Wondering when you'll see results on semaglutide? Here's a realistic week-by-week timeline of what to expect - from appetite changes to visible weight loss.
Most patients notice the first effects within the first two weeks of starting semaglutide. The most common early sign is reduced appetite - food simply doesn't occupy as much mental space.
You may feel full faster at meals or notice that cravings for specific foods (especially sugar and processed snacks) begin to quiet. At this stage, you're on the lowest starting dose, so effects are typically subtle.

embody offers doctor-prescribed GLP-1 weight loss treatment - compounded semaglutide and tirzepatide injections - through a 100% online process. Getting started takes a roughly 5-minute health qualifier, after which a medical practitioner reviews your chart (embody says usually within 24 hours, often under 5). Pricing is flat and simple: $69/month for semaglutide and $119/month for tirzepatide, with no insurance required, no hidden fees, and no clinic visits. Medication ships in 1-2 days in temperature-controlled, tracked, insured packaging, and embody is LegitScript-certified and works with US-based 503A compounding pharmacies. On Trustpilot, embody averages 3.8 across 8,398 reviews - an honest, mixed-to-positive record whose recent reviews cluster around two themes: responsive, proactive customer service ('from my very first inquiry I've had excellent communication... customer service updated me every step,' writes one tirzepatide patient) and the no-surprises pricing ('Love the fact that there are no surprises as in costly up front cost'). A 3.7 also means a minority of customers had negative experiences - worth reading both ends of the reviews before deciding, as with any provider.

altRx bills itself as "the #1 most affordable GLP-1 program," and its published prices largely back that up: compounded GLP-1 (semaglutide) from $89/month and GLP-1 + GIP (tirzepatide) from $149/month - flat at every dose, so the price doesn't climb as you titrate up - alongside one of the few genuine brand-name shelves in this space (Ozempic $1,149, Zepbound $1,249, Wegovy $1,579 per month). It's a self-pay telehealth service: you complete a short assessment, a licensed provider (physician, PA, or nurse practitioner) reviews it, and if appropriate a prescription goes to a licensed US pharmacy, with free shipping in about 5-7 days. No insurance is required, Buy Now, Pay Later is available, and you can pause or cancel anytime. Two things to know before the details: shipping is slower than the 1-2 day providers (embody, DirectMeds), and Trustpilot does not currently display an aggregate score on altRx's profile - the individual reviews we quote on this page are real, but there's no independent average to lean on the way there is for rivals like Medvi (4.3 across 14,836) or embody (3.8 across 8,398). One of the real 4-star reviews we surface notes a refill 'yet to be fulfilled with zero reason as to why' - worth factoring in alongside the price advantage.
Read full altRx reviewBy the end of the first month, many patients see 3-5 pounds of weight loss, though this varies widely. The scale is only part of the picture - changes in how clothes fit, energy levels, and your relationship with food are equally important early indicators.
Some patients lose more, some less. Remember: you're still on a low dose.
Weight loss continues at a steady pace as you approach your maintenance dose. The rate may slow compared to months 2-3, which is normal - your body is adjusting.
Patients who combine medication with high protein intake and regular strength training tend to maintain the best momentum. If progress stalls, see our guide on breaking through plateaus.
Every provider's published plans - cheapest first, conditions under each price.
Before starting GLP-1 treatment, it's important to understand a few key things. These medications require a prescription from a licensed clinician and aren't suitable for everyone. Some people may experience side effects, especially during the first few weeks as the body adjusts.
GLP-1s also tend to work best when combined with basic lifestyle habits like balanced nutrition and regular physical activity.
That's why choosing a provider that offers proper medical screening and ongoing follow-up support is essential for both safety and long-term success.
Clinical trials show the most significant results at 68 weeks (about 16 months), with average weight loss of 15% of body weight. Most patients reach their peak results between months 9-15.
After reaching your goal, discuss a maintenance plan with your provider - some patients step down to a lower dose rather than stopping entirely. Read about what happens when you stop.
Don't rely solely on the scale. Track waist measurements, how clothes fit, energy levels, and appetite changes.
Some patients lose inches before they see scale movement. Taking progress photos monthly can also reveal changes that day-to-day weighing misses. Find a provider that includes progress tracking in their program.
