PCR Broad Spectrum Plant Oil Testimonials*

Importance of Obtaining PCR Plant Oil from an Expert

"The testimonials are simply amazing. We know that it is not just the product but the person behind them, [Susan Merenstein], that is helping your patients get healthier."

- Raj Gupta, Ph.D. Chief Scientific Officer at Folium Biosciences

LabNaturals PCR

"You have to be careful when buying these oils because you don’t know for sure what you’re getting. So, I buy mine from a reputable pharmacist in Pittsburgh. I’m taking 500 mg 2 ml a day. Just increased by 0.5 ml. I think I paid $80.00 for this bottle. Now Susan Merenstein has higher milligrams which of course cost more! She will even ship to your home! I get my compounded thyroid and hydrocortisone from her. They are wonderful there!!!"

- J.J.

“Really, really helped! Excellent! Immediate relief from joint and muscle pain.”

– R.A.

“I use the balm. It got rid of my neuropathy. I was able to get off of the oxycodone, Neurontin, and other pain relievers. A little dab goes a looong way. My oncologist recommends it to his patients now because of my success with it.”

– N.K.

LabNaturals PCR for Tremors

"When I was home I was able to convince mum to try a regimen of LabNaturals PCR caps for her tremors. Shout out to Susan at Murray Avenue Apothecary for the great advice and care. Above and beyond. After moving up to 30 mg a day her hands are calm. Unbelievable. Couldn't recommend LabNaturals PCR enough..."

- E.T.

Parkinson's Disease

“I just started using the LabNaturals PCR Oil per Susan’s recommendation for my Parkinson’s. I have already experienced a reduction in my rigidity, tremors, and pain and I am feeling better overall. I am truly hopeful that I will continue to improve.

In addition, I believe the Magnesium oil is also helping to relieve my aches and pains.”

- D.D.

LabNaturals PCR for Surgery

“A client who us using LabNaturals PCR Oil in place of opioids (he is an ex-addict) for knee surgery. His girlfriend stopped in to buy another bottle and said he is doing great! He is a couple days post-surgery and the LabNaturals PCR is taking care of his pain excellently! We had him taper up to 100mg per day in the week prior to surgery and having him continue at 100mg per day for a few days then taper slowly back down.”

- Pharm D Clinical Observation


"So I just wanted you to know that ever since taking the PCR about a month ago, I have felt a MILLION times better. I seriously feel like a whole different person – my anxiety and depression has almost disappeared. Even my family has noticed a difference in my personality. I’m more optimistic and upbeat. It feels so much better to be back to my normal self again. It’s amazing what a natural supplement can do!"

– K.S.

“I’ve been recommending LabNaturals PCR a lot lately. Hope folks are coming to [Murray Avenue Apothecary] (The only place we mention…) We witnessed the calming effects in a dog that hates getting her nails done. Literally usually a 3-person job. We were shocked. The owner works in LA and has used it for calming a stray dog she took in as well. I am going to try it for my own dog’s anxiety. Thank You!”

– Dr. B. Veterinarian

Postherpetic Neuralgia

"I’ve been suffering from Postherpetic Neuralgia related to shingles since 2009. From 20011-2017 I took 300mg of gabapentin at night to help ease the pain. Nothing took the pain away completely but I lived with it knowing full well that it could be much worse. I happened upon the Apothecary on my way back from the bank and stopped in at my mother’s urging. Always listen to your mom!!! Susan and her staff were so knowledgeable about the product and I immediately felt comfortable buying from them rather than online. Within 24 hours my pain had subsided. Within 48 hours it was completely gone. Six-months later and I’m still pain free and so happy to be done with expensive drugs that have unwanted side effects. Added bonus, with LabNaturals PCR oil, I have noticed deep sleep and my body sure does need that.”

- Renee Alvarez


(Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections)

“Several of my son’s specialists had suggested he try LabNaturals PCR oil during the past year to see if it would help at all, although they had little to no knowledge of a company to turn to or proper dosage for my son. We have been long time clients of Murray Avenue Apothecary and turn to Susan Merenstein for her advice and expertise. Following a consultation with Susan on 6/1/17, we were thrilled to have the proper guidance and access to the superior product that she recommended LabNaturals PCR. Although, Susan suggested .25 ml 2x/day for my son, I was aware of several cases of children with similar diagnoses as my son for whom LabNaturals PCR oil had a stimulating effect and could not tolerate the oil. With that knowledge, I opted to start with a very small dose (.1ml) to explore the effect of LabNaturals PCR on my son. Within 30 minutes of starting the oil, my son reported an overall calm feeling and the rages and emotional lability that had occurred just prior to that first dose quickly subsided.

