I picked up a two month supply and have just run out. Already I can see my chest starting to swell and soften. The 4 pack system not only works, it works well and quickly. I have just placed my second order, this time I'm going for the liquid extract 4 pack. I look forward to seeing continued amazing results.

Been using these products for about 4 months. Although the physical effects are so much more apparent except to me the emotional effects are amazing. I highly recommend this product.

4 pack review
Posted May 15th 2020 by Carly Ellen

In have been taking these supplements for about 6 months. I have noticed several good changes. Breasts have grown about 1 full sizem from 42 b before starting, to 42 c now. I comfortably dill out blouses, tee shitrs and dresses. The changes take some time, it isn't overnight. My body hair is noticeable thinner and less course, and grows much slower then before using the shops. Please keep in mind that i am much older, making the transition late inlife, so body changes will not be as dramatic for me as for much younger girls. Internally, I experience feelings with much more ease and intensity. I am surprised to find myself with tears so often. Don't expect miracle changes, but stick with it for awhile and you will see a difference. Carly

Truly Amazing

4 Pack
Posted Mar 24th 2020 by Jennifer Walker

I started on this course just 6 weeks ago and while the results aren't spectacular as some other posters have claimed I now see slow but steady breast growth, a slightly firmer and rounder butt, and body hair very slowly staring to get finer. Please as an honest reviewer take the claims of changes within a week or two as exaggerated and understand that there in no product that can transform you overnight so to speak unless you are willing to pay $1000's and have surgery. What I can say is that for me progress is slow but steady just as I thought it would be. Yes it would have been faster with Estradiol and Spirolactone but as those proven drugs are prescription only and cost a fortune if you are willing like me to take probably 12-18 months to reach your goal then this 4 pack treatment will get you there. Love and good wishes to all. Jenny.

Love it, it really works.
Posted Mar 14th 2020 by Donna Seenath

This product is amazing I’ve always wanted to be a female so I thought I would try a more natural way at first I didn’t think it was working and after a few weeks I’ve noticed changes slow will definitely keep using this product forever. In public i still like to dress as a male but I definitely can start to feel the female side of me and love it. Definitely not a waste of money like I thought it would be

Been loving your products

Although the extracts are more potent these have helped my mood and allowed my breasts to grow and hips get wider. Great products and I do recommend all of them. From the capsule form to the liquid extracts.

The 4 Pack is Great!

Effective! Best products on the market! Loving the growth/transition!

Posted Jul 18th 2019 by Darcie

I started the 4 pack and have already noticed changes in my body. A little more curve and breasts getting a little larger. Also has a calming effect for me plus no jitters. Had a bad experience with another brand. Love these supplements and plan on taking them until I reach my desired goal. I definitely recommend these supplements to anyone that is planning to transition the non medical way.

Posted Jun 17th 2019 by hayden c

Amazing products and been a loyal customer for three years Just wish they came in bigger bottles (oils) but bye far the best non medical (safe) way to transform. Sent to Australia no problems & I cant get enough of the products and if you buy enough they sometimes pack a small gift (an extra) for their most loyal customers (I think im due for a freebie soon lol)

Works pretty well

Been taking these pills for 3 months now and finally starting to notice some small changes. Some mood swings and some breast growth! Can't wait to see how much further I can progress

Posted Sep 9th 2018 by Carrie

I love the 4 pack! I have only been using this product for a few months and I have noticed a few changes so far but I can’t wait to see what more changes I see in the future. I would definitely recommend this product to anyone seeking to transition.

Getting Great Results
Posted Aug 30th 2018 by Doni

I started taking HRT Pills Dec 2017 I started with a different brand of pills until May when I found out about Transformation Labs. I started out 2 months with the 3 pack MTF Pills. Started to see results, with less body hair, Softer Skin, Different Emotions, and chest development. I have even seen a little facial differences. I now have been on the 4 pack for 2 months now and am seeing gradual changes every week. Cant wait to see how I progress along. I love these pills. I take 3 pills a day with lots of water. Thank You Transformation Labs.

I am a woman with really high testosterone levels. I spent a fortune on prescriptions from my endocrinologist. These pills work so much better than the medicine I was taking, at a fraction of the cost. I actually feel “normal” again. No more sluggishness and aggression. Thank you for this product!

It REALLY works!

Love the 4 pack M2f transitioning love the feeling of my body changing and how I feel normal the price isn’t too bad but I only wish you got a full months supply with each bottle 50 pills in a bottle is not enough in a month if you take them 2 times a day out some of the bottles recommend 4 times I would just stay at. 1 each in morning and night Other wise love the product

best for MTF
