CJC-1295, ipamorelin, tesamorelin, GHRP-2, GHRP-6, PEG-MGF and MOTS-c: what each is and what the research shows.
CJC-1295: two molecules under one name, what each does, and what was actually measured
What CJC-1295 does, and why the CJC-1295 peptide is really two molecules: the long-acting DAC form studied in small human trials and the no-DAC form (mod GRF 1-29) with no published human studies. Half-life, GH and IGF-1 results, downsides, the ipamorelin stack, cost context and what users report.
GHRP-2 (pralmorelin): what it is, how people use it, and what the evidence shows
GHRP-2 (pralmorelin) is a synthetic hexapeptide and growth hormone secretagogue that binds the ghrelin receptor, used for physique, recovery and appetite. What it is, how it works, what its short-term human evidence shows, its side effects, and how it compares with GHRP-6 and ipamorelin.
GHRP-6: what it is, how people use it, and what the evidence shows
GHRP-6 is a synthetic hexapeptide growth hormone secretagogue and ghrelin-receptor agonist, similar to GHRP-2 but known for pronounced appetite stimulation, used for muscle, weight gain and recovery. What it is, how it works, what its thin, short-term evidence shows, its side effects, and how it compares with GHRP-2 and ipamorelin.
Ipamorelin peptide: what it is, what it does, and where the claims outrun the evidence
What the ipamorelin peptide is and what it actually does: a short growth hormone pulse in human volunteers, the claimed benefits next to what studies measured, how it compares with CJC-1295, tesamorelin and sermorelin, side effects, cost context, and what users say about the CJC-1295 stack.
The MOTS-c peptide: what the 'exercise in a vial' actually does in mice and in people
What the MOTS-c peptide (MOTS c peptide) is, what it does, and what it is used for: the mouse and early human evidence behind the 'exercise in a vial' pitch, metabolic vs muscle claims, how long studies dosed it, side effects, cost context and what the community reports.
PEG-MGF: what it is, how people use it, and what the evidence actually shows
PEG-MGF is a pegylated form of mechano growth factor, a splice variant of IGF-1 sold as a research peptide for muscle repair and growth. What it is, how it is thought to work, what its mostly preclinical evidence shows (including a controlled study that found no effect on muscle cells), and what is and is not known about its safety.
Tesamorelin: what it is, what it does, and what the evidence supports
A plain-spoken overview of tesamorelin, the growth hormone-releasing hormone analog sold as Egrifta: what the FDA label covers, what its trials measured, its side effects and who should not take it, how it compares with CJC-1295 and ipamorelin, what it costs, and why fat-loss and physique communities use it off-label.