Unfortunately, 5-6 hours later, he began feeling out of control once again, however, not as severely as before. About an hour before bedtime that evening, I doubled the dosage to .2 ml. Once again, he felt calm within 15-20 minutes and slept soundly that evening. He slept a total 9 hours—an hour longer than usual—and felt more refreshed in the morning than he had in a long time.

Beginning the following day, he began the recommended .25 ml every 12 hours. He has been on this dosage for the past 19 days with extremely positive results. Since starting the product, my son’s anxiety has decreased drastically, his raging has stopped, brain fog is gone, and emotions are regulated. He is happier, his joint pain has disappeared, and his academic skills have improved. Although OCD is still elevated, it is at a slightly lower level than before. My husband and I are extremely grateful that we have access to LabNaturals PCR products and plan to use them for my son for the long term. The change in my son in such a short period of time has been quite remarkable. Thank you, Susan, for your expertise, and thank you for your life-changing product.”

- B.M.

“An 11-year-old boy who was bedridden with Lyme and PANS began getting out of bed after two days on the oil, and within the first month made a dramatic recovery.”


Arthritis and Pain

“I've waited til today to post. I've been taking 1/2 of the recommended dosage for my arthritis and severe knee pain (I need 2 knee replacements) since Tuesday. I took 1/2 the recommended dose this AM and will take the other half tonight. I've been feeling positive results from day 1, but today was the best. I have no sharp knee pains but do feel the pressure of bone on bone in my knees when I walk. I could cry!! What a relief!! A side effect is that I feel calmer and less anxious!! Thank you, Susan, for providing this to the people of Pittsburgh!!”

– A.G.

Crohn’s Disease

“Had the typical start to Crohn’s flare up. Joint pain- gut pain- lots of inflammation. After about three or four oral small doses of LabNaturals PCR, all symptoms have disappeared. I would highly recommend this product for people who need help with auto immune inflammation.”

– B.M. Optician


“When diagnosed with a spot of melanoma for the 4th time, I felt it was time to be more proactive about my care. After contacting Susan, we settled on LabNaturals PCR to help with the current cancer and my anxiety. The effect on my mood was almost immediate. After 4 weeks of taking the oil, I went in for surgery on the affected area and was told it looked more like a suspicious mole than cancer. In addition, my scar from surgery is almost undetectable. Thank you to everyone at the Murray Ave Pharmacy. You are literally saving lives.” – JS

“I spoke to a pharmacist who advised me on the strength and appropriate dose. I felt I was properly evaluated for treatment before I purchased the LabNaturals PCR.”

GI Health

“I felt I was out of hope. Then I came to the Pharmacy. My GI doctor wanted me to go on an immune suppression drug. I wasn’t ready to do that. Gradually over the first few weeks my symptoms – which resembled irritable bowel, began to get less and less, and more normal stools have occurred.”

“About 5-7 days after the first does the painful cramping and evacuation of stood improved. I felt better. I had less pain and cramping than I had experienced on and off all day.”


“For 25 years I’ve taken gabapentin for headaches related to brain surgery and then additionally for shingles related pain since 2007. I immediately stopped gabapentin once I started LabNaturals PCR oil and I haven’t gone back. Also, gabapentin only dulled postherpetic neuralgia pain. LabNaturals PCR oil has practically eliminated it.”

“Within 24 hours I received complete relief from shingles related pHN (postherpetic neuralgia) and I have been mostly pain free since June 2017. An added benefit is that I also get amazing sleep now.


“I have been getting the best sleep of my life. Each night I fall into a deep sleep until my alarm goes off.”

“I feel like my overall wellbeing has improved. Maybe it’s because I’m getting truly restful sleep and my body is no longer fighting the pain.”

“I feel very calm on this and sleep is better, longer and more restful.”

“No more insomnia!”
