Question 1

What are peptides?

Accepted Answer

Peptides are short chains of amino acids (the building blocks of proteins). In the context of this site, we focus on bioactive peptides that signal specific effects in the body: GLP-1 agonists for weight loss, healing peptides for tissue repair, growth hormone secretagogues for recovery and muscle, etc. Most are administered by injection (sub-q or IM).

Question 2

Are peptides legal in the Philippines?

Accepted Answer

Most research peptides exist in a grey area. They're not explicitly illegal to possess for personal research use, but they're also not FDA-approved as medicines. Clinics sometimes prescribe compounded versions. The DIY route (ordering for personal use) is common but technically unregulated. Always check current local regulations.

Question 3

Do I need a prescription?

Accepted Answer

If you go through a clinic, they'll prescribe peptides and source them for you. If you're sourcing independently (DIY route), most research peptides dont require a prescription, but this varies by compound and supplier. GLP-1s like semaglutide may require prescriptions in some contexts.

Question 4

Is this safe? Is this medical advice?

Accepted Answer

This site is educational only. Nothing here is medical advice. Peptides carry risks. You should work with a qualified healthcare professional before starting any protocol. The information here helps you research and ask informed questions, but it doesnt replace professional medical guidance.

Question 5

How do I reconstitute peptides?

Accepted Answer

Reconstitution means mixing lyophilized (powder) peptide with bacteriostatic water to create an injectable solution. You add a specific amount of bac water to the vial, then calculate how many units on your insulin syringe = your desired dose. Use the reconstitution calculator on this site to do the math automatically. Full walkthrough in the beginner guide.

Question 6

Bacteriostatic water vs sterile water?

Accepted Answer

Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, allowing you to draw multiple doses from the same vial over weeks. Sterile water has no preservative, so it's single-use only (entire vial must be used at once). For multi-dose vials, always use bac water.

Question 7

How long do reconstituted peptides last?

Accepted Answer

Most reconstituted peptides last 4-6 weeks in the fridge (2-8°C). Some (like TB-500) can go longer. Once mixed, always store in the fridge, never at room temp (especially not in PH heat). Never freeze reconstituted peptides. If the solution looks cloudy or discolored, toss it.

Question 8

Where do I inject?

Accepted Answer

Most peptides are injected sub-q (subcutaneous, into the fat layer just under the skin). Common sites: lower abdomen (around belly button area), outer thigh, upper buttock. Rotate sites to avoid scar tissue buildup. A few compounds are injected IM (intramuscular), but sub-q is the default.

Question 9

Best time to inject GLP-1s?

Accepted Answer

Doesnt matter much. Pick a consistent time. Many people pin in the evening so any nausea happens while sleeping. Once-weekly GLP-1s (sema, tirz, reta) can be pinned any day of the week, just keep the same day each week.

Question 10

How do I store peptides in PH heat?

Accepted Answer

Lyophilized (powder): fridge is best, especially in PH heat. Room temp short-term is OK but heat degrades peptides faster. Reconstituted: always fridge (2-8°C), never freezer, never room temp. In brownouts, transfer to a cooler with ice if power is out for hours. Cold chain matters more in tropical climate.

Question 11

Retatrutide vs tirzepatide vs semaglutide, which one?

Accepted Answer

Sema is the OG, single-receptor (GLP-1). Tirz is dual-receptor (GLP-1 + GIP), slightly more effective for most people. Reta is triple-receptor (GLP-1 + GIP + glucagon), most powerful but also most expensive and newest. Start with tirz if you want solid results at reasonable cost. Reta if you want maximum effect and can afford it. Sema works but tirz usually edges it out.

Question 12

Not losing weight on my GLP-1, why?

Accepted Answer

Common reasons: (1) Dose too low, titrate up. (2) Eating enough to override appetite suppression (still possible, especially calorie-dense foods). (3) Not enough protein, losing muscle instead of fat. (4) Underdosed or fake peptide (bad sourcing). (5) Metabolic adaptation, need to add movement or adjust diet. Check your actual calorie intake first.

Question 13

Will I lose muscle on GLP-1s?

Accepted Answer

You can lose muscle if you dont eat enough protein and dont resistance train. GLP-1s suppress appetite, which can lead to low protein intake and muscle loss. Fix: eat 1.6-2g protein per kg bodyweight, lift weights 3-4x/week, dont crash diet. Done right, you lose mostly fat.

Question 14

Do I need to cycle off GLP-1s?

Accepted Answer

No built-in need to cycle. Many people run GLP-1s for months or years. Some take breaks after hitting goal weight to see if appetite control sticks. Others stay on maintenance doses long-term. Its personal. If you stop, appetite will likely return, so have a plan.

Question 15

What happens when I stop GLP-1s?

Accepted Answer

Appetite comes back. Weight can rebound if you dont have eating habits and movement patterns in place. GLP-1s are tools, not magic. Use the time on them to build sustainable habits (protein focus, resistance training, realistic portions). Then when you come off, those habits carry you.

Question 16

How do I find a good supplier?

Accepted Answer

Read the sourcing principles guide on this site. Look for batch-matched COAs from third-party labs (Janoshik), proper cold chain shipping, transparent communication. Avoid suppliers with no COAs, generic COAs, or no cold chain. Specific supplier names are shared in private channels (Reddit DMs, etc.) to keep recommendations fresh.

Question 17

What is a COA?

Accepted Answer

Certificate of Analysis. A lab report showing the purity and identity of the peptide. A real COA is batch-matched (your vial batch number matches the report), from a third-party lab, and shows 95%+ purity. Generic COAs (reused across batches) are fake transparency.

Question 18

How do I know if my peptide is real?

Accepted Answer

You cant know for certain without testing it yourself, but you can reduce risk: (1) Buy from suppliers with batch-matched third-party COAs. (2) Check for proper cold chain. (3) Look for community consensus (people reporting consistent results over time). (4) If you see zero effects at proper doses, it might be fake or underdosed.
