I’ve been using the CJC-1295 /Ipamorelin blend and IGF-1
I’ve been using the CJC-1295 + Ipamorelin blend, and honestly, the difference in how I feel alone is worth it better sleep, improved recovery, and a noticeable boost in overall wellbeing.
But when I added IGF-1 LR3, that’s when things really stepped up. It went from just feeling better to actually seeing physical changes happen faster.As a woman in her 50s and perimenopausal this stack has been particularly impactful. It’s helped support muscle preservation (which is so important during hormonal changes), while also improving my energy levels and recovery time between workouts.
Over time, I’ve noticed:
Increased lean muscle development
Better muscle fullness and tone
Gradual fat reduction
A tighter, more athletic look overall
Improved sleep quality, likely from the growth hormone support
This combination doesn’t feel extreme or overwhelming — it feels supportive, especially for where my body is at now. It’s been a solid addition to my routine and has helped me feel stronger, leaner, and more confident.
Highly recommend for anyone 40+ looking to support their body through this phase while still making real progress.
