I want to start out by saying I wanted to do this review a little later, since I am just under 10 weeks of my cycle, but since I purchased the Primo just under 6 months ago, I wanted to make sure I fall into the sites rules and guidelines. Also, if I provide updates, it'll be on GK's discussion page. To start, a little background - I've tried different sources Primo 100, (not from this site), multiple times, and due to the pip, I had to tap out after a few weeks because the pip was crippling where I could barely move and let alone lift, (even mixing with other oils, heating, and praying before every pin session). However, I was informed from a friend to try GK's Primo. After some research and the constant Jano testing he does on all his gear, I felt comfortable to pull the trigger. I originally ordered 10 Primo 100, but he sent me 10 Primo 200's. I was ecstatic, but little worried I may not be able to handle the 200mg's. Therefore, I started with mixing .3 to .5cc Primo (100mg) with different sources Test C and Mast E - mixing and matching oils and pinning 6 times a week. Pinning every day, expecting pip sucks, but I was determined to make it work, so, the first 2-3 weeks, there was some pip, but not crippling, which was surprising, since I was expecting gnarly pip on Primo 200 mg's. For whatever reason, my body was adjusting to the Primo instead of rejecting it (finally, I might be able to run a full cycle of Primo!). Little by little, I was able to gradually up my injection amount and now my pinning cycle is MWF 1cc of Primo (200mg) + .7 Test C (175 mg) + .7 Mast E (140) for a total weekly of Primo 600mg + Test C 525mg + Mast E 420mg. It took me about 5-6 weeks into the cycle to dial in these numbers, since I started my Test C at 375, as it felt like my e2 was low and upping it to 525mg seems like my sweet spot. Ever since then, it's been a nice gradual climb upwards with my weight, (losing some belly fat and muscles look more full and dense - I noticed Primo is protein hungry, just make sure you feed your body enough of it or you'll feel hungry most of the day), the strength is minimal, but noticeable, but enough to keep adding some weights, sets, and reps. But the endurance is noticeable where I don't get too gassed out by the end of my workout sessions. The cool thing about this run so far is - I didn't really notice too much of a change, but very recently, people have been constantly complimenting on how good I look. That Primo look - ladies really love it....lol. I am starting to see striations on my shoulders, arms, and chest. Can't wait to see how the rest of the cycle goes! And overall, I hardly have any sides and feel great. As for my libido, it dropped a bit for a minute, but I think that was the e2 issue, but feeling good now. It's not like Tren, where I want to stomp every hoe, but enough libido to keep them satisfied. The fun part is, I am only halfway into this cycle, and with this experience, I will probably add some Primo to all my future cycles. For people that have not tried Primo yet, I say to find a source you trust and try one or two bottles. See how your body reacts to it and if you are not too prone to pip, give the cycle 100% attention to it (diet/workouts/sleep and recovery), the "Primo look" that has me dry, cut, veins, and abs showing is something people envy, lol - haters gonna hate. Especially being in my mid 40's and having no sides is well worth the money for a full Primo cycle imo. All about health and longevity for me these days.

My experience was great I had a few issues with my bitcoin account and had to cancel a few orders. But got those fixed and reordered everything with no further issues

Best gear I tried on this community. Previously running prescibed test on trt and switched to gk. Sex drive is soaring.

Best experience ever. Super Easy process. Great website. Simple and elegant. Awesome customer service! Be sure to make an acct before purchasing. I did not until after. My mistake.

Reviewing an order from early February. Experience was great. Website is easy to navigate, payment is a breeze, and shipping was quick. Price is on point! Products are proving to be great as well. Been running current cycle for 14 weeks. I've posted my recent blood work to show the effectiveness.

My experience with GK has been outstanding from the product to the results. This 4 month cycle from GK included 250mg Test cyp and 300mg Primo 2x times a week for a total of 500 test cyp and 600 primo. I originally got some upper chest, arm and shoulder acne. My power at the gym has been phenomenal and vascularity and muscles have increased big time. I also run 1cc of GK Cialis 50mg everyday. I haven't ran any AI but haven't experienced any high Estrogen side effects.

Great experience, Smooth and easy as possible. great communication, easy order and payment, fast shipping. smooth oils, no pip, moderate/expected gains and side effects. just about everything you could want from a source.

My experience was great the sit easy to navigate. The price was great . I have been shopping with them for almost a year .

Been using his products for the last 6 to months. Nothing but a great experience. I have used test e, Deca, primo, Anavar, gh and have ordered a bunch of stuff for a friend and He has also love the product. His customer service is top notch, will take of you should an issues arise. Fast shipping usually get my package in a week or week and half.

I started my first cycle a few months back and wanted to do so the right way, so I hired a coach and he recommended BuyGorillaKing (Silverback Compounds), as he used it himself and had his own Primo from them tested. I had no doubt that my NPP was properly dosed, but for peace of mind I like to get my oils tested. I knew pretty quickly that my NPP was spot on when I started putting on weight/size fast, while also staying lean. I started my blast at a little under 190lbs, and am floating around 215 now. Body fat has come up slightly, but still have striations and resting abs. It’s been crazy to see how much I’ve grown the past few months with these compounds, I’ve also struggled to put on size and never seemed to get over 190, until I decided to do my first blast through GorillaKing.

Everything was simple from browsing the website to the checkout process and making the payment. He answered all of my noob questions without getting annoyed or bothered and just generally seems like good people. I was happy with the entire experience and felt comfortable making a purchase

Still to this day the only source i use. Best Prices, fast ta time, great communication and definitely quality product. Going on 5 years of using gorilla.
Definitely feel that aggressive needed when on that cutter mix.

How do you feel on this stuff, tired, horny, aggressive, no change?
Im cutting so hard to say, say by day it’s different depending on food, however gym sessions are solid, no negative sex sides, and if i have any issue with that his cilais is crazy good.

How much weight and/or size did you gain?
I’m cutting so I’ve lost 20-25lbs but strength is still right there.
How is your appetite?
Appetite fluctuates depending on acid reflux etc, since I’m in prep / cutting phase.

Body fat up or down? Body fat is way down since i started my cut in January, steady 1-2lbs a week

PIP, Acne?
I’ve never gotten really an acne on any gear or types. Almost no pip what so ever unless I’m running the cutting mix, but that’s 300mg a cc, so i ended up pinning everyday to lower the amount of oil pinned and it’s worked out.

Other changes you've noticed.
I’ll have to say, these last few weeks when i started the winny I’ve noticed my look has been more grainy. Been loosing fat which is key but almost everytime i start his winny at aboit 6-8 weeks out, withing a couple weeks my body changes it’s look.

Cycle went great. Made best gains of an cycle I've done before, and in only 6 weeks. Started @ 234lbs around 15ish% body fat, ended @ 248lbs with basically same body fat % I can still flex my stomach and see my abs.

Best company I’ve ordered from. Shipping is crazy quick. Quality products and quality pricing. My only source now
Got my bloods back. They’re way up
