Reta is the store’s name for a triple agonist that acts on GIP, GLP-1 and glucagon receptors. It is in clinical trials for weight management and is not approved anywhere.
Adding glucagon-receptor activity to the GIP and GLP-1 effects is thought to raise energy use as well as lower appetite. Its half-life is about six days.
Phase 2 trials started at 2 mg once a week and stepped up every four weeks to target amounts of 4 to 12 mg a week. It has no approval for any use.
Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Strength used: 10 mg per vial
Reta RT-3 10mg is a freeze-dried powder. After mixing with bacteriostatic water, compounds like this are usually injected subcutaneously (subQ): into the fat just under the skin with a short insulin needle.
Finding it. Anywhere on the belly at least 5 cm from the navel, avoiding scars and the belt line. Pinch a fold of skin and inject into it.
Why it is used. The most-used subcutaneous site: easy to see, plenty of fat and steady absorption. Weekly GLP-1 pens list it first.
Watch out. Move each injection 2 to 3 cm from the last to avoid hard lumps.
Finding it. The middle of the front of the thigh, a hand-width below the hip and a hand-width above the knee.
Why it is used. 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.
Finding it. The fleshy back of the upper arm, halfway between shoulder and elbow.
Why it is used. A third site to rotate through so each spot rests longer.
Watch out. Hard to pinch and reach on yourself; a helper makes it easier.
Every time: wash your hands, wipe the vial stopper and skin with alcohol, use a new sterile needle and syringe, and never share.

Nausea, vomiting and diarrhea were the most common in trials.
