Interested in hearing experiences or insight into somalong/somapacitan
It also seems to have a few other names, so I'll post some studies
Seen K4L has some of this, but I can't really find many anecdotal reports on the compound. It seems like its a GH analogue, rather than actual GH. I was debating maybe stacking a low dose with exogenous GH but wanted to get some opinions/insight into the compounds if possible. It seems to be relatively new which is why I'm slightly hesistant, but it could be a good discussion to have for future reference
"Somapacitan is a new long-acting human GH (hGH) analogue that is administered once a week by subcutaneous injection. It was first approved by the U.S. Food and Drug Administration (FDA) as GH replacement therapy for adults with GHD, becoming the first hGH therapy for AGHD administered by once-weekly injection, compared with other approved hGH therapies for AGHD administered by daily injection. This article reviews the pharmacokinetic, clinical and safety data that led to the approval of somapacitan as the first long-acting GH therapy for adults with GHD."
"Context: Somatrogon is a long-acting recombinant human growth hormone (rhGH) in development for once-weekly treatment of children with growth hormone deficiency (GHD).
Objective: We aimed to compare the efficacy and safety of once-weekly somatrogon with once-daily somatropin in prepubertal children with GHD.
Methods: In this 12-month, open-label, randomized, active-controlled, parallel-group, phase 3 study, participants were randomized 1:1 to receive once-weekly somatrogon (0.66 mg/kg/week) or once-daily somatropin (0.24 mg/kg/week) for 12 months. A total of 228 prepubertal children (boys aged 3-11 years, girls aged 3-10 years) with GHD, impaired height and height velocity (HV), and no prior rhGH treatment were randomized and 224 received ≥1 dose of study treatment (somatrogon: 109; somatropin: 115). The primary endpoint was annualized HV at month 12.
Results: HV at month 12 was 10.10 cm/year for somatrogon-treated subjects and 9.78 cm/year for somatropin-treated subjects, with a treatment difference (somatrogon-somatropin) of 0.33 (95% CI: -0.24, 0.89). The lower bound of the 2-sided 95% CI was higher than the prespecified noninferiority margin (-1.8 cm/year), demonstrating noninferiority of once-weekly somatrogon vs daily somatropin. HV at month 6 and change in height standard deviation score at months 6 and 12 were similar between both treatment groups. Both treatments were well tolerated, with a similar percentage of subjects experiencing mild to moderate treatment-emergent adverse events in both groups (somatrogon: 78.9%, somatropin: 79.1%).
Conclusion: The efficacy of once-weekly somatrogon was noninferior to once-daily somatropin, with similar safety and tolerability profiles."

Somapacitan: a long-acting growth hormone derivative for treatment of growth hormone deficiency - PubMed
Growth hormone deficiency (GHD) is characterized by inadequate HG production from the anterior pituitary gland. Adult patients with GHD have increased fat mass, an abnormal lipid profile, decreased lean body mass and bone mineral density, decreased muscle strength and exercise endurance, and a...
