Semaglutide

8 sourced research updates tagged Semaglutide, newest first — what changed, what the evidence shows and what it means for how people run a protocol.

Body composition

How much protein to eat while losing weight on a GLP-1

During weight loss on a GLP-1, a common practical target is roughly 1.2–1.6 g of protein per kilogram of body weight per day — higher than general adult requirements, because a substantial share of…

Interactions

Taking metformin and a GLP-1 together: what actually changes

Metformin and GLP-1 receptor agonists are routinely prescribed together and there is no pharmacokinetic interaction requiring a dose change between them.

GLP-1 & metabolic

The first small-molecule GLP-1 pill is approved — what Foundayo changes

In April 2026 the FDA approved orforglipron (brand name Foundayo), the first small-molecule oral GLP-1 receptor agonist for chronic weight management.

Body composition

The muscle problem with GLP-1s finally has trial data behind it

Up to 40% of the weight lost on GLP-1 therapy can come from lean mass, not fat. Two Phase 2 programs now show that this is partly fixable with drugs: the BELIEVE trial combined semaglutide with…

Practical dosing

Is there a best time of day to take a weekly GLP-1?

Once-weekly semaglutide and tirzepatide can be injected at any time of day, with or without food, because their half-lives are measured in days rather than hours.

Practical dosing

A simple injection-site rotation schedule for weekly injections

Approved weekly GLP-1 injections go subcutaneously into the abdomen, thigh or upper arm, and absorption is equivalent across those sites.

Storage & handling

How long a reconstituted peptide really lasts in the fridge

Two separate clocks run on a reconstituted peptide vial kept in the fridge: chemical stability of the peptide in solution, and microbiological safety of a container you puncture repeatedly.

Practical dosing

You missed your weekly GLP-1 dose — what the label actually says

For once-weekly semaglutide, the label says take the missed dose within 5 days of the scheduled day; past that, skip it and resume your normal schedule.
