Review: Practically Miraculous - Great product. Info for FIBROID sufferers below. ---- TMI Warning, graphic, explicit info follows. ---- I bought this in hopes of reducing extremely heavy menstrual bleeding and clots. I had bled non-stop for months, with only occasional non-bleeding days, and clots often the size of an extra large egg. The anemia was getting to me and I was concerned I wouldn't be able to live through it if it continued. In desperation I started using these EGCG pills in conjunction with fibroid reduction homeopathy drops and Chi's Myomin, plus adding grape seed oil to my greens at meals. I also started doing however much I could do (not much) of HIIT exercise once every three days. I'd used this protocol for only 2 weeks before my cycle. This cycle I've had less than half the bleeding, and the clots are down to about 1/3 the size and frequency. Honestly I can't say which of the items is doing the trick, or if it's the synergy between them, but it's working and that's all that matters. Will definitely purchase again. -- UPDATE -- After amazing success doing this for a month, I had a bad detox overload (body ache, migraines, fever, in bed two days). I'm sad I didn't prepare for the heavy load this kind of detox puts on the body, I know about Herxheimer reactions and should have seen it coming. I started taking support for the detox pathways (molybdenum, b1-b6, milk thistle, NAC, parsley, fresh organic lemon juice in water, l-glutamine and l-lysine) and it eliminated the detox side effects. I'm also taking a break from the detox to let my body recover before I do my next round. Next cycle I'll be sure to detox the fibroids out with better detox pathway care.
Review: I feel this is the best Green Tea Extract on the market because there is NO advancement of my Amyloid disease after 3 months. - I was diagnosed with Wild-Type Tranthyretin Amyloid. No Medicines currently available. A GERMAN study using Green Tea had a very positive result. I researched and found RELENTLESS IMPROVEMENT had the supplement with the EGCG I required with low caffeine. I currently take two capsules with a Natural Vitamin C (no stomach problems) at 4:00AM on an empty stomach for max absorption. I had a question on the amount of black pepper berry extract in each capsule. I sent the question to the company and got an immediate reply from Kim Bryant that the amount was only 1mg. I feel this is the best Green Tea Extract on the market because: it is decaffeinated, has the maximum amount of EGCG, solvent free water extraction process, and does not bother an empty stomach (can go right back to sleep after taking @ 4:00AM).

### ⭐⭐⭐⭐⭐ Excellent Product
*by R***R on October 20, 2021*

I just purchased my second bottle and will continue to purchase from this company. I've had noticeable improvements from using it, in both my health and my skin from the polyphenols and other beneficial constituents that are in quality green tea extracts. The main reason I purchased from Relentless Improvement is the lack of fillers which many other brands use. I've purchased other supplements from this company as well, for several years now, and whenever I need any new supplements I always check them first to see if they carry it. All of their products I've purchased have been high quality and worth every penny.
