How much FECO should a complete beginner take?

Start with a rice-grain sized amount (5–10 mg) once daily. This is the absolute minimum effective dose that allows your body to adjust to the cannabinoids. Most beginners feel comfortable increasing after 3–7 days.

What's the difference between FECO and RSO dosing?

FECO and RSO are similar full-spectrum extracts, but FECO is often slightly less potent depending on the strain and extraction method. Start with the same rice-grain protocol for FECO, but you may reach your therapeutic dose slightly faster.

Can I take FECO sublingually?

Yes, sublingual dosing (under the tongue) is excellent for FECO. Place the oil under your tongue for 30–60 seconds before swallowing. Effects onset in 20–45 minutes, faster than oral dosing.

How do I measure FECO from a syringe accurately?

FECO syringes have measurement markings. For a rice-grain dose, dispense just 5–10 mg (the oil should be barely visible). Many users warm the syringe slightly under warm water to improve dispensing.

Should I take FECO with food?

Yes, always pair FECO with fatty foods (peanut butter, coconut oil, avocado, full-fat yogurt). Fat increases cannabinoid absorption by 3–5x, making your dose more effective.

How long until I feel FECO effects?

Oral FECO: 30–90 minutes onset, peak at 2–3 hours. Sublingual: 20–45 minutes onset. Effects typically last 4–8 hours depending on dose and individual metabolism.

What if I accidentally take too much FECO?

FECO overdose is not dangerous, but uncomfortable. If you feel too high: stay calm, drink water, rest, and use CBD if available (CBD counteracts THC). Effects will subside in 4–8 hours.

Can I use FECO topically?

Yes. FECO works well for topical application on skin irritations, muscle soreness, and localized pain. No psychoactive effects when applied to skin. Mix with a carrier oil for better absorption.

How should I store FECO oil?

Store FECO syringes in a cool, dark place (60–70°F ideal). Refrigeration extends shelf life. Keep away from direct sunlight and heat, which can degrade cannabinoids. Properly stored FECO lasts 6–12 months.

Is FECO better than smoking or vaping?

FECO provides full-spectrum effects (full cannabinoid and terpene profile), unlike isolated THC products. Effects are longer-lasting and more medicinal. However, onset is slower. Choose based on your needs.

What Is FECO? Complete Overview

Full Extract Cannabis Oil (FECO) is a potent full-spectrum cannabis concentrate that preserves all cannabinoids (THC, CBD, CBG, CBN) and terpenes from the plant. Unlike isolated products, FECO provides the "entourage effect"—all compounds working together for enhanced therapeutic benefits.

FECO is extremely concentrated—typically 50–90% THC content depending on the source plant. The potency is why precise dosing is absolutely critical. A rice-grain sized dose (5–10 mg) can produce significant effects, making FECO unsuitable for casual use.

Because of its concentrated nature, FECO comes in syringes that allow accurate measurement. The thick oil requires careful dispensing, making the syringe format ideal for safe, controlled dosing.

The "Start Low, Go Slow" Principles

Begin with a rice-grain dose

5–10 mg is the absolute starting point

Wait 3–7 days before increasing

Allow body adaptation between dose changes

Use with fatty foods

Fat increases absorption and makes effects more stable

Track your response

Note effects to find your ideal dose

Consistency matters

Regular dosing produces better results than sporadic

Stop if uncomfortable

You can always increase, but reducing takes time

FECO Dosage Levels by Experience

Experience Level	Dose per Use	Daily Frequency	Timeline	Notes
Beginner	5–10 mg (rice-grain sized)	Once daily	Days 1–7	Start with smallest possible amount
Beginner+	10–15 mg	1–2 times daily	Days 8–21	Only increase if fully comfortable
Moderate	15–25 mg	1–2 times daily	Weeks 4–8	Established tolerance level
Advanced	25–50 mg	2–3 times daily	Week 9+	Experienced users only

Finding Your Perfect FECO Dose

Everyone's tolerance is different. Some people feel effects at 5 mg, others need 25 mg or more. Start at the beginner level and adjust based on how you feel over 1–2 weeks.

• Week 1: Rice grain (5–10 mg) once daily at bedtime
• Week 2–3: Increase to 10–15 mg or add a second dose
• Week 4+: Adjust upward or stay at current level if satisfied
• Goal: Find the minimum effective dose that provides desired effects

Most users find their ideal dose between 15–25 mg per day. Advanced users may take 50+ mg, but this is not necessary for therapeutic benefits.

How to Take FECO: Consumption Methods

Oral (Swallowing)

Dispense from syringe directly into mouth or mix with food. Effects onset in 30–90 minutes, peak at 2–3 hours, last 4–8 hours.

✓ Longest-lasting effects
✓ Most discreet method
✓ Great for consistent daily dosing
✗ Slowest onset

Sublingual (Under the Tongue)

Place oil under tongue for 30–60 seconds, then swallow. Faster absorption via oral mucosa. Onset in 20–45 minutes.

✓ Faster onset than oral
✓ Direct mucosa absorption
✓ Good for acute symptom relief
✗ Taste can be strong

Mixed with Food

Mix FECO with yogurt, honey, peanut butter, or smoothies. Fat in food increases absorption by 3–5x, making your dose more effective.

✓ Masks the strong taste
✓ Increases bioavailability dramatically
✓ Easier to measure precise doses
✗ Still slow onset

Topical Application

Mix with carrier oil (coconut, jojoba) and apply to skin for localized relief. No psychoactive effects when absorbed through skin.

✓ No psychoactive effects
✓ Excellent for inflammation, pain
✓ Precise localized relief
✗ Slower absorption

FECO Syringe Dosing: Pro Tips

1.Warm the syringe: Hold the FECO syringe under warm (not hot) water for 30 seconds. Warmth makes the oil flow easier for precise measurement.
2.Read the markings: Most FECO syringes have 0.5g to 1g total capacity with measurement lines. For 10 mg, you'll dispense a tiny amount barely visible.
3.Use the plunger slowly: Gently push the plunger. Jerky movements can cause over-dispensing.
4.Dispense onto a parchment square: For tiny doses, dispense onto parchment paper to see exactly how much you're using.
5.Store properly: Keep syringe in cool, dark place. Refrigeration extends shelf life. Do not expose to direct heat or sunlight.
6.Consider capsule filling: Some users fill empty vegetable capsules with FECO for easy, consistent dosing.
