How long does it take for Reta to start working?

With an insulin needle it reached your system so no need to worry, just continue the weekly injections. Visible changes won't appear immediately and two hours is far too soon.

I haven't used reta myself yet. With tirz though the strongest effects hit me after at least 48 hours.

Are you serious? You should have done far more research beforehand. The initial doses let your body adjust and check for side effects, serving mainly as a test. Therapeutic impact on weight comes only after doses rise over months. Each increase needs about four weeks to reach steady levels. Start low and go slow. Any early sensation usually shows up in two or three days. Keep reading more and more.

Everyone responds differently. Some need weeks or months of gradual increases before noticing anything. In my case 2 mg reta hit my appetite hard the next day and I began dropping more than a pound weekly right away. Still, nobody I know has seen major results after only two hours. A bit of patience is needed.

After 15 minutes I lost 30 lb.

What strength was your Reta and how much BAC water did you mix in? On my first dose of 0.5mg I noticed a sour stomach within an hour followed by a severe headache that day. Nothing further after that. I would often forget I had even taken it. It took several weeks to really gauge how my body handled it. Due to the half life and buildup time, avoid raising the dose too quickly.

That's a fairly high first dose. I used 0.5 twice weekly for 12 weeks and dropped 32lbs while working out and walking daily. If the product is genuine it will start working within a few days.

Reta has behaved differently for me than tirz. Tirz kicked in within an hour at most, but reta seems to need around 24 hours. Cagri works the same way, taking 12-24 hours. Stay patient though. With tirz I got appetite suppression from the very first dose, but reta has not been like that.

I took my first dose last Sunday at 1.5mg split three times a week and actually gained 6 lbs with no drop in appetite, though I wasn't really expecting one. I've also had headaches the last three days, though today's was milder so that's progress.

I keep seeing posts where people say the reta is working yet they're starving all day and have gained two pounds. It leaves me puzzled about what makes reta better. I assume it is, but I don't see how from these reports.

How any medicine performs is a matter of probabilities, and forum posts do not represent a balanced or scientific sample of experiences.

Just stay consistent. The half life is about 5-7 days so full saturation takes five half lives. You might notice changes anywhere from the first couple of days to a couple of weeks, and it varies per person. This is not a stimulant though. One day your hunger will simply be lower and snacking won't appeal. Trust the process and well done for taking charge of your health.
