★ QUICK REFERENCE

10 mg/ml: U100: 10 Units = 1 mg | U40: 4 Units = 1 mg

Formula: mg ÷ mg/ml = ml → ml×100 = U100 Units | ml×40 = U40 Units
​

---

1. Fundamentals

Syringes show **Units only**, not mg.

U100: 100 Units = 1 ml (0.01 ml/Unit)
U40: 40 Units = 1 ml (0.025 ml/Unit)
​

---

2. Golden Rule

Syringe shows NEVER mg. Dose = Concentration × Volume. Wrong syringe = wrong dose.
​

---

3. Example (10 mg/ml)

1 mg → U100: 10 Units | U40: 4 Units

Same volume, different marks.
​

---

4. Compact Table (10 mg/ml)

• 0.5 mg → U100: 5 Units | U40: 2 Units | 0.05 ml
• 1 mg → U100: 10 Units | U40: 4 Units | 0.1 ml
• 2 mg → U100: 20 Units | U40: 8 Units | 0.2 ml
• 5 mg → U100: 50 Units | U40: 20 Units | 0.5 ml

---

5. Other Concentrations

5 mg/ml: 1 mg = U100 **20 Units** | U40 **8 Units**
2.5 mg/ml: 1 mg = U100 **40 Units** | U40 **16 Units**
​

---

6. Risks

U40 + U100 math = **2.5× overdose**
U100 + U40 math = **40% underdose**
​

---

7. Formula

1. mg ÷ ml = mg/ml
2. Desired mg ÷ mg/ml = ml
3. ml×100 = U100 Units | ml×40 = U40 Units
​

---

8. Best Practices

• U100 as default
• Double-check syringe + concentration
• Use calculator + label vials
• Sterile technique

---

9. Mistakes to Avoid

• Fixed Units without checking
• Mixing U100/U40
• Wrong reconstitution or dosing by feel

---

FINAL SUMMARY

U100 = 100 Units/ml | U40 = 40 Units/ml

**At 10 mg/ml**: 10 Units (U100) = 4 Units (U40) = 1 mg

Always calculate ml first.

@ICL translate in simple words please...

@ICL translate in simple words please...

basically

2 types of insulin syringes (for insulin, gh etc)

u40 and u100

you know people say blah blah blah shit like "rate stack 12iu hgh everyday"

So that syringe with u40

the 4 units inside that is 1mg of hgh

for the u100, thats 10 units for 1 mg of hgh

as we know 1mg = 3iu (iu and units are different, iu is internationally agreed on unit, unit is just used in anything)

So lets say our retard running 12iu gh has 4mg of hgh (bc 1mg is 3 iu, basic math can tell us 3 iu is 1 mg, and more basic math tells us 12 iu is 4mg)

In that u40 syringe thats 4 units for 1mg, so he gotta pin 16 units because 4*4 (mg dose*unit= needed dose)

For a u100 syringe our retard needs 40 units, since 4 (mg dose) * 10 (units)

The reason they are different is one syringe's tube is tighter so it fills up laterally very quickly

even though 40 units of GH sounds insane, for a u100 syringe that's basically 12iu/4mg of HGH which is normal

Btw I prefer U100

 

[DavidePollo]

I think it's pretty common sense that the amount of drug you inject depends on how diluted your concentration is
No shit siringes does not measure weight (mg) but volume
I guess Americans are just retarded cause it's pretty basic knowledge to be able to distinguish between the twos
