Enanthate crazy bad PIP

Hi Chaps!

I'm new"ish" to the game, I've once before tried Bayer Enanthate 10 years ago and I had literally not a sign of PIP back then.

Fast-forward 10 years later and going for beast to obese (25% fat), I decided to up my game and gear up, and I got myself ProperLabs 300mg Enanthate.

PIP:
- It's just nuts, I've tried glutes for a few weeks and just couldn't take it no more, lumps & pin to the point I couldn't sit.
- I've maned up and tried quads, and although the pain is still there, I can at least walk & not worry about lumps. (No way I can do legs in the first 3-4 days)
- Yes I'm 100% sure I've done everything correctly, I even bought a massage gun.
(hot towel, massage, warm up the vial, watched many youtube videos how to get the injection just right etc, going straight to the gym after pin, pin after gym and so on)...
- I've ordered from a very well known website (similar name to the subreddit) and I've checked the QR code, chances of being a dodgy product are very very minimal.

After feeling desperate for a while I've looked into this subreddit and I see that a few other fellas are having exactly the same issue with this specific product.

I'd be so grateful if you guys could give me a "hand", information from veterans would really help me much.

- What should I change this testo for? (I can't find availability for Pharma E. so I can't really try it out).
- Would getting the 200mg solve my problem?
- Any recs for big & reliable suppliers would be truly appreciated.

Edit: I pin twice (500mg weekly), and I've got my blood tests booked for next week to see how this testo actually works.

Edit 2: Thank you very much lads, I've done as you guys recommended, I've got myself Cypionate

Edit 3: Thank you all lads you did sort out my issue, Cypionate did actually the trick, 0 PIP. Thank you all!!
