*I purchased LGI EPI-10 with my own money, and was not sponsored to complete this cycle*


I recently completed a cycle of EPI-10, which I planned on doing for 5 weeks, but was cut short to 4 weeks; and I will explain later.
*This cycle only contained LGI EPI-10 along support supplements and PCT supplements*

My history with PH's:
It has been about five years since I completed a PH cycle. My last cycle was Purus Labs Halavor, and I did not use proper PCT. Prior to that I completed a Tren cycle, again without proper PCT. After doing my homework and realizing that I was doing my cycles incorrectly, I decided to take a long break and do some research before completing another PH cycle. Therefore, for the last five + years, I have been running a lot of natty test boosters, reading forums, and researching. I have gained a lot of lean muscle from the test boosters; however, after years of test boosters I was starting to not see gains as much anymore. I decided that it was time to at least try a PH cycle (correctly). Therefore, after a lot of research I decided to give EPI a try. LGI has a good reputation in the supplement industry, and I thought that LGI would be great place to start.

My supplements during this cycle:
Fish oil (Store brand)-on cycle and PCT
Taurine (Prime Nutrition) - for blood pressure –on cycle and PCT
Cycle Support (AI Nutrition) –Two scoops a day- Preload, on cycle, and PCT
Glutamine (Body Tech)-on cycle and PCT
Nolvadex (Tamoxifen)-PCT
360 test (360 cuts) – PCT –
DAA (AI Nutrition)- to supplement for the low DAA in 360 Test.
Crea-Trona (Redefine Nutrition) –PCT
Flaxseed oil (Store brand)- throughout the cycle
Horny Goat Weed-PCT
tribulus terrestris @ 40% -PCT
Yohimbine -PCT
Multi vitamin- through the cycle
Emergan C – throughout the cycle

My Cycle:
EPI-10 -20/30/40/30
Nolvadex 20/20/10/10
-I preloaded my cycle support and my fish oils for 2 weeks prior to my cycle.

Week 1: 20mg. of EPI 10
I saw very few gains on the first week. However, my body was well aware that a new hormone was being put into my body. I began feeling a little aggression about 30 to 60 minutes after taking my first dose. I began not having a lot patience for the little things, which was not easy with a 2 year old running around the house. My blood pressure did not elevate too much, and I really did not get lethargic. My strength gains were minimal. One thing I did notice was that my muscles were getting tighter and I was beginning to lean out. At this time, I was watching my calories because my main goal was to do a hard cut. I was already very lean, but I just needed something a little extra to shred that last few pounds of stubborn fat.

Diet for the first week:
I was maintaining a diet of around 2400 calories. I was in taking about 190 to 200+ grams of protein.
¾ cup of oatmeal
2 scoops of Myofusion Protein
1 cup of berries
-Snack -2 to 3 hours later:
6 oz. of turkey breast
4oz. of red potatoes
-Lunch (post workout)
2 scoops of Myofusion Protein
4 scoops of Cytocarb
& a cup of veggies
-Snack #2:
6 oz of chicken or turkey
½ avocado
Complex carbs (Potatoes, rice cakes, or oatmeal)
A protein shake or 6 oz. of protein
Veggies (usually a cup)
And a complex carb
I would have one to two cheat meals a week. I HAD NO ALCOHOL DURING THIS CYCLE!
I got exactly 7 to 8 hours of sleep a night, and more on my weekends.

Week #2: 30 mg of EPI10
On the second week, I began seeing that my patience was very short, and that I would get irritated very easily. I began feeling very lethargic, and my strength gains were not going up. However, I was adding weight. By the middle of week #2 was looking bigger, harder, and I was leaning out a lot. I began seeing veins in my shoulders and biceps. One side effect was pimples that started to appear on my face, chest and arms. They were not out of control, but more irritating and annoying. The pimples that were on my arm were only on my left arm, and there were only about 3 or 4 of them.
I stopped taking my PWO during this cycle, and I really could feel that my workouts were getting cut short due to the lack of energy. During my workouts, I can honestly say that I gave it everything I had to push hard and to give it everything I had. This was easier said than done, and I honestly could not find the energy to complete most of my workouts.
I got good sleep while on this cycle, and would never take a dosage after 6 pm. I started upping my carb intake to help combat the lethargic side effects. This helped a little, but did not get rid of the problem.
I got exactly 7 to 8 hours of sleep a night, and more on my weekends.

Week #3 40 mg of EPI10

At this point, I wanted this cycle to end. I realized that I should have either got Dermacrime or Stano to help with the lethargic side effects, but by the time I would receive it in the mail, my cycle would almost be over. I purchased DHEA in pill form (from a vitamin shop)and began adding it to my cycle. This helped a little, but again it did not give me the energy I needed to complete this cycle. I tried to up my cycle to 40 mg, but soon discovered that this only made it worse.

