GHS vs GLP-1 for fat loss — settle this
30 posts
Seeing a lot of 'GHS for recomp' posts and I want to push back because I've done both back to back and the comparison isn't close.
16 weeks GHS (CJC+Ipa 200/100 3x daily, 8wk on/4wk off, then 8 more on): lost 4.2 lb, waist -0.5". 16 weeks tirze (2.5 → 7.5mg): lost 22 lb, waist -3".
Same training, same nutrition intent (didn't hit protein as clean on GHS because appetite was high).
For fat loss as a primary outcome, GLP-1 class is simply a different order of magnitude. GHS as a fat loss tool is marginal at best.
The GHS case is sleep, subjective recovery, and probably some lean mass preservation during a GLP-1 cut. Running them together is where the actual recomp case lives — not GHS alone.

This is the take more people need. GHS is framed as a body comp tool by marketing and it's really not — it's a recovery/sleep tool that has small body comp effects as a side benefit.

The protein-during-cut question is actually where GHS earns its keep. On tirze alone with appetite down you risk losing LBM. Stack GHS and you're more likely to preserve. That's the combined recomp play.

Agreed. If someone asks me 'should I run GHS or tirze for weight loss' the answer is always tirze. GHS comes in for the parallel concerns — sleep, LBM preservation during the tirze cut.

Mechanism-wise this is exactly right. GLP-1 creates energy deficit via appetite suppression. GHS modulates what the body does in that deficit — preferentially burning fat and preserving muscle via IGF-mediated synthesis.

Paired DEXA: tirze alone (last year): -22lb, -3.8 LBM. Tirze + CJC/Ipa (this year): -19lb, -1.4 LBM. The LBM delta is significant. GHS is doing work specifically on composition.

@dexa_devotee this is the data I was looking for. 2.4 lb LBM swing on a 20lb cut is the difference between 'cut' and 'recomp.'

Before everyone races to stack — GHS adds injection burden and cost. For someone who isn't lifting hard and isn't getting adequate protein, GHS isn't going to magically preserve LBM. Training and protein intake are the primary LBM drivers. GHS is a secondary lever.

Correct framing: GHS is an amplifier, not a driver. If the substrate (protein) and the stimulus (training) aren't there, GHS doesn't rescue you.

Point of this post wasn't to diss GHS. It was to set accurate expectations. Running CJC+Ipa right now with tirze and it's the best protocol I've done. Just don't start GHS expecting fat loss.
