FDA and Philippine FDA approval. Generic/research semaglutide is the same molecule but produced without pharmaceutical manufacturing oversight. Generic versions have not undergone clinical trial regulatory review. The key difference for researchers: branded Ozempic comes with consistent dosing in pre-filled pens; generic comes as lyophilized powder you reconstitute yourself. Purity verification via COA (an independent lab) is essential for generic versions.
A high-quality lyophilized peptide should have:
- White, fluffy "cake" appearance — not collapsed, melted, or discolored
- Clear solution after reconstitution with no persistent particles
- Matching COA with correct molecular weight and purity ≥99%
- Properly sealed vial with intact rubber stopper
- Storage conditions maintained (most require refrigeration 2–8°C)
Use bacteriostatic water (BW) for multi-dose vials — the 0.9% benzyl alcohol preservative keeps reconstituted peptides stable for 28–42 days refrigerated. Use sterile water only for single-dose use (use immediately after reconstitution). For GLP-1 research protocols where you dose weekly, BW is almost always the correct choice. Never use tap water or saline for reconstitution.
For weekly GLP-1 injections, the day of the week matters more than the time of day. Most researchers pick a consistent day (e.g., every Monday). Morning vs evening injections show no significant difference in efficacy. Injecting with or without food also makes minimal difference — though some find nausea slightly better managed by injecting before bed on an empty stomach. Subcutaneous injection in abdomen, thigh, or upper arm are all equivalent.
Not necessarily. 2.5mg is the starting dose designed to minimize side effects, not maximize weight loss. Clinical trials show 2.5mg produces modest effects — the target dose for weight loss efficacy is 10–15mg/week after gradual titration over 4–5 months. Verify your compound with COA first, then evaluate: are you titrating up on schedule? Is caloric intake actually reduced? GLP-1 works primarily by reducing appetite — it requires dietary changes to produce results.
Verify COAs by: (1) checking the lab name matches a known testing service (an independent lab, Simec, or similar), (2) cross-referencing the certificate number on the lab's website if available, (3) checking that the molecular weight on the COA matches the known MW for the peptide, and (4) looking for HPLC chromatography data — a real COA includes an actual chromatogram image, not just a number. PDFs that only list a percentage with no supporting data are suspicious.