I really upped my carbs and began eating more crap food just to get some energy. I caught myself purchasing more sugary foods at the gas station, and I was not staying strict on my diet.
Pimples and aggression were still present, but did not increase from the prior weeks. I am able to maintain my aggression, and did not have any blowouts during this cycle. The aggression for me was just a lack of patients.
I did gain about 6 pounds at this time and my muscles were looking fuller and harder. My shirts began getting tighter, and I could really see that my lats were popping out. Again, my strength was not increasing, and luckily it not decreasing either.

I got exactly 7 to 8 hours of sleep a night, and more on my weekends.

Week #4 30mg of EPI 10
By this point I was done and could not take anymore. I took my cycle back down to 30mg, due to at 40mg my aggression was though the roof. I tired breaking up my dosage at the 3 week mark, and this defiantly helped lower the aggression a little.

I honestly wanted to take a nap every day at about 3pm. I got a good 7 to 8 hours of sleep every night, and still felt tired and lethargic. I really got bad at staying on my diet, just to combat the side effects.

However, I was really seeing a lot of gains. I now added a solid 10 pounds and looked lean and full. My shirts were even tighter, and my abbs were popping out. My veins were also popping out of my forearms and biceps. I increased my DHEA, and felt that it helped a little with the side effects.

I was going to run this cycle for 5 weeks, but decided to cut it short to 4 weeks.
I started my PCT the next day and I am currently on it. I feel more energy, not lethargic, and still look lean. My muscles are not as hard or full, but the size is still there. I am still seeing the veins in my arms and biceps.

One major side effect was the boating and gas on weeks 3 and 4. OMG, the gas was terrible, and I am surprised that my wife did not divorce me over it. I know that it was not my support supplements, because I had been taking them 2 weeks prior to my cycle. The gas I had on this cycle was a smell that I have never smelled before. Honestly, after a fart (and I had farts all the time), the stench would linger for 3 to 5 minutes, and even perfume would not mask the stench. I know this was from the EPI, and it truly smelled like the EPI tuned in my stomach. I tried fiber, gas x and laxatives to maybe flush out my bowels, but this did nothing. The smell only got worse and more often. The Gas X did help, but only for a few hours. I was popping Gas x like they were candy.



Would I recommend this cycle to a friend? Yes. – I honestly saw great results from this cycle; however, I feel that EPI hits me harder than others.

Joints get dry at about two 2 week mark along with dryness of the muscles. I did encounter some backpunps throughout my cycle, but I was able to combat that with taurine. I later had to up my Taurine to 6 to 10 mg, which did help a lot with the back pumps.

Would I run this cycle again? Maybe, and only with Stano.

I honestly had some great results from EPI, but the side effects really threw a curve ball on if I would do EPI again in the future. The gas and lethargic sides are the two major side effects that I encountered during this cycle.

The pills were easy to take, so I give a 10 on taste. I was able to complete a 4 week cycle with one bottle, and at Lockout Supplements one bottle runs at about $29. With all the support supplements my cycle ran me at about $150 or more.

LGI has a good reputation with the supplement community, and if I could talk directly to LGI, I would encourage them to maybe add EPI and Stano into one capsule. This would be awesome and would really help anyone who experiences lethargic sides with EPI.

This was my 1st cycle of Ph's and I have just finished Epi-10

I ran this at 30/30/40/40/40/40

Height 5'6
Stats at start Weight 147lb BF 17.3%

Results- The end results from the product were very good. I knew it would take a while for the Epi to kick in and I could feel the diff in the 3rd week. As I am small framed I do not want to get 'big' I wanted to get more toned and an issue I have is due to my work I generally train on my own so have no spotter to push my weights harder. My Bench went up 40lbs for 3x sets of 10 that I could comfortably handle on my own. I have no doubt if I trained with a partner I would be able to do alot more. Everything else I took up to the next couple of levels quite confortably

Sides- Took liv-52 and organ shield during cycle so didnt get any liver sides at all. Couple of nights I woke up drenched in sweat and couple of days got headaches. The only issue I would say is I got joint pains in my arm usually after doing bench press session. Think I would need to up the fish oil next time

For last 4 weeks I tried to cut some body fat so lowered my calories to about 2000/daily with 45/35/25 protein/carb/fat diet

Due to my lifestyle I found this extemely difficult as I work away and for one week was in a hotel working late nights (brought weights with me). I also hit the drink 3 saturday nights during the cycle (this was me cutting back alot)

End stats Weight 150lbs BF 16.8%

Im quite disappointed I didnt decrease bodyfat more as I did cut out all the crap I normally eat for 4 weeks and upped protein to over 150g during the cycle. Obviously I need to keep off the drink and be more stict with the diet.

