Feedback on combining FGL with a low‑dose KLOW for post‑run recovery

Posted by dita_cycles in Protocols & Stacks - 6 points, 4 comments.

I have been running a simple FGL protocol for the past six weeks – reconstituted 5 mg in 1 ml bacteriostatic water and taking 250 µg (≈0.05 mg/kg) subcutaneously every other day after my evening runs. I noticed slightly better focus during my workouts and a modest reduction in the usual post‑run brain fog, but the muscle soreness remains.

I am considering adding a very low‑dose KLOW component on the days I train hard, mainly the GHK‑Cu 100 µg and BPC‑157 250 µg, keeping KPV and TB‑500 at the standard 2‑3 times per week schedule. My intention is to boost tissue repair without overstimulating the FGFR pathway that FGL already activates.

My questions:

Does anyone have experience with mixing FGL and any of the KLOW ingredients on the same day?
Is the 250 µg BPC‑157 enough to complement FGL’s neuro‑trophic effect, or should I keep it at the usual 500 µg?
Any advice on injection sites or timing to avoid possible irritation when using both peptides together?

I will continue monitoring my blood work and keep the cycle to eight weeks. Any practical insights would be appreciated.

  • grant_climbs: I tried a similar stack for about five weeks while training for a half‑marathon. I kept the FGL dose the same and added GHK‑Cu 100 µg on the hard‑run days, but I lowered BPC‑157 to 250 µg because I was worried about overlapping FGFR stimulation. For me the extra GHK‑Cu seemed to reduce joint tightness a little, and the lower BPC‑157 dose gave no extra soreness; the 500 µg dose felt no different but increased injection volume which made the site a bit more irritated. I injected FGL into the abdo
  • erin_rows: Sounds about right – I also split sites and left a couple of hours between them. For me the 100 µg GHK‑Cu made the knees feel a touch looser, but dropping BPC‑157 didn’t seem to change anything beyond the extra volume. Maybe stick with the lower BPC‑157 if injection comfort is a priority.
  • dita_cycles: Thanks for the details, Erin. I’ll keep the BPC‑157 at 250 µg then and space the injections by a few hours as you do. I’ll also watch the knee feel – if the GHK‑Cu gives that slight looseness I might keep it on hard‑run days only. Do you rotate the sub‑Q spot for the GHK‑Cu or stay in the same area?
  • dita_cycles: Thanks for the details, especially the note about thigh injections. I’ve been using abdomen for FGL as well, so I’ll try moving GHK‑Cu and BPC‑157 to the thigh and keep a two‑hour gap. Your experience with 250 µg BPC‑157 not adding soreness lines up with my feeling that 500 µg might be overkill for neuro‑trophic support, so I’ll stay at 250 µg for now. Do you notice any change in sleep quality when you add the GHK‑Cu on hard‑run days?
