Customer photo review of Complex ProMAX 6 Bottles

Cassi W.Verified

These drops combined with the very strict 500 calorie diet = successful, fast weight loss. I have used their regular complex diet drops in the past, but the last couple of times, I experienced a few weight loss plateaus. I decided to try the Complex ProMAX drops this time - they work just as well and so far, I haven’t experienced a plateau :)

Upon recommendation of a co-worker I tried your amazing product. This is the first time I have dieted in 69 yrs! With Covid I had gained an extra 10-15 lbs. I am three wks in and have lost 8 lbs. Cut out all carbs. Great product partnered with smart menu choices, and exactly the slow and steady results I was seeking. Thank you!

I have been successfully using the Complex Diet Drops for a few years now so I thought I would try the B Complex. I absolutely love it. I have noticed a difference in my energy level and the taste is great. Will continue to use!

I just started with the drops! So not much to say about the drops now. But I do have high hopes. I have started out very slow. But my appetite has decreased, Somewhat with these drops. And I’m pretty excited about that. I will start the diet protocol this week.

I turned to BioSource’s Complex drops after regaining some weight I had lost with HcG. With that product no longer on the market, I was at a total loss, as I find it basically impossible to drop weight with any other diet. I have had better success with Complex ProMAX than the basic complex, but as the description says, it’s best for “experienced dieters” and I’m definitely that, having yoyo-ed my entire adult life. It’s a great aide, curbing hunger and balancing blood sugar levels. Whenever p...

Eileen W.Verified

Love the pro-max! I’m 69 yrs old and just didn’t like how I looked. On my First round of the Pro-MAX I lost 30 pounds in the six weeks. I followed the diet rules without cheating, except the water intake and coffee creamer. I stopped eating at 7 pm and went to 11 am the next day without eating. The second round I lost 8 lbs but did cheat more. I have went off the drops for two weeks and maintained my weight loss. I will start my third round tomorrow. I will hopefully follow the rules without che...

Tamela G.Verified

This product is a miracle in a bottle. I have high blood pressure and I was worried how my body would react to the diet. I had to a few twerk here and there but I have lost a lot of weight. I didn't take any photos because I didn't know whether the diet would work or not. I will keep using this product. I'm not sharing for the discount either because I have really benefited from this product.

Working just as promised! Due to an injury I am unable to exercise very much. I tried many diets some worked for a while, most required physical effort. This was the first weight loss program, incentivizing me to follow the calorie counting, because I could see the results almost immediately!

This has helped me not to be hungry between meals. Sometimes I don’t even feel hungry for meal time. Helps a lot in the evening by controlling my snacking. I lost a couple lbs a week.

Great product to move the mountains, so to speak. As I once heard a saying like this, (not exact words, but same idea) "It doesn't make you go more often; you just move more when you go." ~ jeff

I've been taking Complex Promax & Complex Diet Drops for a few months now. I think they both help with controlling my appetite. I would definitely purchase both again when I run out.

The drops work so well to control hunger, cravings, manages the desire to eat too much. No adverse side effects. Very well made formulas in both the diet drops and the complex.

Karen G.Verified

I was on a similar diet a few years ago which was very expensive. This time, I already had the diet (which is basically the same as the little booklet you sent!), but I needed the drops to help keep my appetite under control. I am so happy to say that this formula worked like a dream! I lost almost 25 lbs in a little over a month, for a fraction of the price I paid with the other diet. It really works! I wasn’t hungry at all, and it was easy to stick to the plan. I wholeheartedly recommend this ...

Like the drops. We have used them off and on for years. I was supposed to get the cookbook with my order and it wasn’t included. Also the bottles aren’t in boxes anymore. The four glass bottles were just in a lightly padded envelope. I am surprised they didn’t break. Felt cheap instead of professional. How can I get the cookbook? I am eager for ideas when in the 21 or 40 day protocol. Thank you! Diane from Utah

Complex Buy 2 Get 2 Free I was a little skeptical of this product actual working. However, this has been a great jumpstart to my weight loss journey and seeing the weight fall off has been even more motivating. I have only been a week and half in and I am already down 10 pounds down with the 500 calorie plan. I know everyone�s body is different and I feel that if you follow there regimen you have nothing to lose but the weight.