That being said people have been commenting and asking have i been working out more. I feel alot stronger and look more defined but I want to lower the bf to under 15%

PCT started with novla/dpol/liv52 so hoping I keep these strength gains

This is my first review and first time using a ph, and since I'm starting my third week of pct thought I'd leave one. I researched all summer on how to do a proper cycle. Now to start researching for my second Il start next spring :)

I work out on average of 5 times a week. Been working out most of my adult life. I have used several natty cycles over the years, and busted my butt to get up to my starting weight. My stats: height 6'2" starting weight was 201 lbs and 10.5% body fat ( checked on tanita body composition analyzer), which is where I have been stuck for years. I wanted to get a lean bulk with epi, and I sure did! I upped my calories by 500-750 calories throughout cycle.

My supplements I used throughout: cycle assist, fish oil, glucosamine, animal pak multi, milk thistle, Super odorless garlic, Taurine, L-glutamine, aminos, and started T-force in week 3.

I dosed the epi at 30/30/30/40/40/50 for 6 weeks total. Day 1 was 10, days 2 & 3 was 20 with rest of week 1 at 30

PCT: Nolva at 20/20/10/10
Clomid at 50/50/25/25
I also used D-pol, 1.5 cans animal stak, animal M-stak, plus my normal supps of creatine and such.

Week 1: Didn't notice anything. Had zero sides, and no real weight change.

Week 2: Started feeling the epi by end of week. weight was up to 203 lbs but my bf was up a little as well to 10.8%

Week 3: Started feeling the atrophy at end of week 2, so started taking the T-force this week. Weight was going up 206 lbs and bf% was going back down 10.0%! Was getting slightly stronger now to.

Week 4: Still going great, with no sides so upped it to 40. The weights were getting light and I felt great in the gym! End of week I was 208 lbs with 9.5% bf. Vascularity in my shoulders and chest is amazing.

Week 5: Same as week 4. Awesome feeling like I could take on the world. Haven't felt like this in 10 years! End of week stats weight 210 with 8.9% bf!

Week 6: Started taking some DAA I had to get it preloaded. Still no sides and wanted to try 50 so upped it. Awesome feeling still. My squat and bench was actually as high as my football days 15 years ago! Ending week 6 weight was 211 lbs and 8.5% bf! I have never weighed this much with this low of bf! The pumps in the gym lasted for hours after my workouts and even the vascularity in my legs is just awesome to say the least!

I am currently in week 3 of pct. I feeland look amazing. Weight is still 210 lbs with 8.3% bf. Only lost 1 lb so far.

This stuff is awesome. I am still 9Lbs over my starting weight with over 2% less bf! I felt like I was 21 again throughout the whole cycle! I could feel the dryness of the epi but it was nothing unbearable, and the back pumps were there to but Taurine took care of them.
At under $30 a bottle the value is outstanding! I spend more on creatine and pre-workouts normally!
Thanks for reading and sorry so long a review,and if I missed anything(I'm sure I did). Just wanted to get it all in.

This was my second cycle of Ph's and I stacked this with Mlmg for a lean bulk.

I ran this at 30/40/40/50/50/50 and the mlmg at 75/100/100/125/125/125

My stats/PB precycle were weight-210lbs, Bench 275 for 5, squat 315 for 4.

Results- The end results from the product/stack were very good. I knew it would take awhile for the Epi to kick in, but the Mlmg I wasn't sure what to expect. Both kicked in on the 4th week, although frustrating but well worth it. Epi at 50 and Mlmg at 125 both kicked in strong, I knew at least the Epi was kicking because I could feel it hit my liver. So weeks 1-3 I didn't feel anything at all surprisingly, no strength increases or changes in the mirror. Weeks 4-6 I started bulking up and getting alot stronger, weights were feeling lighter, more reps etc. I ended up getting my PB at bench 315 2x (I could've got the 3rd but didn't want to push it too hard since my joints were bothering me, but thats for the "sides" section), but damn - I just know I could've got that 3rd and now regret not doing it lol.. Squats went to 315 8x. I thought the results were pretty good!!

Sides- Felt Epi hit my liver week 4. Nothing painful, just alittle uncomfortable, I just upped my cycle assist to 6 pills 2x a day instead of 4 pills and this helped alot. Also had some BP spikes toward the end of the cycle and now into PCT, no biggie there. What really bothered me as far as sides were the joint discomfort. This has me thinking I'll never do a dry compound again lol. It just made me feel constricted in how I felt throwing the weights around. I did up my fish oil and added Animal Flex to my stack and it def helped me manage the pain. Also had minor sleep issues from the middle of cycle till the end, I used AI's 3Z which helped and will do a review on that as soon as they add it.

Other supplements: my stack consisted of:
fish oil
Animal Flex
Up Your Mass (day shake pwo)
Muscle Milk (before bed shake)
T-force (help delay the boys from shrinkage and ackyness)
Vit. c,e
cycle assist
extra hawthorn berry (for the BP spikes)

Exercise/diet- were as always as strict as possible. wo 3x a week chest/tri's, shoulders/bicepts, back/legs.
Final body weight and still maintaining 3 weeks into PCT: 216lbs !!

I think the Epi really kept the Mlmg in check and vice versa.. Good cycle.
