Peptide Basics: A Beginner's Guide for the Philippines

This is the practical walkthrough for someone new to peptides in the Philippines. How to reconstitute, inject, store, and not mess it up. Start here if you've never pinned before.

Before You Start

Peptides are tools, not magic. They take time. They require consistency. If you're expecting overnight results, set that expectation aside now. Most protocols run for weeks or months before you see the full benefit.

Get bloodwork before you start anything aggressive. GLP-1s, healing peptides, most of the mild stuff probably doesn't need pre-protocol labs. But if you're running growth hormone secretagogues, or stacking multiple compounds, get a baseline. Glucose, lipids, thyroid panel at minimum. More if you're running hormonal peptides.

This is educational content. I'm not a doctor. This guide is not medical advice. If you're considering running any peptide protocol, talk to a qualified healthcare professional first. That said, if you're going to do this anyway (and most people in this space do), here's how to do it properly.

PH Context

Most people in the Filipino peptide community source independently rather than going through Makati or BGC clinics. The clinic route exists, but it tends to cost 3-5x what independent sourcing costs. This guide assumes you're sourcing on your own and need to handle reconstitution and injection yourself.

Understanding Reconstitution

Reconstitution is turning lyophilized (freeze-dried powder) peptide into injectable liquid by adding bacteriostatic water. Get the math wrong and you under-dose or over-dose. Get it right and you know exactly how much you're injecting every time.

The basic formula:

Step 1: mg in vial ÷ ml of bac water = mg per ml

Step 2: mg per ml ÷ 100 = mg per unit (on a u100 syringe)

Step 3: desired dose ÷ mg per unit = units to draw

Worked example: You have a 10mg vial of BPC-157. You add 2ml of bacteriostatic water. You want to inject 250mcg (0.25mg).

▸Step 1: 10mg ÷ 2ml = 5mg per ml
▸Step 2: 5mg ÷ 100 = 0.05mg per unit
▸Step 3: 0.25mg ÷ 0.05mg = 5 units on your syringe

So you draw to the 5-unit mark on your insulin syringe and inject. That's a 250mcg dose.

Use the Calculator

There's a reconstitution calculator on this site that does this math automatically. Plug in your vial size, water volume, and desired dose. It spits out the units to draw. I still recommend understanding the formula so you can double-check it, but the calculator saves time.

Bacteriostatic Water vs Other Water

Use bacteriostatic water for reconstitution. It contains 0.9% benzyl alcohol as a preservative, which means you can draw multiple doses from the same vial over weeks without bacterial growth. That's the whole point.

Not sterile water (that's for single-use only, no preservative). Not tap water. Not distilled water. Bacteriostatic water. If you use anything else, you risk contamination or you have to use the entire vial in one shot, which defeats the purpose of multi-dose vials.

How much bac water to add depends on the vial size and how concentrated you want the solution. Common approach: 1-3ml for a 5-10mg vial. More water = less concentrated = easier to measure small doses. Less water = more concentrated = fewer units to draw but harder to dose precisely. Most people land around 2ml for a 5mg vial or 2-3ml for a 10mg vial.

Supplies You Need

Insulin Syringes

U100, 29-31 gauge, 5/16 inch needle for sub-q. Most pharmacies carry these.

Bacteriostatic Water

For reconstitution. Available online or through research supply channels.

Alcohol Swabs

For sterilizing vial tops and injection sites. Any major drugstore chain.

Sharps Container

For safe needle disposal. Or use a thick plastic bottle with a screw cap.

Cold Storage

A small fridge or consistent cold storage for reconstituted vials.

Optional: Cooler Bag

For domestic travel with reconstituted peptides (Cebu, provincial trips).

Where to Get Supplies in PH

Insulin syringes and alcohol swabs are available at most major pharmacy chains (Mercury Drug, Watsons, South Star, etc.). You dont need a prescription. Bacteriostatic water is harder to find locally, most people order online. Sharps containers are available at medical supply stores, but honestly a thick laundry detergent bottle with a screw cap works fine for home use.

Sub-Q Injection Technique

Sub-q (subcutaneous) means injecting into the fat layer just under the skin. That's what most peptides use. A few compounds are injected intramuscularly (IM), but sub-q is the default and the focus here.

