Imagine your muscle system as a handmade Patek Philippe watch. Not a flashy accessory, but a mechanical masterpiece built from hundreds of micro-engineered components, each one tuned to transfer energy, rhythm, and precision. When a watch like this is young and perfectly calibrated, the movement runs smoothly, the second hand glides, the chronograph responds instantly, and every gear communicates with the next with almost zero friction. But as time passes, even the finest watch quietly drifts out of tune. Lubrication thickens. Gears lose polish. The escapement rhythm softens. Nothing breaks, but the internal conversation weakens. The watch still tells time, just not with the effortless elegance it once had. Aging muscle behaves the same way. Inside the cell, one of the signals that keeps everything responsive is PGE2, a messenger molecule that tells mitochondria how to renew themselves, activates stem cells for repair, and helps the neuromuscular system stay sharp. The enzyme that breaks PGE2 down is 15-PGDH. In youth, it functions normally. With age, it becomes overactive and wipes away PGE2 too quickly, the same way overcleaning a watch strips away its essential lubrication. The result is muscle tissue that feels slower, tighter, less coordinated, and less responsive to training not because the parts are missing, but because they’re no longer communicating clearly. A new compound being studied called MF-300 gently inhibits 15-PGDH, allowing PGE2 to remain active long enough to deliver its full message. Nothing is forced. Nothing is artificially overstimulated. Instead, the internal calibration is restored. Once PGE2 is back in the picture, it activates a receptor called EP4, which functions like the watch’s regulation lever guiding energy release, timing, and resilience. EP4 then activates PKA, a master switch inside the cell that initiates mitochondrial maintenance, improves calcium handling, stabilizes neuromuscular communication, and wakes up satellite cells for repair. Beginners can think of this like relubricating the watch’s movement. Experts will recognize it as the cascade of cAMP, CREB signaling, PGC-1α activation, and downstream transcriptional changes that rebuild energy systems and restore functional capacity.

June - August 2024 I was living in Portugal, lovely sun in the morning. Morning steps, cold plunge and sauna everyday. Super cool room on a night. I was on TRT and GH and RHR got down to about 48bpm. This year June 2025 I started reta, still on gh, trt......and I only went up to 3mg a week. My RHR has gone up to almost 70. Even when I stopped in for 4 weeks it didn't really move lower. Now I'm not sure why it's staying spiked, I was considering adding in a low dose Nebivolol but I know I shouldn't need to take something just to counteract that. We all know RETA increases RHR in a lot. But what else can I look at to see if anything else is causing this? Thanks

Whose used this? I have some, running 200mg a day, deffo sweat a bit more during cardio, if I combine it with SLU I get a noticeable increase in body temp. Not sure on dosing as see people saying once per day, multiple times etc. Anyone got experiences and share what they have found?

I am one of those people who on day one when I used Metashred (BAM/SLU combo) it sent me to the ER. Tried again a week later and although I was able to stay away from the ER it wasn't a pretty couple of hours. I decided instead to split up the two (SLU on training days and BAM on rest days). Been using SLU for a while at various dosages with no issues. For BAM, the capsules I have are 15mg. Took my first dosage yesterday on my rest day without issue. Is there a dosage I should be working up to?

I was wondering if you have archives of your articles? I just read this article from the SR about VIP and I cannot tell if it is good or bad (after already placing an order). So looking for more clarity about using it.
