## Tirzepatide
#### Experience
- Generally don't feel hungry or think about food.
- Not unpleasant to eat. Food tastes the same, but doesn't trigger overpowering cravings.
#### Usage
- Weekly injections — delivered either as pre-loaded syringes (sometimes in plastic "pen"-style housing to make it less scary) or in the form of bottles + package of new syringes.
- Injections are subcutaneous, which are easy to do / hard to screw up, and don't hurt much.
- Effects kick in as soon as a few hours later, but take 24-48hrs to reach full strength — and then wane near the end of the 7-day cycle.
- Resistance builds, so dosage must be increased periodically.
- You can pause / delay the next shot whenever you like for as long as you like, such is if you want to enjoy eating more on a vacation, or to drop your resistance back down to reduce the needed dose when you resume.
> [!NOTE] Understanding Labels
> 1 unit = 0.01mL. If a bottles contains 2mL of liquid, that's' 200 units. A typical syringe can draw 60-100 units (0.6-1.0 mL).
###### Anecdotal Effectiveness Chart

| @ Injection | 0% |
| Injection + 1 day | 80-100% |
| Injection + 2 days | 100% |
| Injection + 3 days | 100% |
| Injection + 4 days | 97% |
| Injection + 5 days | 90% |

#### Injection Tips
- Rotate injection sites each week to avoid irritation or tissue damage.
- Abdomen: At least 2 inches away from the belly button, as this area has a good layer of fat for absorption.
- Thigh: The upper, outer part of the thigh, where there’s enough subcutaneous tissue.
- Upper arm: The back or outer part of the upper arm, though this may be harder to self-inject without assistance.
- Avoid injecting into areas that are bruised, tender, scarred, or near moles or tattoos.
- Clean the site with an alcohol swab before injecting. (Also clean the needle.)

#### Lifestyle Tips
- Drink lots of water.
- Get lots of soluable fiber — 25g for women, 38g for men. *([pills](https://amazon.com/dp/B003VV05IM/), oats, beans, chia seeds)*
- Eat mostly protein — at least 1g / kg of body weight — up to 1.6g / kg if you can.
- Eat small amounts frequently throughout the day to keep metabolism active.
- Lift heavy weights to increase or at least retain muscle.
- Don't go too fast for too long — go slow or take breaks for skin to heal / shrink.

## Market
Internet companies partner with doctors to issue prescriptions to online customers, and partner with real-world pharmacies (usually near the internet company) to prepare the medicine. An online search for "tirzepatide" will produce dozens of results of simple marketing-heavy websites that look scammy, but are actually legitimate. *(At least, I haven't personally encountered fraud yet, either myself or through my social network.)*
If you're getting a medicine that has not yet been approved purely for weightloss, such as Tirzepatide, pharmacies will mix it with vitamins and other beneficial ingredients in order to pass legal muster.