The needles are tiny (29-31 gauge). First-time nerves are normal. After a few pins it becomes routine.

Wash your hands

Soap and water. Dry them.

Swab the vial top

Use an alcohol swab on the rubber stopper of your peptide vial. Let it dry for a few seconds.

Draw your dose

Insert the needle into the vial. Pull back the plunger to the correct unit mark. Tap out any air bubbles. Draw a tiny bit more if needed to account for dead space.

Swab the injection site

Pick your spot (lower abdomen is easiest). Swab with alcohol. Let it dry.

Pinch the skin

Use your non-dominant hand to pinch a fold of skin at the injection site.

Insert the needle

Hold the syringe like a dart. Insert at a 45-degree angle (or 90 if you have more fat). The needle is short, it doesnt go deep.

Inject slowly

Push the plunger down slowly and steadily. Take 2-3 seconds. Dont rush.

Withdraw and dispose

Pull the needle out. Apply light pressure with a clean alcohol swab if needed. Dispose of the syringe in your sharps container immediately.

Common injection sites: Lower abdomen (around the belly button area, easiest and most common), outer thigh, upper buttock, back of upper arm. Abdomen is the go-to for most people.

Rotate sites. Don't pin the same spot every day. Rotate around your abdomen or switch between abdomen and thigh. Injecting the same spot repeatedly can cause scar tissue buildup or lipohypertrophy (lumps under the skin).

First Pin Tip

The anticipation is worse than the actual pin. The needles are tiny. Most people say the first one is the hardest, and by the third or fourth pin it's no big deal. If you're nervous, inject sitting down so you dont have to worry about fainting (rare, but it happens).

Storage (PH Tropical Climate)

Lyophilized (powder, unmixed): Room temp is fine short-term, but fridge is better, especially in PH heat. If you're storing powder for more than a few weeks, keep it in the fridge. High heat degrades peptides faster, and room temp in Manila can hit 30-35°C regularly.

Reconstituted (mixed with bac water): Always fridge. Never freezer (freezing destroys the peptide structure). Keep it in the main fridge compartment, not the door. The door gets temperature swings every time you open it, and that's not ideal for peptide stability.

Most reconstituted peptides stay good for 4-6 weeks in the fridge. Some (like TB-500) can go longer. If the solution looks cloudy, discolored, or has particles floating in it, toss it.

Brownout Considerations

Power outages are common in parts of the Philippines. If your fridge loses power for a few hours, your peptides are probably fine (the fridge stays cold for a while after power cuts). If it's out for a full day in the heat, that's a problem. Some people use small portable fridges with battery backup, or they keep an ice chest ready to transfer vials into during long brownouts.

Traveling domestically: If you're flying Manila to Cebu or going provincial with reconstituted peptides, use a small cooler bag with an ice pack. Keep the vials cool during transit. Most domestic flights are short enough that this works fine. Just dont leave the vials in a hot car or checked luggage in the cargo hold.

Never Freeze Reconstituted Peptides

Freezing destroys the peptide structure. Reconstituted peptides must stay refrigerated (2-8°C), never frozen. If you accidentally freeze a vial, throw it out.

Common Beginner Mistakes

Reconstitution math errors

Double-check your math. Use the calculator. If you're off by 10x, you're either wasting peptide or injecting way too much.

Storing reconstituted peptides at room temp in PH heat

Always fridge after mixing. Room temp in the Philippines will degrade most peptides within days.

Reusing needles

Never reuse needles. They dull after one use, which makes the next injection more painful and increases infection risk. One pin, one needle.

Not rotating injection sites

Rotate sites to avoid scar tissue and lumps. Pin different spots on your abdomen, or alternate between abdomen and thigh.

Starting with too high a dose

Start at the low end of the protocol range and titrate up. Most peptides work fine at conservative doses, and you can always increase if needed.

No bloodwork baseline

If you're running anything aggressive (GH secretagogues, hormonal peptides, big stacks), get baseline labs first. You need a reference point.

Next Steps

Now that you know the basics of reconstitution, injection, and storage, the next step is researching specific compounds. Head to the compound library to read about individual peptides. Each page covers mechanism, protocols, side effects, and PH-specific considerations.
