About Vita Reta 10mg
Reta is an investigational once-weekly peptide that acts on three receptors: GLP-1, GIP and glucagon. It is in late-stage trials and not approved anywhere.
Vita: Each order is one vial holding 10 mg of freeze-dried powder. Mix it with bacteriostatic water before use.
Commonly used for
- Research into weight loss and metabolic disease
How it works
GLP-1 and GIP reduce appetite and improve insulin release; the glucagon component raises energy use and liver fat burning. In a 48-week phase 2 trial, the top dose produced average weight loss of about 24%.
Half-life: about 6 days.
Release profile
How levels rise and fall after a single dose, based on a half-life of about 6 days. Each mark on the axis is one half-life; after about five, almost none is left.
An illustration from the half-life only; real levels vary with dose, how it is given and the person.
Clinical reference dose
Clinical reference: phase 2 trials started at 2 mg once a week and stepped up every 4 weeks to target doses of 4–12 mg a week. It is not approved for any use.
Mixing: adding 2 ml of bacteriostatic water to this 10 mg vial gives 5 mg per ml. On a U-100 insulin syringe, 10 units (0.1 ml) then holds 0.5 mg.
Heart rate rose in trials, more at higher doses.
These are reference amounts from labels and clinical studies, not a personal recommendation. A doctor sets the right dose for you, using your bloodwork.

Injection sites
Reta 10mg comes as a freeze-dried powder. Once it is mixed with bacteriostatic water, peptides like this are usually given subcutaneously (subQ): into the fat just under the skin with a short insulin needle, not into muscle.
- Muscle
- Subcutaneous fat of the belly
- Group
- Abdominal wall
- Volume (nursing reference)
- Up to about 1 ml per site
- Needle
- 4–13 mm insulin needle, 29–31G
Finding it. Anywhere on the belly at least 5 cm (2 in) from the navel, avoiding scars, stretch marks and the belt line. Pinch a fold of skin and inject into the fold.
Why people choose it. The most-used subcutaneous site: the most fat, easy to see and reach, and absorption is steady. It is the first site listed on the labels of weekly GLP-1 pens.
Watch out. Move each injection at least 2–3 cm from the last one to avoid lumps (lipohypertrophy).
- Muscle
- Subcutaneous fat of the thigh
- Group
- Thigh
- Volume (nursing reference)
- Up to about 1 ml per site
- Needle
- 4–13 mm insulin needle, 29–31G
Finding it. The middle of the front of the thigh, a hand-width below the hip and above the knee.
Why people choose it. Easy to reach seated and a good second site to rotate with the belly.
Watch out. Absorption can be a little slower than the belly, and heavy leg exercise straight after may speed it up.
- Muscle
- Subcutaneous fat over the triceps
- Group
- Upper arm
- Volume (nursing reference)
- Up to about 1 ml per site
- Needle
- 4–13 mm insulin needle, 29–31G
Finding it. The fleshy back of the upper arm, halfway between the shoulder and the elbow.
Why people choose it. Adds a third site to rotate through, so each spot gets more rest.
Watch out. Hard to pinch and reach on yourself; most people need a helper here.
Why these sites for Reta 10mg
Subcutaneous (subQ)- Same three sites as the pens. Weekly medicines in this class are labelled for the abdomen, thigh or upper arm. Pick one area and move to a new spot each week.
- Belly first. The abdomen has the most fat and the steadiest absorption, and you can see what you are doing. The thigh and back of the arm are there to rotate into.
- Small volumes, short needle. SubQ injections are small (around 1 ml or less per spot). An insulin syringe (4–13 mm) reaches the fat without touching muscle; pinch the skin if you are lean.
- Rotate every time. Move each injection 2–3 cm from the last. Repeating one spot causes hard lumps under the skin that absorb unevenly.
Every time: wash your hands, wipe the vial top and the skin with alcohol and let it dry, use a new sterile needle and syringe, and never share. Get medical help for spreading redness, heat, swelling, pus, fever, numbness or pain that keeps getting worse. This is general reference information from standard nursing injection guidance, not medical advice; a pharmacist or nurse can show you the technique in person.
