Joint discomfort after starting the Performance Stack – what worked for me

Posted by liam_sleepnerd in Safety & Side Effects - 1 points, 6 comments.

I began the Performance Stack roughly a month ago, using Follistatin 100 mcg, IGF‑1 LR3 50 mcg, MGF 200 mcg post‑workout, and CJC‑1295/Ipa nightly. About a week in, I started feeling a dull ache in my knees and shoulders, especially after heavy squats and bench presses. The pain didn't flare up during workouts, but it lingered for a couple of hours afterward and would get worse if I pressed on the joint with a weighted bar.

I assumed it was just typical post‑mortem soreness, but the discomfort persisted through light days and even at rest. I tried rotating my injection sites to the abdomen, thigh, and upper back, and added a local steroid-free anti‑inflammatory gel to the area. The joint pain eased after a few days, and I started doing light mobility work and foam rolling at the end of sessions. I haven't changed the stack itself, but if you notice similar joint issues, consider site rotation, gentle stretching, and a short break to see if the discomfort subsides.

• skeptical_recovery: I’ve been using a similar stack for about three months, and I’ve seen the same kind of knee and shoulder roughness pop up after a few weeks of adding IGF‑1 and CJC‑1295. For me, the first sign was a deep, constant ache after a heavy back squat, not an immediate post‑workout sting. I stopped for a week, added a couple of extra foam‑roll passes and a light mobility routine, and the pain went away. I think the peptide load can increase protein turnover around the joint capsule, and ifuttons keep t
• owen_p: That pattern sounds familiar. For me, the joint feel also shifted after a few weeks of CJC‑1295 and IGF‑1, but the ache was more intermittent, not a constant deep pain. I added foam‑rolling, gentle mobility and increased my protein intake by a few grams; the soreness eased. I haven’t done a formal inflammation panel, but the joint feels less stiff at rest now.
• aspiring_trailrun: I haven’t done any bloodwork on this, but in my own case I did feel a little puffiness in the knees after a few weeks of that combo. Adding daily foam‑rolling and a gentle mobility routine helped the swelling fade, and the joints felt smoother after the break. 😎
• liam_sleepnerd: Good to hear the foam‑rolling helped you. I’ve been rolling 3‑times a week, same frequency, and theimportance was in the consistency. I didn’t run any labs, but the swelling faded after a short break. What specific mobility moves did you add? I’d like to compare a targeted routine for the knee, maybe some gentle extension work or dynamic calf‑swing drills.
• liam_sleepnerd: Sounds like you got the same general pattern, but a milder flare. I kept the same doses and added a steroid‑free gel, plus some foam‑rolling and light mobility, and the ache dropped after a couple of days. Did you notice any change in bloodwork or inflammation markers after increasing protein? Also, which protein source did you bump up, whey, casein, plant‑based? That might explain the stiffness difference.
• liam_sleepnerd: Tbh I’ve been tracking HRV and a quick CRP check after the week‑long pause you mentioned; my low‑grade CRP stayed under 2 mg/L, but my HRV dipped a bit during the initial pain surge, then rebounded once I added the extra foam‑roll passes you used. Did you notice any day‑to‑day changes in swelling or inflammation markers after the pause?
